SpentSy is a budgeting app for people who want one number, not a spreadsheet.
Tell it what comes in, when it arrives, and what is already spoken for — rent, bills, subscriptions. It works out what is genuinely yours to spend and shows it as a daily, weekly or until-payday figure. The budget cycle runs from one payday to the next rather than from the first of the month, because that is how money actually arrives.
Logging an expense takes a few taps. Everything stays on your phone: no account, no sign-up, no server.
