Inertia — a free habit tracker for people who want discipline
Inertia is a free daily habit tracker built for people who want
discipline and follow-through — and who are tired of starting over. Tagline:
Turn your goal into a plan.
What Inertia does
- Tracks habits and tasks on flexible schedules (daily, weekdays, or specific days).
- Streaks for the habits you want to build.
- Clean-days tracking for the habits you want to quit — no alcohol, no doomscrolling, no junk food — counting how long you've gone without slipping.
- Progress by area: each part of your life levels up as you show up — momentum you can see, building over time.
- Focus timer with a Pomodoro work/break cycle, plus a meditate mode and a distraction-free fullscreen view.
- Mood logging and progress insights — a 60-day trajectory, a habit matrix, and a weekly quota.
Who it's for
People who want to lock in and build routines, who keep quitting after a week, and
who find most habit apps either too childish or too cluttered. Inertia is a clean,
dark, tactical dashboard — not cartoon gamification.
How Inertia is different
Inertia is built around discipline and follow-through. A single
missed day doesn't wipe you out: when a streak breaks you restart it
without losing your progress, so one slip doesn't make you quit
the whole thing. It tracks both the habits you're building and the ones you're quitting,
and it turns consistency into visible progress.
Platforms & price
Inertia is free. It runs in any modern browser and installs as a PWA
on iOS, Android and desktop. Sign in with Google or email and your data
syncs across devices. Try it at inertia.how.
