Private mood tracking
MoodStat is a gentle daily check-in that takes five seconds β free forever, with no account and no cloud. When you're ready to go deeper, optional Pro tools turn your logs into honest insight, all computed on your own phone.
Why MoodStat
The #1 complaint about mood apps is that core features are held hostage. MoodStat takes the opposite stance: everything you need to build the habit is free forever, and Pro only adds deeper reflection β never your own data, and never on someone else's server.
Logging, tags, notes, history, reminders, the widget, basic charts and full data export are free forever. Core journaling is never behind a paywall β that's the whole point.
When you want more, MoodStat Pro unlocks the detailed check-in, the insight engine, per-signal trends and the full report β the kind of depth usually reserved for clinical apps.
No fake AI therapist, no inflated claims. MoodStat shows you your own patterns and calls associations associations β never cause. A magnifying glass, not a treatment.
The daily check-in
Pick how you feel on a simple five-point scale, add a tag or a note if you like, and save. That's the whole thing β designed so you'll still be doing it in two months, and it never costs a cent.
Optional detailed check-in
Expand the check-in to record what's really going on β grouped into resources, emotions, cognition, behaviour and external factors. Every field is optional; a blank means "not recorded," never a zero. Creating detailed check-ins is part of MoodStat Pro.

Insights
See the shape of your weeks for free β and unlock plain-language explanations of what's moving your mood with Pro. Hand-drawn charts, no dark patterns, all computed on your device.
Basic mood charts and the 28-day calendar are free on every plan.
MoodStat Pro's insight engine correlates your tags and detailed signals with your mood, and writes it up in plain English β stated honestly as associations, never as cause.
A month at a glance shows the shape of your weeks β quiet streaks, rough patches, and the rhythm in between. Adjust every view to 7, 30, 90 days or all-time so the timeframe is never a mystery.
MoodStat Pro
Pro adds the tools that turn a mood log into understanding β computed entirely on your phone, like everything else in MoodStat. Nothing is uploaded, and your data is never held hostage.
β Change your mind? Detailed check-ins you already recorded stay visible and editable in History β even if Pro lapses. Only creating new ones needs Pro.
Deeper reflection tools β computed entirely on your device.
A discounted yearly plan is planned too.
Free forever: logging, tags, notes, history & editing, reminders, the widget, basic charts, and full CSV/JSON export.
Privacy-first, by design
A mood diary is one of the most personal things you can keep. MoodStat is built so that trusting it doesn't require trusting us β there's simply nowhere for your data to go, on either tier.
Nothing to sign up for and nothing uploaded β on Free or Pro. Your entries live in local storage on your device, and every insight and report is computed there too. Even the analysis never phones home, and it all works fully offline.
Your diary is not a dataset. MoodStat doesn't feed your entries to any model, ours or anyone else's.
No ads, no trackers, no analytics harvesting your behaviour. MoodStat is paid for by people who choose Pro β never by selling what you feel.
Export everything to CSV or JSON any time, and import it back β free, on every plan. Leaving is as easy as staying.

Good to know
Free forever: the daily check-in, tags, notes, history and editing, reminders, the home-screen widget, basic mood charts and the calendar, and full CSV/JSON export & import. MoodStat Pro adds the detailed check-in, the insight engine (weekly narrative + what lifts/lowers your mood), per-signal trends and pattern detection, and the full over-time HTML report. Core journaling is never held hostage.
Pro is planned at $4/month, with a discounted yearly plan. Subscriptions open when MoodStat reaches the app stores; there's nothing to buy yet, so you can start free today.
No. Detailed check-ins you already recorded stay visible and editable in your History even if Pro lapses β that data is yours. Only creating new detailed check-ins requires Pro.
On your device, in the app's local storage β on both Free and Pro. There's no account and no server, so nothing is uploaded, and every Pro insight and report is computed locally too. That also means backups are up to you: use the free CSV/JSON export any time. To move phones, export to JSON (restores everything) or CSV and import on the new device β importing never deletes existing entries.
No. It's a self-awareness tool for noticing your own patterns. It surfaces associations, not diagnoses, and it isn't a substitute for professional care. If you're struggling, please reach out to a qualified clinician or a local support line.
English, Polski, Π£ΠΊΡΠ°ΡΠ½ΡΡΠΊΠ° and EspaΓ±ol, selectable in-app. It also works fully offline β MoodStat needs the network for nothing.
