About this app

Kasa is a fast, private expense tracker that works without an account or an internet connection. Add income and expenses in three taps, see where your money goes each month, and keep everything on your own device.

Why people choose Kasa
• Works offline — from first launch, no sign-up, no bank connection
• Fast entry — amount, category, done
• Totals a receipt as you type: 12.50 + 8 + 3, right on the keypad
• Calendar view — see which days cost you and which did not
• Unlimited categories and subcategories
• Recurring income and expenses, with a reminder on the day
• Several accounts, and transfers between them
• Multi-currency with your own exchange rates
• Reports for the month and for the last 6 or 12 months, by category
• Ten languages, including yours
• CSV export and import — your data is yours
• Dark mode, and a PIN or biometric lock on the app

Free, and it stays free
A banner at the bottom of the home, transactions and calendar screens is how Kasa is paid for. There is no subscription, no premium tier and no paywall, and no feature is taken away later. No advert ever interrupts you: none while you are entering a transaction, and the only full-screen one is the one you ask for. Tap No ads at the top of the home screen, watch one short video, and the banner stays away until midnight. Nothing is unlocked by it, and nothing is withheld without it.

Your data stays on your phone. No account, no server, nothing uploaded.
Track money offline: budget, income, expenses. No account, no subscription.
