Description by Klaas Wumkes Written by the developer, not by AppBrain. Click to read.
An app for phases. Not for life.

Mark works differently from most finance apps. You open it when your spending feels off. Write down what you spend for a week or two. Become aware as you go. Then put it away until you need it again.

No bank sync. No subscription. No push notifications. No background tracking. Mark does nothing unless you open it.

Just you, an amount and a word. That's all it takes.

WHY IT WORKS

Knowing you have to write it down already changes what you spend. You're not forced — you become attentive. That's the whole mechanism. Mark doesn't measure anything. You observe yourself, with Mark as the notebook in your hand.

Mark sits in the tradition of Mindful Money: less measuring, more noticing. Making it visible changes things.

THE THREE SECTIONS

· Today — one number per day, a list of your entries. What did you spend today. Nothing more.

· All — what you spend on average per day, extrapolated to the month. You see, day by day, what adds up.

· Wishlist — what you want to buy waits at least a week. Not every wish lasts that long. Some disappear on their own. What stays was actually meant.

WHAT MARK DOESN'T DO

Mark doesn't measure. Mark doesn't track. Mark doesn't categorise. Mark doesn't connect to any bank account. Mark doesn't send push notifications. Mark doesn't reward you with streaks or points. Mark doesn't tell you what you're doing wrong.

None of that is missing — it's intentional. Other apps want you daily. Mark wants you to understand when you need it, and when you don't.

EXCEPTIONS

Not every expense is everyday. A birthday gift, a repair, a utility bill — you can mark those as exceptions. They show up in your list but don't count toward your daily average. So the extrapolation stays honest.

LIGHT, DARK, OR SYSTEM

Mark matches your display. Light, dark, or follows your system setting. Pick what you want.

YOUR DATA

Your data stays on your phone. Nowhere else. No account, no cloud, no server. Delete everything with one tap, anytime. It's yours.

BUY ONCE, KEEP

Mark costs £6.99. Once. No subscription. No in-app purchases. Updates are free.

Mark is a tool. You don't subscribe to tools — you own them.

WHO'S BEHIND IT

Mark is made by the same studio that built Studjur, the grade calculator for German law students, running since 2022. We build small apps that do one thing well. Mark is the second.
