SoulSync: Mood Tracker & Diary

Raedus Labbs

About this app

Your mood, beautifully tracked — and 100% private. 🔒

SoulSync turns 10-second daily check-ins into gorgeous charts and plain-English insights. No account. No cloud. No ads. Your data never leaves your phone.

✍️ LOG A DAY IN SECONDS
Rate your mood on a 0–10 scale (decimals welcome — a 7.5 kind of day is real), tag what you did, add notes and photos. Forgot a day? Backdate any entry with the exact date and time.

📊 CHARTS A DATA NERD DREAMS OF
• Mood trend lines with adaptive moving averages
• Hold your finger on any chart to scrub day by day — see that day's average mood and the entry you actually wrote
• Tap a chart to go full-screen, then flip on Fit to zoom the scale to your own range instead of the full 0–10
• Swipe left or right on Statistics to step back through weeks, months, quarters, and years
• A heatmap calendar of your whole year at a glance
• Day-of-week patterns — when do you really feel best?
• Distributions, correlations, streaks… it's all in there

🔍 DEEP-DIVE ANY ACTIVITY
Tap any activity for its own analytics: its mood distribution, whether it's a "hit or miss" activity, how days with it compare to your usual — and what it tends to pair with.

💡 INSIGHTS IN PLAIN ENGLISH
"Days with Exercise average +2.0 mood." "When you're in a rough patch, Social is what's usually followed by a lift." SoulSync reads your data back to you: what lifts you, and what drags you down.

🕰️ YOUR WHOLE STORY, SEARCHABLE
Every entry lives in a timeline you can search by words or activities and filter by mood range. Delete something by accident? Undo it, or pull it back from Recently Deleted for 30 days.

🎨 MAKE IT YOURS
Five themes (Dark, Light, Cherry Blossom, Midnight, Forest), as many gentle daily reminders as you need, drag-to-reorder activities and groups, custom icons.

🔐 PRIVATE BY DESIGN
Everything stays in a local database on your device. No account, no server, no analytics. Back up to a file anytime; restore on any phone.
