Native iOS apps, made with care.
Stationify Oy is a Helsinki-based studio building privacy-first iOS apps. SwiftUI, on-device intelligence, and the kind of polish that comes from caring about every detail.
Mission
Good apps are invisible, dependable, and honest.
Too much software is built to impress rather than to serve. We take the opposite approach. Every app starts with the problem, not the tooling. We write code that ships, that runs well on the user's device, and that will still feel right two iOS versions from now.
Native, fast, and considered. Every interaction is one we'd want to use ourselves. Every screen is one we'd be happy to ship.
We believe people own their data. Not the platform, not the vendor — the people who created it. Every app we build starts from that principle. Your privacy is our policy, not the other way around.
What we do
iOS apps, end to end.
02
On-device intelligence
Apple Intelligence, Core ML, and the Foundation Models framework. Insights, anomaly detection, and natural-language coaching — all running locally, never in the cloud.
03
Privacy by design
No accounts, no analytics SDKs, no tracking. HealthKit, Keychain, and SwiftData with proper file protection. The data stays where it belongs — on the device.

About
A small studio in Helsinki, building iOS apps that respect their users.
Stationify Oy is based in Helsinki, Finland. We design and build native iOS and watchOS apps from concept to App Store. Every app gets senior attention from start to finish — no juniors learning on your project, no stack rotations halfway through.
We work best with people who care about quality and want a partner who will tell them the truth. If something does not need to be built, we will say so. If the real problem is somewhere else, we will point there first.
