MARK is the finance app you’ll actually use because it doesn't ask much of you. Apps should help, not be a burden. That's the philosophy behind MARK.
MARK adapts to your life. If you simply want an overview of your income and expenses, you can turn off budget mode and log your income and expenses whenever you feel like it. That's all it takes to stay on top of your finances.
If you notice your spending is getting out of hand, you can turn on budget mode, set a limit, and see exactly how much you can spend each day to stay on track.
MARK delivers signal, not noise. In the end, only two questions matter: How much is left at the end of the month? And in budget mode: Am I still on track or have I overspent? That's what MARK focuses on. There are no colorful pie charts, no category-level budget plans, no endless statistics about your spending behavior over the last twelve months. No feature you never use but see every single day.
Just the numbers that actually matter — clear and without distraction.
FEATURES
Optional categories: You can completely disable categories for income and expenses if all you care about is the bottom line.
Forecasts: Get a realistic projection for your month and your year.
Intuitive overview: Swipe seamlessly from month to month or year to year to compare your finances side by side.
Recurring entries: Log regular income and expenses once — they'll be accounted for automatically.
Reserved function: Log unexpected expenses as "reserved." They're recorded without affecting your calculated daily budget.
Batch entries: Log all expenses from a day, a week, or a month in a single entry — using the built-in calculator. The amount is automatically distributed across the time period, so you don't have to log every expense individually.
Privacy screen: Hide your amounts with a single tap on the eye icon.
Detailed comparison: Compare not just your expenses, but also your income and overall result with the previous month or year.
Currencies: MARK works worldwide with currencies like EUR, USD, CHF, and many more.
True privacy: Your data belongs to you. There's no cloud and no server. Everything stays on your iPhone.
No account. No tracking. Just your finances.
