Habit tracker · web & AndroidOne check a day. Progress you can see.
Pick what you want to work on – running, a language, reading, anything. Every day you do it, tap “Check!”. Check! keeps track of the count, the goal and the history, so you can watch small steps add up.

Tap “Check!” – that’s every day in Check!
How it works
Three steps. Every day.
Add a topic
Name what you want to do regularly and set a goal – a month, a quarter, a year or your own period, with leeway for bad days.
Tap “Check!”
Once a day, when it’s done. One tap – the counter goes up and the day is recorded.
Watch your progress
The goal bar, calendar and stats show how consistency turns into results.
Features
Everything you need. Nothing you don’t.
Check! is simple on purpose – but it has what actually helps you stick with it.
One check a day
Each topic can be checked once per day. That limit is the point – the data stays honest and the habit stays real.
Your own goals
Pick a period and some leeway – a month with 10% leeway means 27 checks instead of 30. When you reach it, finish the topic, start a new round or keep going.
Back-fill missed days
Forgot to tap? Add a missed day up to 30 days back – no guilt.
Calendar & stats
A day-by-day calendar, a year-long activity map, streaks and records – the whole picture, not just today.
Reminders
Set notification times in the Android app so no day slips by.
Tags & ordering
Group topics with tags, filter active and finished ones, reorder the list by dragging.
CSV export
Your data is yours – export your topics and your full check history.

Knowledge
More than a tracker
Guides with interactive tools that help you understand how consistency works.
Missed a day? What you really lose – and what only your streak loses
