Atomic Clock: Habit Tracker

Offline habit tracker with streak heatmap, Build identity, Stay private & Secure

⚡ The Offline Habit Tracker Built on Atomic Habits Identity System

No account. No cloud. No excuses. Just habits that actually stick.

Atomic Clock is the only offline habit tracker with bulletproof
native alarms, a GitHub-style streak heatmap, and identity-first
habit building — all without a single byte leaving your device.

🔔 BULLETPROOF REMINDERS
━━━━━━━━━━━━━━━━━━━━━━━
Other apps miss notifications on Xiaomi, Samsung, and Oppo.
Atomic Clock uses Android's native AlarmManager — the same
engine that powers your phone's clock app. Your reminders
fire exactly on time. Every time. Even in Doze mode.

━━━━━━━━━━━━━━━━━━━━━━━
📊 STREAK HEATMAP
━━━━━━━━━━━━━━━━━━━━━━━
See your consistency come alive with a 30-day GitHub-style
activity grid inside every habit. Watch it light up in your
habit's color. Visual proof of the person you're becoming.

━━━━━━━━━━━━━━━━━━━━━━━
🧠 IDENTITY-BASED HABITS
━━━━━━━━━━━━━━━━━━━━━━━
Inspired by James Clear's Atomic Habits — every check-in
is a vote for the identity you want. Not "I'm trying to run."
But "I am a runner." Track who you're becoming, not just
what you're doing.
