How the habit grid works
Habit Tracker Grid borrows a display you already know from contribution grids: lots of small cells, one per day, coloured by what you got done. Streak grid works just as well as a name, because the streak is what you see.
Add a habit
A name and a colour are enough. If you like, add a goal with a unit and a step size — 50 push-ups, 2 litres or 20 pages, say. Two habits are free and stay free, with no time limit.
Tick off the day
A tap on today fills its cell. For countable habits your progress counts up in your step size until the day’s goal is reached. If you like, the app reminds you per habit at a time you choose — turning notifications down takes nothing away.
Watch the streak
The grid fills up day by day. Completed days sit side by side and form a streak, gaps stay empty and jump right out. A whole month fits on one screen. After two or three weeks the grid shows your routine and your consistency at a glance.
This is what it looks like over weeks

Where your data lives
On your device and in your iCloud — there is no user account, no sign-up and no server of ours that your habits end up on. On top of that you can write a full JSON backup and restore it whenever you like, for instance when moving to a new iPhone. The details are in the privacy policy.
What Premium changes
Nothing about how you use it. Premium lifts the limit of two habits and unlocks 6 themes with a colour you pick yourself, your own background image and statistics. €4.99 a month or €14.99 a year, and the yearly plan starts with 7 days free. See the pricing
