Check! Daily Habit Tracker

Check! is a simple, focused habit tracker built around one idea: every day
you care about, tap a topic once to check it off. That's it. No mood
sliders, no feature bloat — just a fast, satisfying way to track what
matters and watch it add up, day after day.

Whether you're running every morning, writing a book, learning a language,
logging commits, or building any habit worth keeping, Check! gives you a
clean, visual way to see your progress grow.


WHY CHECK!

One tap a day. Every topic you track is a single push per day. That limit
is the point — it keeps the data honest and the habit 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 in the past — 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 view shows your overall consistency
across all topics 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.

YOUR DATA IS YOURS

Check! syncs your topics, goals, and history securely through Firebase,
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
topics, history, and stats go with it.
