eXpense is the simplest expense tracker for cash spending — designed for people who want effortless tracking without categories, accounts, or complex budget setup. Open the app, type the amount, tap save. eXpense logs your spending in seconds, so you always know where your money goes. No sign-ups, no bank linking, no learning curve, no nagging upsells. HOW IT WORKS Three taps and you are done. Enter the amount, optionally add a one-line note, save. eXpense focuses on the daily habit of logging — the part every other expense tracker app gets wrong by demanding too much friction up front. The whole interaction takes five seconds. Do it at the till, do it on the bus, do it on your watch. WHO IS THIS FOR - People who pay in cash and want to see real spending - Travelers tracking daily costs without categories - Couples splitting expenses without arguments - Freelancers logging billable cash purchases - Anyone burned out by complex personal finance and budget apps KEY FEATURES - One-screen entry: amount, optional note, save - Daily, weekly, and monthly totals at a glance - Apple Watch app for instant logging on the wrist - Home Screen and Lock Screen widgets — see today's spend without opening the app - iCloud sync across iPhone, iPad, and Mac - Dark mode and large-type support - Full export to CSV for spreadsheets and accountants - Multi-currency support for travel and digital nomads - Optional Face ID and Touch ID lock for the whole app PRIVACY BY DESIGN Your data stays on your device or in your private iCloud — never on our servers. No analytics on your transactions. No ads. No bank connections. No third-party trackers. eXpense is a personal finance app that respects your privacy because spending data is nobody's business but yours. DESIGNED FOR DAILY USE Most expense trackers fail because they ask too much: pick a category, choose an account, tag a payee, link a card. By the third day you stop logging. eXpense is built around the only metric that matters — did you log today, yes or no. Open the widget, see your daily total, decide tomorrow's spending in five seconds. WORKS EVERYWHERE - iPhone with watchOS Apple Watch companion - iPad with side-by-side multitasking - Mac via Apple Silicon with full keyboard shortcuts - Widgets on iOS, iPadOS, and macOS Home Screen - Apple Watch complication on every face NO SUBSCRIPTION NONSENSE One-time purchase. No subscription. No paywalls between you and the basic feature of writing down what you spent today. The app you buy today is the app you have forever — with free updates as new iOS, iPadOS, and watchOS versions ship. WHAT USERS SAY "Finally an expense tracker I actually use." "Three taps, done. Why is this so hard for everyone else?" "The Apple Watch complication is the killer feature." "I tried five budget apps before this. eXpense stuck because it asks for nothing." REQUIREMENTS iOS 17.0 or later, iPadOS 17.0 or later, macOS 14.0 or later, watchOS 10.0 or later.
