WHAT MAKES TALLYN DIFFERENT

Most budget planners are either spreadsheets, printable templates, or subscription apps that store your financial life online.

Tallyn is different.

It is a local-first HTML budget app that opens in Chrome or Edge and works offline after setup. You get an app-style dashboard, bank CSV import, bill calendar, debt payoff tools, savings goals, net worth tracking, and privacy-first local storage — all in one purchase.

Use it if you want a cleaner alternative to Google Sheets, Excel, Mint-style apps, or monthly budgeting subscriptions.
