What you don't buy, you keep.

The daily check-in

One question: did you spend, or didn't you. One tap answers it. A clean day banks the amount you set, and that's the whole day's work.

Streak saves

Slipping doesn't end it. A small pool of saves absorbs the days that go wrong, and the run carries on. Spend them when you need them.

Progress

What you've banked, set against what you're saving for. The calendar behind it keeps every clean day and every spent one, so the run is easy to read.

Pro

Several challenges at once, Home and Lock Screen widgets, history and lifetime stats, iCloud sync. Free gives you one active challenge with the full loop, nothing held back.
