This app started as something I built for my girlfriend. We'd tried plenty of expense and bill-splitting apps. They were either so fiddly we gave up after two days, or plastered with ads. What we wanted was simple: quick to use, easy on the eyes, no ads getting in the way. Most of all, we wanted to see at a glance where the money went this month and who paid more (honestly, it's saved us a few arguments). We spent a year on it, tweaking it every day — me building, her giving me grief — fixing anything that felt off until it finally felt right. If you're looking for a way to track shared money that isn't complicated, doesn't start fights, and that both of you actually want to open every day, I hope this helps. [Core features] • One shared ledger for two — log an expense and your partner sees it right away • Flexible splits: equal, custom ratio, "I paid for us", or private • 20+ currencies with automatic exchange rates • Separate projects, so travel and daily life don't get mixed up [AI logging] • Voice: say it out loud and it's logged • Snap a receipt and it reads the amount and items • Describe several expenses in one sentence and it splits them for you • Voice and receipt scan share a monthly AI quota [Cat companions] • 12 cat characters — pick one as your avatar • Each cat has its own character card and story; log more to unlock more • You and your partner each get a cat; at settlement they face off, so you see who owes whom [Stats] • Monthly spending charts to see where it's going • A category pie chart for a quick breakdown • Side-by-side contribution, so you both see who paid more • Export to CSV anytime [Easy settlement] • Works out who owes whom, and how much • Settle in one tap, with a clear repayment history • The settlement card shows who owes whom at a glance — no manual reconciling [Languages] 繁體中文, 简体中文, English, 日本語 [Subscriptions] Free: 1 project · 3 AI uses/month · 1 month of stats Plus: 10 projects · 100 AI uses/month · 6 months of stats · auto exchange rates · CSV export Pro: 200 projects · 200 AI uses/month · full stats history · everything unlocked [Subscription terms] • Plus: [local price] / month, or [local price] / year • Pro: [local price] / month, or [local price] / year • The subscription runs for 1 month or 1 year, depending on the plan you choose. • Payment is charged to your Apple Account at confirmation of purchase. • Subscriptions renew automatically. They renew unless auto-renew is turned off at least 24 hours before the current period ends; your account is charged for the next period within 24 hours before the current one ends. • You can manage or cancel anytime in Settings on your device, under your Apple Account → Subscriptions. • One subscribes, two use: once the ledger owner subscribes, the other member of the ledger is unlocked too — no need to pay twice.
