Every feature is free. ■ Fast entry • Amount → note → category, without leaving the keyboard • Autocomplete from past entries: tap "Starbucks · Cafe" to save instantly • Notes you use often appear in faded text as you type • Pin your go-to categories to the front • Optional one-tap save when you pick a category • Home Screen and Lock Screen widgets open the entry screen in one tap • iOS 18 or later: add it to Control Center and the Lock Screen buttons too ■ Stats at a glance • This month's spending, income, and what's left • Spending by category, with fixed and variable costs • A yearly table for the big picture; tap a month to open it • Swipe to move between months and years ■ Search • Search by note, category, amount, or date • Natural dates like "September" or "yesterday" ■ Add-ons (free, turn on only what you need) Turn them on in Settings → Features → Add-ons. They start off so the app stays simple, and turning one off never deletes your records. Split • When you pay for everyone, what friends pay you back comes off your spending • Type the amount and tap "Split" above the keyboard to divide it evenly • Check people off as they pay. Once everyone has, only your share counts • Paybacks come off the month you paid, so that month stays accurate • See what you're still owed in a banner at the top of your list Tags • Group spending across categories, like a trip, and see its total • Turn on "Keep adding" and every new expense on the trip gets the tag • Tagged spending still counts in its own category • See totals by tag in your stats ■ Your data stays on your phone • No account, no login • No network access, no ads, no tracking • No paid features, no subscription • Included in your iCloud device backup • Export and import to move to a new device ■ Also • Light and dark mode • English and Korean • Won, dollar, euro, yen, and yuan • Add categories and edit their names, icons, and colors
