Unbroken - Habit tracker with one job: make today obvious, keep the run

Add a habit, pick the days it belongs on, check it off. The number on the home screen is your current run of days, and that is the whole loop. Only what is due today is shown, with a big streak count and a clear done state. Current and longest streak per habit, a month calendar that shows the shape of your consistency, reminders that skip tonight if today is done. Seven languages, widgets, no account.
