Kairoku - Expense Tracker

A simple expense tracker for logging spending the moment it happens. No bank or card linking, no receipt scanning, and no income tracking. Kairoku focuses on one thing: making it easy to keep recording. ■ One-tap presets Coffee, lunch, train. Pin your frequent expenses as presets at the top of Home. One tap finishes the entry—often before you leave the register. Mistakes undo in a moment. ■ Remaining budget front and center Set a monthly budget and Home shows how much you can still spend this month—large and clear. Seeing what’s left, not only what you’ve spent, makes pacing the second half of the month feel natural. Overspending shows plainly in red. ■ Fast manual entry For anything without a preset, enter the amount and pick a category. Amount chips (+100 / +500 / +1000) and your last category keep typing to a few seconds. Memo and date only when you need them. ■ Automatic totals Reports show category breakdowns and day-by-day trends in charts. Compare with the same day last month so you can answer “am I overspending?” right away. ■ Log from widgets Home Screen widgets show remaining budget and presets. Record directly from a widget button without opening the app. ■ Built to help you stick with it ・Optional daily reminder notifications (set any time) ・Add your own categories and rename them; hide ones you don’t use ・Light and Dark Mode ■ Peace of mind All records stay on your device. No account is required, and your expense logs are never sent off the device.
