Mood Patterns: Mood Tracker

Mood Patterns: Advanced Offline Mood Tracker, Journal & Data Analytics

Please Note Before Downloading:
Mood Patterns is not a simple “tap a smiley face” diary. It is an advanced, 100% offline mood tracker and analytics tool built for data-driven individuals who want to uncover real statistical correlations in their daily habits and emotional well-being. Because it uses Ecological Momentary Assessment (experience sampling) and continuous bipolar scales, there is a brief learning curve. If you want a basic journal, this app is not for you. If you want a rigorous tool to understand your emotional patterns with total privacy, keep reading.

No Forced Subscriptions. 100% Local Privacy.
Your mood and health data are intensely personal. Mood Patterns is built on a strict privacy-first architecture:
• Zero Internet Access: The app does not request or have internet permissions. No background uploads, no cloud sync, no ads, and no tracking.
• 100% Local Storage: Your data never leaves your device.
• Encrypted & Locked: All data is protected by 256-bit AES encryption (SQLCipher) and secured with an optional PIN or biometric app lock (fingerprint).

Transparent Pricing: Free to Use, Pay to Upgrade
We believe you should own your tools. Core experience sampling and mood tracking features are completely free to use. For those who want to unlock advanced analytics and unlimited custom scales, we offer a transparent Pro upgrade: choose between a low-cost monthly subscription or a 1-time Lifetime Unlock. You will never be forced into a perpetual subscription just to access your own data.

Experience Sampling (Ecological Momentary Assessment)
Classical end-of-day diaries suffer from recall bias—we mostly remember peak or extreme moments. Mood Patterns uses experience sampling (a method from psychological research) to prompt you at random or fixed intervals throughout the day, capturing your authentic emotional baseline and how everyday routines truly affect you.

Granular Customization for Data Enthusiasts
Don't settle for fixed categories. Your life is unique, and your tracking parameters should be too:
• Track context across people, places (with optional GPS), primary and secondary activities, factors, sleep (manual or via Health Connect), phone/app usage, photos, events, and multi-day periods.
• Use 30 predefined bipolar mood scales or create up to 50 fully custom, user-defined scales.
• Set custom alerts for emotional thresholds and schedule personal affirmations.
• Add Markdown-formatted notes and photos to your surveys for rich journaling context.

Deep Analytics, PDF Reports & CSV Export
Turn your daily habits into actionable insights:
• Explore your data through interactive, zoomable time-series charts, weekday & time-of-day profiles, and before/after event comparisons.
• Discover statistical correlations and rankings between your feelings, sleep, screen time, and external factors.
• Generate structured Weekly and Episode PDF reports, or export raw CSV data optimized for spreadsheets (Excel, R, Python) so you or your therapist can run in-depth multivariable analyses.
