How it works
- Start any day. The day number is the number of cents.
- Save daily, or batch it weekly: the week's total is shown when you tick seven days.
- Try it in reverse to front-load the bigger days.
Tips that keep it going
- Batching weekly is easier than 365 tiny transfers.
- Round-up features in banking apps are a natural fit for this challenge.
