Three calculators, no sign-up, nothing to install. Each one answers a single question with the numbers you type in: how to split a monthly income into needs, wants and savings; how many months of expenses to keep as an emergency fund, and how long it takes to get there; and how two partners with different incomes can share the bills fairly. The results stay on this page — nothing is stored. If you want the same numbers to follow you month after month, the app does the tracking part: type "coffee 15" and it's logged.
Add every subscription with its own billing rhythm and see the real total per month and per year — before the next renewal.
