Getting Started
What is MicroHabit Physics?
MicroHabit Physics treats your daily habits as forces in a physics simulation. Positive habits (exercise, reading, sleep) are "forces" that push your trajectory upward. Negative habits (social media, junk food) are "friction" that pull it down. The app calculates your momentum score and projects where you're headed based on your current habit patterns.
How does it work?
- Add Habits — Create positive forces (things you want to do) and friction (habits to reduce)
- Log Daily — Check off completed habits each day with intensity ratings
- Watch Your Trajectory — See your momentum score and 7-30 day projection update in real time
- Get Insights — Understand which habits have the biggest impact on your trajectory
What's the difference between Forces and Friction?
- Forces (Positive Habits): Exercise, reading, meditation, sleep—habits that accelerate your progress upward
- Friction (Negative Habits): Social media, junk food, procrastination—habits that create resistance and slow your momentum

Understanding Our Data Collection
What We Collect (And Why)
We collect minimal data to:
- Improve Stability: Firebase Crashlytics detects bugs automatically so we can fix them
- Understand Usage: Firebase Analytics shows us which features users love (no personal habit data is tracked)
- Show Relevant Ads (Free tier only): Google AdMob uses your interests to show ads you might find useful
How to Control Your Data
- Opt Out of Analytics: Settings → Privacy & Data → Toggle off "Diagnostic Data Collection"
- Control Ads: Visit https://adssettings.google.com to control Google ad personalization
- Remove All Ads: Upgrade to Premium—no ads, no ad tracking, period
- Disable iCloud Sync: Use the app locally with no cloud data if you prefer
