Check! is a simple, focused habit tracker built around one idea: every day you care about, tap a topic once to check it off. No mood sliders, no feature bloat — just a fast, satisfying way to build habits, track daily goals, and watch your streaks grow.
Whether you're running every morning, writing a book, learning a language, logging commits, or building any daily routine worth keeping, Check! gives you a clean, visual way to see your progress add up.

WHY CHECK!
One tap a day. Every topic you track is a single push per day. That limit is the point — it keeps your habit data honest and your streaks real.
Set your own goals. Default to a 300-day goal per topic, or change it to whatever fits: a 30-day sprint, a year-long habit, or an open-ended streak.
Miss a day? Add it back. Real life happens. Retroactive entry lets you fill in any missed day up to 30 days back — no guilt, no broken streaks over a forgotten tap.
See your progress. Every topic has a 30-day history chart and a progress bar toward your goal. A daily stats dashboard shows your consistency across all habits at a glance.
Stay organized. Tag topics, filter by active or finished, and reorder them with drag-and-drop so what matters most stays on top.

HOW IT WORKS
1. Create a topic — any habit you want to track
2. Set a goal, or keep the default
3. Each day you do the thing, open Check! and tap push
4. Watch your streak, history, and progress grow
5. Mark a topic finished when done, or start a fresh iteration

No gamification gimmicks. No social pressure. No pushy notifications. Just a clean, honest habit tracker that records the days you showed up.

YOUR DATA IS YOURS
Check! syncs your topics, goals, and history securely, so the same account works on web and mobile. Export everything to CSV any time — you're never locked in. Delete your account from Settings and your habits, history, and stats go with it.

START TODAY
The best time to start tracking a habit was yesterday. The second best time is today. Open Check!, create your first topic, and make the first check.

Check! — build habits, one daily check at a time.
