The challenge
Expense apps get deleted in week two, and always for the same reason: typing. Logging a PKR 200 coffee costs more effort than the coffee. So the data stays thin, the charts stay empty, and the app stops being worth opening.
Our approach
We took typing off the critical path entirely. The camera reads receipts into itemised expenses. Voice entry turns a spoken sentence into a filed transaction. And instead of making people build filters to find anything, a search box answers questions the way they would actually ask them. The app opens instantly and works on a bad connection, because the common case is standing at a till, not sitting at a desk.
