Build habits that stick on their own.
Habitbi is a habit tracker with a GitHub-style heatmap, streaks, schedules and Google Calendar sync — installable as an app on your phone, no friction, no cost to get started.
Installable as a PWA · No credit card for the free plan
Everything you need to stick to a habit
GitHub-style heatmap
See years of consistency at a glance — daily intensity, streaks and records, just like the GitHub contributions graph.
4 habit types
Checkbox, number (with a daily goal), options and time (with multiple sessions per day) — every habit is logged the way it should be, not forced into "yes/no".
Google Calendar sync
Your habits and time sessions show up as events on your calendar, no need to open the app to see them.
Installable as a PWA
Installs on your phone or desktop like a native app, works offline and updates itself.
Real analytics
Yearly stats per habit: best streaks, averages, trends — not just a daily check that gets lost in time.
Your data, secure
Firebase authentication, data isolated per user, never shared or sold to third parties.
Free. Actually free.
Every feature — unlimited habits, the heatmap, Google Calendar and Outlook sync, analytics — is free, with no usage limits or paywalls. If you'd like to support active development, you can optionally join with a $3/month subscription — entirely up to you, and it doesn't unlock anything extra.
