What we make
Apps with a narrow job and no ambition to become your whole life. Costia Finance for money you spend and share, Costia Training for the gym — and more to come, each with the same account behind it.
About
Small apps that do one job properly.
Costia began with one app, for the money you spend and share. It is becoming a family: focused apps for the things people do every week, sharing one account, one subscription and one set of principles.
How we use AI
Where it removes typing, never where it removes judgement. It fills in what it read, proposes what it would do and waits for you. When a number matters — a debt, a load on the bar — arithmetic you can check decides it.
How we make money
From one subscription, and only from that. No ads, no data sold, no trackers. The free tier of each app is complete; Premium pays for the part that costs us to run.
Where we are going
Costia is independent and early. The plan is a few more apps, each earning its place, and one account that makes the whole family feel like one product.
