SoulSync: Mood Tracker & Diary

Raedus Labbs

About this app

SoulSync is a private mood tracker and journal that keeps every entry on your phone. No account, no cloud, no ads, no tracking. Just an honest record of how you feel and clear insights into why.

Log your mood in seconds, then watch weeks of entries turn into charts and plain-English patterns you can actually use.

TRACK YOUR MOOD
Rate each day on a 10-point scale, with decimal precision if you want it. Add a note, attach photos, and tag what you were doing. Set the exact date and time for any entry, or edit it later, so a day you forgot to log is never lost.

ACTIVITIES THAT MATTER TO YOU
Tag entries with activities like Exercise, Sleep, Work, and Social, or create your own with a custom icon. Drag to reorder them so the ones you use most stay on top.

SEE YOUR PATTERNS
The Statistics tab shows where your mood really goes, not where you think it goes:
- Mood trend line with an adaptive moving average
- Mood heatmap calendar (darker means a better day, at a glance)
- Day-of-week breakdown, so you know when you reliably feel best and worst
- Mood distribution and activity correlation: what genuinely lifts your mood, and what drags it down

INSIGHTS IN PLAIN ENGLISH
The Insights tab reads your data back to you without the guesswork. Things like "you tend to feel best on Tuesday" or "when you log Work, your mood averages 6.8, that is +2.0 above days without it." It also tracks your logging streak, so a daily check-in stays a habit.

YOUR WHOLE HISTORY
Every entry lives in the Timeline in date order, with its mood, activities, notes, and photos. Scroll back through your own story, and edit or delete anything, anytime.

GENTLE REMINDERS
Set a daily reminder for a time that suits you. Tap it, log your mood, done. A 30-second check-in is all it takes to keep the habit going.

MAKE IT YOURS
Five built-in themes: Dark, Light, Cherry Blossom, Midnight Blue, and Forest. Switch whenever the mood strikes.

TRULY PRIVATE, BY DESIGN
Everything lives in a database on your device. Photos stay in on-device storage. Nothing is ever synced to a server, because there is no server and no account. There is no analytics SDK, and the app has no internet permission for your data.

You stay in control. Back up your entries to a JSON file whenever you like, and restore them on this phone or a new one. Delete the app and your data goes with it, because it only ever lived with you.

OPEN SOURCE
SoulSync is open source under the GPL-3.0 license. Read the code, fork it, and verify the privacy claims yourself:

Whether you are looking after your mental health, building a self-care habit, keeping a mood diary, or just curious what shapes a good day, SoulSync gives you the record and the insight without asking for anything in return.
