Edit individual weeks if a bonus week or a tight month changes what you can put aside. Your plan stays private in local storage on this device.
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.
Frequently asked questions
Can I edit one week's amount?
Yes. Change any week's amount and the totals recalculate. Useful for holidays or irregular income.
What currency does it use?
Amounts are unit-agnostic numbers with a $ label by default; treat them as your local currency.
Can I reverse the classic challenge?
Use custom mode with start 52 and increment -1, or edit weeks manually after generating classic amounts.
Does Week52 upload my savings data?
No. Progress is stored only in your browser's local storage on this device.
Is Week52 free to use?
Yes. The tracker, printable grid and all modes are free with no sign-up.
