For iPhone
Spend on purpose.
Portemonnaie isn't a budgeting app. Two quick questions per purchase show whether you spent intentionally or on impulse — privately, on your phone.
The method
Two questions. That's the whole method.
Did I need this?
Did I see it coming?
No categories, no tags, no rules to set up. Answering takes a few seconds, and that short pause is the point: every purchase becomes a conscious choice.
The Portemonnaie Matrix
Every purchase lands in one square.
Your two answers place each purchase in a 2×2 grid. One screen shows your whole month — not what you bought, but how you decided.
Essential
Needed and expected. Rent, utilities, groceries.
Planned
Wanted and expected. The trip you saved for, a dinner out.
Unavoidable
Needed, but a surprise. A car repair, a cracked phone screen.
Impulsive
Wanted, and a surprise. The real leaks in any budget.
Why not categories?
A pie chart won't tell you what to change.
Most finance apps tell you that 32% went to food and 18% to transport. You already knew you eat and commute.
Portemonnaie asks a better question: should you have? A €4 coffee and a €400 jacket can both be impulse buys, so both land in the red. Over a month, the matrix becomes a mirror. It doesn't judge you. It just shows you how you decided.
A look inside
Simple on purpose.
Private by design
Your spending is nobody's business. Not even mine.
Everything stays on your iPhone. No account, no cloud, no tracking, no ads. The app works fully offline, and I couldn't see your data even if I wanted to.
Want a backup? Export your full history as a plain JSON file to the Files app, whenever you like. It's readable, portable, and yours.
Why a subscription?
An app that teaches intentional spending can't be funded by impulse-driven advertising.
I'm Nándor, and I build Portemonnaie on my own. There are no ads and no data sales, so your subscription is what keeps it running.
Try it free for 7 days. After that it's €2.99 a month or €29.99 a year. If it stops one impulse buy a month, it has paid for itself.
