Your totals, remaining balance and progress update live. Edit any week's amount, reset when you need a fresh start, and open the printable view for a clean one-page 52-week grid you can stick on the fridge.
How the 52-week challenge works
Pick a weekly plan: classic rising amounts, a fixed deposit every week, or a custom start amount plus increment. Mark each week when you transfer the money. Totals and the progress chart update immediately, and you can edit any week if life gets uneven.
Use the printable view for a fridge-friendly grid. Everything stays on this device in local storage until you reset it.
Private by design
Week52 has no server-side processing of your challenge. Your amounts and checkmarks never leave this browser.
