Five currencies, one brain… and a simple idea turned into an app.
What started as frustration over complex currency apps became a weekend project - now a sleek, ad-free converter built with ExpressJS, MongoDB, and React Native. Simplicity done right.

Travel enough and you’ll know the struggle: five currencies in one week, one tired brain trying to decide if that coffee is a treat or a financial mistake.
Existing apps promised simplicity — then hit with ads, subscriptions, and UX puzzles so twisted even Rubik would complain his cube was too easy.
So, two Saturday mornings later, I decided to build something better. A currency converter that just… converts. Fast, accurate, and clean.
No ads. No subscriptions. No nonsense. Just one rate to understand the real value of your money — even offline.
Under the hood, it runs on ExpressJS (API), MongoDB (data), and React Native (mobile). I’d have gone with Swift, but some folks still prefer to risk their security and use Android.
Built for travelers, remote workers, and anyone tired of unnecessary complexity. Because, as Da Vinci said — “Simplicity is the ultimate sophistication.”
Download it on the App Store. It won’t change your life, but it might change how you buy coffee abroad. ☕Michal
