Chalk: Count & Settle

Chalk is a counter for the small things you pay for in batches. Therapy sessions, padel matches, lessons, coffees owed to the person who always gets them. Tap a counter to add one. That is the whole interaction. Give a counter a price and it does the arithmetic: four sessions at 90 euro reads as 360 euro owed. When you settle up, tap Settle. The count goes back to zero and the cycle is filed away with its total and its dates, so you can look back at what you paid and when. Settling is not deleting. Nothing you count is ever thrown away. • Tally marks, the way you would actually keep score • Home Screen widgets that count without opening the app • Lock Screen widgets and an Apple Watch app • Siri and Shortcuts: "tick therapy" • Undo, in case of a fat finger • Everything on your device, synced through your own iCloud No account. No server. Nothing collected.
