Kakeibo is a simple expense tracker built around one idea: the fastest possible way to write down what you just spent. The perfect ledger is the one you never keep. So this app puts everything into speed. Type the amount, swipe to a category, save. A few seconds — done before it starts to feel like a chore. That is why it lasts. ◆ Fast. Number pad for the amount, a swipe for the category, a tap to save. The part of any household ledger people give up on — the typing — is cut down to the fewest moves we could find.Forgot to log something yesterday? Add it for that date directly, without going through History. ◆ Quiet. One small banner at the top, and nothing else competing for your attention. No decoration to get through, no setup to finish. It is meant to feel like a stock iOS app you can open every day without getting tired of it. ◆ Clear. • Chart, calendar and list views of the month you are in • A monthly budget that tells you when you are drifting, without nagging • Home Screen and Lock Screen widgets, so you can check without opening the app • 30 currencies with daily reference rates from the European Central Bank • A gentle reminder so the habit survives a busy day ◆ Portable. Import a CSV from another budgeting app or a spreadsheet, review every column before anything is saved, and export your own records whenever you want. Your data is yours to take with you. ◆ Yours to shape. (Premium — a one-time purchase) Save the expenses you log again and again and record one with a single tap. Rename, reorder and re-icon your categories. Register rent and subscriptions once and let them catch up when you open the app. Split a bill and record only your share. Tag spending inside a category, keep household and work apart with separate wallets, and read a monthly report of where it all went. Ads disappear too. There is no monthly or yearly charge.Record straight from the widget with a keypad and category buttons, see the month laid out by day on a calendar widget, and choose which categories appear on it — independent from the category order in the app. Tags can be edited after the fact and used to search and filter your history. Recording, CSV import and export, widgets and search stay free. ◆ Private. Everything you record stays on your device. No account, no sign-in, no server of ours to send it to. (The only outbound request is to the European Central Bank's public exchange-rate file, and only when you convert currencies.) A household ledger is not something to be good at. It is something to keep. Start by simply knowing what you spent. Kakeibo is free to use. The free version shows ads. This app helps you record spending. It does not provide financial, investment, tax, accounting or legal advice.

Say goodbye to "I'll log it later." Consistency comes naturally when it’s this easy. ◆ Widget Entry Type the amount right into the widget numpad. No app launches, no loading screens, no transitions. Log your spending the exact second it happens. ◆ Fixed Expenses Rent, subscriptions, utilities—register your recurring expenses once, and they’ll be automatically tracked every month. Free yourself from repetitive manual entries. ◆ Calendar View See exactly how much you spent and when with our clean calendar layout. Review your high-spending days and "no-spend days" at a single glance. ◆ Flexible Budgeting Set custom budgets by month, by category, daily, or for specific custom periods. Perfect for tracking travel expenses or holiday events with a dedicated timeline! ◆ PDF & CSV Export Export your data into PDF or CSV formats.

The app is purely designed to do two things flawlessly: log lightning-fast and review effortlessly. Perfect for anyone who: ・Gives up on budgeting because logging is too tedious. ・Procrastinates entering expenses and forgets them entirely. ・Has struggled to keep up with traditional finance apps. ・Wants to record purchases on the spot, instantly. ・Wants a clear overview of monthly expenses, including fixed bills.

Verdict
The clearest difference is ads: 1s Expense at none against Kakeibo's shown. Kakeibo's advantage is iOS requirement (17.0 vs 26.5). On price, in-app purchases and device support there is nothing between them.
