Help & FAQ

Moon doesn't analyze every entry the moment you save it. Instead it looks at whole periods, where the real patterns are:

Day recap — one analysis of your entire day, available once the day is over. Week recap — a summary of your week. Month recap — the big picture of your month. Year recap — your whole year as one story.

Every day, week, and month recap opens with a picture the app draws from your own entries (see "What are visual recaps?" below). The AI text is never generated by itself — you're in control: tap Get deep analysis (in a year recap, Generate Recap) when you want it. Each day, week, month, and year can be analyzed once: deleting a recap doesn't make room for a new one.

Generating takes a few moments. You can switch to another app meanwhile — just don't close Moon. The ⋯ menu at the top of a recap shares it as a PDF or deletes it.

Every new install starts with a free trial of Premium+ (at least 14 days, always long enough for two week recaps), so all recaps are available from day one. After the trial, the visual recaps and the AI recaps of weeks, months, and years come with Premium; the AI recap of each day comes with Premium+.

Every finished day, week, and month gets a recap that the app draws itself, straight from your entries and ratings — no AI, no waiting, nothing to generate. It is there as soon as the period is over and counts every entry, including rating-only and Local Mode ones.

Day — your entries on a timeline by the hour, how the day compares with your usual and with the same weekday before, factors that came back after a long pause, and sleep and steps if Apple Health is connected.

Week — how the week went day by day, which days and times of day ran above or below your usual, the week's main factors, and its best and hardest moments.

Month — every day of the month in its mood colour, how many days were good, average, or hard, how the month compares with earlier months, and its main factors.

Tap a day or an entry in the picture to open it. Want the reasons behind the picture? Get deep analysis adds the AI text on top. Visual recaps are part of Premium (and of the free trial); without a subscription you see their outline with an Unlock with Premium button at the end.

First things first: every new install gets Premium+ for free for at least 14 days — no purchase, no card, nothing to cancel. When the trial ends you're on Free until you subscribe.

Free — the full journaling core: mood logging, notes, journal, calendar, the mood chart, search, the Daily and 4× a Day reminders, widgets, iCloud sync, plus manual iCloud backup (Back Up Now) and restoring your data from a backup file or iCloud.

Premium — everything in Free, plus visual day, week, and month recaps, Rhythms, three trend lines on the mood chart, and custom reminders; the AI: week, month, and year recaps, Fills & Drains, the "What changed" card, voice input, and Apple Health context in the analysis; automatic iCloud backup, data export, and the app lock with a 4-digit PIN.

Premium+ — everything in Premium, plus the AI recap of every single day.

Both plans come monthly or yearly; current prices are shown on the purchase screen in the app. Already subscribed on another device or reinstalled the app? Settings → Restore Purchases brings your plan back.

It starts by itself the first time you open Moon: at least 14 days of Premium+ — visual and AI recaps, Rhythms, the trend lines, Fills & Drains, voice input, automatic backup, Apple Health context, the App Lock. No purchase, no card details, no Apple sheet, and nothing to cancel.

The trial always covers two week recaps. A week's recap unlocks on the Monday after it, so if you install mid-week the trial runs a few days longer than 14 — through the Wednesday after your second recap Monday — so you get to read both.

To see how much is left, open Settings → Subscription: the plan reads "Free trial" with the date it ends. The purchase screen shows the same date.

When the trial ends, Moon tells you once, with a short note on what pauses and a Subscribe button, and then simply goes back to Free: the journal, calendar, mood chart, search, and manual backup keep working; new AI work stops, and the visual recaps, Rhythms, and trend lines lock until you subscribe. Everything generated during the trial — recaps, factors — stays yours and stays readable. Entries you write after the trial without a subscription are not analyzed later, even if you subscribe.

Liked it? Subscribe any time from Settings or from any locked feature's Unlock button. The purchase screen shows exactly what you'll pay and when.

The trial is tied to your iCloud account: reinstalling the app or opening Moon on a second device continues the same trial rather than starting new ones.

In the app: Settings → Change or Cancel Plan — this opens Apple's subscription sheet, where you can switch between Premium and Premium+, change between monthly and yearly billing, or cancel. The same sheet is available in your App Store account settings.

If you cancel, you keep full access until the end of the period you've already paid for — the plan simply doesn't renew. Note that deleting the app does not cancel a subscription. (The free trial is different: it isn't a subscription, so there's nothing to cancel — it just ends.)

Upgrading Premium → Premium+ takes effect immediately — Apple refunds the unused part of the old plan and charges the new one. Downgrading Premium+ → Premium, or switching between monthly and yearly billing on the same plan, takes effect at the next renewal.

Whether the free trial ends or a subscription lapses — nothing is deleted, ever. Your entries, recaps, and extracted factors all stay on your device and in your private iCloud, and every recap that was already generated remains readable.

Free simply stops new AI work: no new recaps and no new factor extraction, and entries written on Free are not analyzed later, even after you subscribe again. The Fills & Drains view itself locks — your factors are kept, but hidden until you subscribe again, and then they reappear exactly as they were. Visual recaps, Rhythms, and the trend lines lock the same way and come back with a subscription, since they are drawn from your entries. Your journal, calendar, mood chart, and search keep working as always.

No. The AI analyzes only entries made while a subscription or the free trial is active. Entries written without one stay in your journal, calendar, and charts, but they never reach the AI — not in recaps, not in Fills & Drains, not in the "What changed" card — even if you subscribe later.

Everything from your subscribed time stays in. Say you subscribed in January, stopped in February, and came back in May: your recaps and Fills & Drains count January and everything from May on, and February to April are left out. A short line under the recaps and Fills & Drains reminds you of this; tap "Got it" to hide it.

This way you pay only for the analysis you use: a month bought after a long free stretch goes to your new entries, not to months of old ones.

The App Lock protects your diary with a 4-digit PIN: the app asks for it every time you open Moon or return to it. Turn it on in Settings → App Lock; there you can also change the PIN or enable Unlock with Face ID so you rarely have to type it.

Forgot your PIN? Tap "Forgot PIN?" on the lock screen and confirm with Face ID / Touch ID or your device passcode — then simply set a new PIN. Nothing is erased, your entries are safe.

The PIN is stored only on your device, in the system Keychain — it never leaves your phone and isn't part of backups. Deleting the app removes it, so a fresh install starts unlocked.

The App Lock is part of Premium (and of the free trial). If the trial ends or your subscription lapses, the lock pauses (stops asking) but your PIN is kept — subscribe and it picks up right where it left off.

Two places:

Calendar — tap a day that has entries, then tap the ✦ sparkle button in the top corner of the day's list.

Insights — switch the chart to D: the recap card under the chart points at the displayed day (for today it shows "Yesterday's recap", since today isn't finished yet).

A day's recap opens the next day — a finished day is what makes it honest. If you logged anything today, tomorrow at 9:00 Moon lets you know the day's recap is ready. These notifications can be turned off in Settings → Notifications → Recap Notifications.

The visual day recap is part of Premium; the AI text of the day comes with Premium+. The free trial includes both, so you can try them from your very first day.

Week recap: open Insights in the W period — the recap card under the chart follows the week you're looking at. If you logged at least one entry during the week, Monday at 9:00 you'll get a reminder. One recap per week.

Month recap: switch the chart to M — the card points at the displayed month (for the current month it shows last month's recap). A reminder arrives on the 1st. One recap per month.

Year recap: switch the chart to Y — the card points at the displayed year (for the current year it shows last year's recap). There's no reminder for it. One recap per year.

Week and month recaps open with a visual recap drawn by the app. The AI text for all three comes only when you tap Get deep analysis (for the year, Generate Recap), and the longer the period, the deeper the analysis looks — the year recap builds on your months, the month recap on your weeks, the week recap on your days.

Month and year recaps also describe your mood rhythm: which weekdays and times of day usually run higher or lower for you, and whether this period held that pattern or broke it. Your first two week recaps describe it too, so you meet it early.

Week, month, and year recaps are part of Premium — and of the free trial.

The visual recap needs no generating. When the AI text can't be generated, the recap screen says why. The usual reasons:

The period isn't over yet. A day's recap opens the next day, a week's on Monday, a month's on the 1st, and a year's on January 1.

It was already analyzed. Each day, week, month, and year gets one recap, and deleting a recap doesn't make room for a new one.

There's nothing to read. The AI works from your notes, so a period with mood ratings only has nothing to analyze — its visual recap is still there.

All of the period's entries were made in Local Mode or without a subscription. Such entries never reach the AI. In Local Mode the screen offers Switch to AI Mode: entries you write after switching can be analyzed.

Your plan doesn't include it. The AI recap of a day needs Premium+; week, month, and year recaps need Premium. And if the AI allowance for your billing period is used up, recaps pause until it renews.

Yes. As you log, Moon quietly accumulates your mood rhythm: which weekdays tend to be your best and worst, and how your mood usually runs across the day — morning, afternoon, evening, night.

You can look at it any time in Rhythms (see the next question), and the visual week and day recaps set each period against it.

The AI talks about it too: the month and year recaps, and your first two week recaps, look at your rhythm over your whole history and over that specific period, then compare the two — did this month follow your usual pattern, or did a normally hard weekday suddenly turn good?

The rhythm needs repetition to be honest, so it only speaks up once a weekday or a time of day has enough entries behind it — with regular logging, a few weeks is enough.

Rhythms is a dashboard of your long-term patterns. Open it with the pulse button at the top of Insights, next to the gear. Everything in it is computed on your phone from your 1–7 ratings, with no AI, and Local Mode entries count too. It updates once a month, on the 1st.

Inside: a month score out of 100 (your average, good and low days, how steady the days were, and how quickly you recover after a low day), every month at a glance and the year in pixels, your best day of the week, time of day, and month of the year, how fast you bounce back after a bad day, sharp swings, streaks, and how often you log.

Diary extract turns the last 30 or 90 days into a PDF — one line per day with your mood, your words, and sleep from Apple Health — handy to show a psychologist or a doctor. The share button at the top saves the whole Rhythms screen as a PDF.

The statistics need time: they appear once your first five weeks have passed, and until then a "Still collecting" card shows what's missing. Rhythms is part of Premium (and of the free trial); without a subscription you see its outline with an Unlock with Premium button at the end.

If you connect Apple Health in Settings, Moon reads exactly four things, read-only: sleep, workouts, steps, and active energy. Nothing else — no heart rate, no HRV, no other medical signals.

This data adds context to your recaps: the day recap sees that day's sleep and activity, and the week, month, and year recaps include a short factual line — average sleep, workouts, steps — compared with the previous period. The AI states these facts and never interprets them: no physiology theories, no body-mood conclusions unless your own notes make the link. The visual recaps show sleep and steps next to your mood as plain figures, and the Rhythms diary extract lists each night's sleep.

Health data is read on your device per recap and is never stored on our servers. You can disconnect at any time in Settings; iOS-level access is controlled in the Health app under Data Access. Apple Health context is part of Premium (included in the free trial).

Behind the gear in the top-right corner of the Insights tab. One screen, in labelled groups: Subscription (your plan and AI usage), Support (Write to us, help, rating the app), AI and Privacy (AI Mode / Local Mode, Apple Health), Security (the App Lock), Notifications (reminders and recap notifications), Appearance and Language, Data (iCloud sync, backup, export), and Legal.

Yes. Moon is available in 13 languages: English, Chinese (Simplified), Dutch, French, German, Italian, Japanese, Korean, Polish, Portuguese (Brazil), Russian, Spanish, and Turkish. By default it follows your iPhone's language.

To pick a different language just for Moon, open Settings → Language: it takes you to Moon's page in the iPhone Settings app, where you choose the language. Recaps are always written in the language of your entries, whatever language the app is in.

AI Mode (default if you consented) — your entries are analyzed by AI: day, week, and month recaps, plus Fills & Drains factors extracted from your notes. Entry text is sent anonymously through a secure proxy, isn't used for training, and is kept no longer than 30 days.

Local Mode — full privacy: entries created in this mode are never sent to AI, period. They stay on your device and in your private iCloud. Everything else keeps working — calendar, journal, charts, search.

Switch between modes in Settings (the gear in Insights). The mode applies to entries you create while it's on: entries made in Local Mode stay local forever, even if you switch back — so the AI recaps and Fills & Drains simply don't see them. What your phone computes by itself does count them: the visual recaps, Rhythms, and the trend lines. That's also why, while Local Mode is on, Moon offers Switch to AI Mode where a subscription would only unlock the AI: a plan alone would have no new entries for it to analyze.

Fills & Drains highlights what tends to lift your mood (Fills) and what tends to lower it (Drains), based on factors the AI extracts from your notes.

It appears in Insights once something repeats: the same factor (say, "sleep" or "work") has to be mentioned in at least two entries, and the average mood of those entries has to lean clearly positive or negative — a factor sitting in the neutral middle stays hidden. With one–two entries a day, expect the first factors within the first week or two.

The chips at the top of the card switch between three sort orders: Impact (default) — how strongly a factor moves your mood, weighted by how often it appears; Mood — best fills and heaviest drains on top; Count — the most mentioned first.

Tap any factor to see every entry behind it. Entries made in Local Mode are not analyzed and don't feed Fills & Drains. Fills & Drains is part of Premium — and of the free trial, so a new diary sees its first factors before ever being asked to pay.

Fills & Drains is the all-time picture: what tends to lift your mood and what tends to lower it. The What changed card next to it answers a different question — what moved in this period. It sits in Insights between the recap card and Fills & Drains and follows the chart: in the W view it is "What changed this week", in M this month, in Y this year. The day view has no card — a single day has no dynamics. Page the chart back and the card follows.

It compares the period on the chart with the equally long period right before it: this week with last week, August with July, 2026 with 2025. A period that is still running is compared fairly — Tuesday of this week is set against Monday–Tuesday of last week, not against the whole of last week. Only rated entries with a mood other than neutral count, and a factor counts once per entry — exactly as in Fills & Drains, so ×5 here is the same ×5 there.

Four groups, each showing its five biggest shifts, with Show all for the rest:

New — factors mentioned for the first time ever in this period, at least twice.

More often — at least two more mentions than before, and at least twice as many.

Less often — at least two fewer mentions, and at most half as many. A drop to zero counts: the factor that went quiet is the one a plain list of this period could never show.

Mood changed — the mood you logged alongside a factor moved by a full point or more against its whole history before the period, with at least three mentions on each side. "Sea" used to come with 5–6 and now comes with 3–4.

The dot colour is the factor's all-time average mood, as in Fills & Drains. The figures are plain counts: ×N mentions, +3 or −2 for the change, and in the last group a mood difference with a decimal.

Tap a row to see the entries behind it within that period. The chevron in the header folds the card down to its title, and it stays folded until you open it again. The card appears only once there is something older than the period to compare with, and stays hidden for a period without rated entries; when nothing crosses the thresholds it says "No notable shifts". Entries made in Local Mode are not analyzed and don't count. Part of Premium — and of the free trial.

Right away — from your very first entry. Open Insights: the line chart shows your mood over Day, Week, Month, or Year (D / W / M / Y).

D plots each entry of the day on a time axis — tap a point to open that entry. W / M / Y show one point per day (the day's average). Use the arrows to move between periods. The more days you log, the more the lines have to say.

Yes. Open the Journal tab and tap the magnifying glass. You can search by words in your notes, filter by mood using the seven colored faces under the search field, or combine both — for example, every entry where you felt great and mentioned "training".

Tap several faces to include several moods at once.

Yes. Choose a mood, then tap Skip on the note screen to save a mood-only entry.

Yes. On the mood selection screen tap Skip in the top-right corner to go straight to the note and save a note-only entry. An entry is only created when there is a mood rating or some note text.

A note-only entry is a full citizen of the analysis: it feeds the day, week, and month recaps and the Fills & Drains factors just like a rated one — only the charts skip it, since there's no number to plot.

Open the Calendar tab and tap the day you want. If that day has no entries yet, the mood logger opens for that date — pick a mood, add an optional note, and save. The entry is stored on the day you tapped, not today.

If the day already has entries, tapping it opens the day's list — use the + button there to add another. Press and hold a day to jump straight to the mood logger.

Yes — Settings → Notifications has three reminder options, and only one of them can be on at a time:

Daily Reminder — one notification a day at 21:00.

4× a Day Reminder — four notifications at 10:00, 14:00, 17:00, and 22:00, if you want finer-grained tracking. More entries per day also means richer day recaps and better factor detection.

Custom Reminders — up to 8 reminders a day at the times you choose. Part of Premium; if it ends, Moon switches to the Daily Reminder at 21:00 and keeps your times for later.

Separately, Recap Notifications arrive at 9:00 when a day, week, or month is over and its recap is ready — on the 1st also when Rhythms update. You can turn them off in the same section.

Yes — for both the home screen and the lock screen.

Home screen: a widget with seven mood buttons so you can log a mood with one tap. Add it by long-pressing your home screen, tapping +, and choosing Moon.

Lock screen: a circular widget with the Moon logo — tap it to open the app and log your mood. Add it by long-pressing your lock screen, tapping Customize → Lock Screen, then the widget area, and choosing Moon.

The daily score is the average of all moods you logged that day.

The weekly and monthly scores are the average of those daily scores — every day with at least one entry counts equally, so a busy day doesn't outweigh a quiet one.

Next to the average in the chart header, an arrow compares the period on the chart with the one before it: a day with the day before, a week (Monday to Sunday) with the previous week, a month with the previous month, a year with the previous year. The number shows how much your average went up or down. For a period that is still running, the average so far is compared with the whole previous period.

In the M and Y views of Insights, three trend lines can sit on top of your mood line: your average mood over the last 14, 30 and 90 days. The 14-day line reacts fastest; the 90-day line shows the long course. The day and week views have none — over seven days these averages barely move. The lines are computed on your device, with no AI. They are part of Premium (and of the free trial); without a subscription the chips under the chart show a lock.

How they are calculated. For each day, Moon takes your daily averages from the preceding 14, 30 or 90 days, counting only days with a rating. It is a weighted average: the more recent a day, the more it counts, so the line follows a change without jumping each time a day enters or leaves the window. A light smoothing pass then removes small ripples.

When a line appears. A point is drawn only when the window holds enough rated days — at least a fifth of it: 3 days for 14, 6 for 30, 18 for 90. Across a stretch without entries the line runs straight on to the next stretch with data, and it ends exactly where your mood line ends.

Showing and hiding. The chips under the chart switch each line on or off. While at least one line is on, the scale on the right zooms in to your data so the slope is visible; with all three off it is the usual 1–7 again. The line colours are deliberately outside the mood colours: a trend line never stands for a mood rating.

Yes — a fair-use allowance per user. For normal journaling you won't notice it. Extremely heavy use — hours of voice dictation or pasting massive texts day after day — can approach it. The allowance renews with each billing period: every month on a monthly plan, every year on a yearly plan.

The app tells you as you get close (you'll see a warning around 70% of the allowance, and the current level is always visible in Settings → AI Usage). If the allowance runs out, the AI features pause until your next billing period — your entries, charts, and everything else keep working as usual.

Yes. In Settings tap Export Data — Moon saves a JSON file with all your entries and recaps. Choose iCloud Drive in the picker to keep a backup in your iCloud, or share it anywhere else. Your data is yours.

Export is part of Premium (and of the free trial); the manual iCloud backup (Back Up Now) and restoring from a file or from an iCloud backup are always free — you can get your data back on any plan. Only the automatic backup needs Premium. iCloud backups are encrypted on the device and in iCloud.

Your entries live in your private iCloud account (Apple CloudKit) — we can't read them, and there are no ads. Moon does collect anonymous usage statistics under a random identifier: which screens are opened and which features are used, such as "an entry was saved" — never the text of your entries, your mood ratings, or health data. If you installed Moon from an Apple Search Ads ad, Apple tells us only which ad it was, without any advertising identifier.

Backups are encrypted at every step: the automatic backup file is protected with iOS Data Protection on your device (unreadable while the phone is locked), and every copy in iCloud — the synced database and the backup file — is encrypted in transit and at rest. Apple manages those keys unless you turn on Advanced Data Protection for your iCloud account, which upgrades the iCloud copies to end-to-end encryption.

AI features send entry text anonymously through a secure proxy to the models; the data isn't used for training and is kept no longer than 30 days. Apple Health data is read on your device and never stored on our servers. Want zero AI processing? Use Local Mode. See the Privacy Policy for details.

In Settings, tap Write to us — the first row of the Support group, near the top. Type your message, add your email so we can reply, and attach a screenshot if it helps.

Along with the message, Moon sends a few technical details — app and iOS version, device model, language and time zone, your plan, how many entries you have, and whether sync, Local Mode, and Apple Health are on — so we can help faster. Your entries themselves are never included, and your email is used only to reply. If you close the form before sending, your draft is kept for next time.
