Simple. Clear. Transparent.
We're students who got tired of finance apps looking like 2009. Luke is what we wished existed.
We get the broke phase in life. Rent, Spotify, going out, saving up. Luke is built around your actual life — not some textbook budget.
The fastest expense tracker ever built for mobile. Log a €3.50 coffee before you finish paying. No menus, no categories, no nonsense.
No selling your data to banks or advertisers. LUKE is built on privacy-first principles. What you spend is your business.
Whether you're in Zürich, Vienna, or Los Angeles — Luke supports your currency and your lifestyle. No borders on good budgeting.
Log any expense faster than you can say "I'm broke." Amount → Category → Done. Seriously, that's it.
Every expense logged, every budget hit, every streak kept earns XP. Turn saving into a game you actually want to play.
Smart weekly and monthly insights show exactly where your money goes. No surprises when the month ends.
We turned the most boring part of adulting into something you'll actually open every day.
