About this app

Outflow — a simple, private expense tracker you can easily make your own.

Your data stays on your device. No account, no sign-in, no server. Your money is your business.

Highlights
• Works offline — tracking never needs a connection
• No ads, no tracking, no data collection
• Small, light, and fast to open
• Back up & restore as a file — move to a new phone anytime

Track your spending
• Quick entry with categories and subcategories
• Recurring and fixed monthly expenses
• Monthly / quarterly / yearly / all-time summaries
• Charts by category and over time; filter by category

Make it yours
• Themes, accent colors, fonts
• App backgrounds — patterns or your own photo
• Number & date formats, currency
• Adjustable spacing, default screen, and much more

Outflow Pro — one purchase, not a subscription
Everything above is free. One optional purchase unlocks unlimited categories, monthly variable expenses, per-category charts, every currency, and custom themes, backgrounds and number formats. New installs get 7 days of Pro to try it out. Purchases are handled by Google Play — that check is the only time the app goes online, and it never sends your expense data.
Track expenses the easy way — offline, make it yours, fully private.
