Nought on two iPhones: the daily check-in on one, the progress screen on the other

One question a day

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.

The daily check-in screen asking cooked, or ordered, with an amount to hold to save

Watch it add up

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.
