Mood Patterns: Offline Tracker

Mood Patterns: Advanced Offline Mood Tracker & Data Analytics

Please Note Before Downloading:
Mood Patterns is not a simple “tap a smiley face” diary. It is an advanced, 100% offline analytics tool built for data-driven individuals who want to find real statistical correlations in their habits. Because it uses Ecological Momentary Assessment (experience sampling) and highly customizable scales, there is a learning curve. If you want a basic journal, this app is not for you. If you want a rigorous tool to analyze your mental health 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 tracking.
• 100% Local Storage: Your data never leaves your device.
• Encrypted & Locked: All data is protected by 256-bit AES encryption and secured behind biometric app locks (fingerprint).

Transparent Pricing: Free to Use, Pay to Upgrade
We believe you should own your tools. The 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 premium model. While a monthly subscription is available, a 1-time Lifetime Unlock is always an option. You will never be forced into a perpetual subscription just to access your own data.

Experience Sampling (Ecological Momentary Assessment)
Classical diaries suffer from recall bias—we only remember extreme events at the end of the day. Mood Patterns uses experience sampling (a technique used in psychological research) to randomly prompt you throughout the day. This captures your actual emotional baseline and how routine activities truly affect you.

Granular Customization for Data Nerds
Don't settle for fixed categories. Your life is unique, and your tracking parameters should be too.
• Customize your inputs across people, places, activities, sleep, and events.
• Use 30 predefined mood scales or build up to 30 fully custom, user-defined scales.
• Adjust the granularity of your scales to fit your specific needs.
• Add markdown-formatted notes to your surveys for deeper context.

Deep Analytics & Exporting
Turn your daily habits into actionable charts.
• View your data through beautiful, zoomable graphs across any custom timeframe.
• Discover statistical associations between your mood and external factors.
• Export your graphs and raw data seamlessly. The export formatting is optimized for spreadsheet software, allowing you (or your clinician) to run complex, multi-variable analyses.

Take control of your data. Discover your patterns.
