Calm, honest habit tracking
Most habit trackers turn missed days into failure. Aster doesn't. Miss a day and your streak pauses — it never resets to zero. And instead of just checkboxes, Aster shows you how your habits actually connect to your sleep, HRV, and energy.
You're on the list — thank you.
No spam. One email, when Aster is live on Google Play.
Coming soon to Google Play · Android first
Connect Google Health Connect — entirely optional, and fully private — and Aster correlates your habit completions against real biometric signals instead of guessing whether a habit is actually helping.
"Your HRV was 16% higher on days you kept ‘10-minute walk’"
No health connection? Aster works completely on its own too — every core feature works with zero setup and zero account.
A missed day is a pause, not a failure. Nothing resets to zero, nothing gets damaged.
See how your habits connect to sleep, HRV, and energy — computed entirely on your device.
Pick a color for each day you keep a habit, and watch the month bloom into something personal.
Export everything as JSON, anytime. Nothing is locked in, nothing is held hostage.
No account, no login, no backend server. Your habits and any connected health data live only on your device — read-only, never transmitted anywhere. Full details in the privacy policy.
Aster is in closed testing right now. Leave your email and you'll hear the moment it's publicly available on Google Play.
