Kuma
Read full descriptionHide full description
Kuma is a small, clumsy, warm bear who turns one sentence into a precise expense record. Tell Kuma what you spent by voice or text, the way you would tell a friend: "lunch at blue bottle for $4" "32 on gas" "got 40 back from Sarah" Kuma files the amount, merchant, and category in your ledger, then says something kind back with one original sticker. WHY A BEAR Most expense trackers begin with a bank password and a dashboard. Kuma begins with one sentence. The bet is simple: bookkeeping is easier to keep doing when it feels warm instead of judgmental. Kuma is clumsy in manner and precise in work. The bear is a bit of a mess. The numbers never are. WHAT IT IS LIKE - No bank login needed. Nothing to connect before you start. - Type one line, or tap the microphone and speak it. Apple turns your voice into editable text; Kuma does not store the audio. - Kuma confirms the amount and category and replies with one original sticker. - Correct an entry from Chat or Ledger when something needs fixing. - Ask "how much on coffee this month?" Totals come from your ledger, not a guess. - Track money out and money in in the same book. WHAT YOU GET - A clean, filterable ledger. - Monthly spending by category. - Ranked spending, a calendar view, and six months of cash flow. - Account-currency and dark-mode controls. - Your ledger, charts, and correction tools on every plan. PLANS The Free plan includes 15 new entries each Monday-to-Monday Pacific week. Optional Kuma+ removes that weekly entry limit so Kuma can keep logging all week. Monthly and yearly auto-renewing choices and localized prices are shown before purchase. Manage or cancel through Apple. WHAT KUMA DOES NOT DO - Never shame you or tell you that you spent too much. Kuma notices. Kuma never advises. - No budgets, goals, streaks, or financial, investment, tax, or legal advice. Kuma keeps the record. What you do about it is yours. To understand a message, Kuma sends the text and limited recent conversation context to an AI provider. You can delete your Kuma account and its associated data from inside the app at any time. Kuma has an English interface. Each account uses one selected currency. Changing the currency never converts an amount.

Verdict
The clearest difference is ads: Kuma at none against Compound Interest Calc's shown. Kuma also leads on update cadence (every 2 weeks vs every 3 months). Compound Interest Calc's advantage is device support (3 vs 1). On price, in-app purchases and iOS requirement there is nothing between them.
