Vurio
Vurio plans motorcycle rides and then guides you through them. You say how much time you have and get back a loop worth riding — curvy, with elevation, and without doubling back. One person built all of it, from the first commit to the store release.

React Native cannot drive turn-by-turn navigation
This is not about performance — there is simply no way in. Navigation has to run with the screen off and the phone in a pocket, speak over a locked display and recalculate when the rider takes a different turn. All of that lives in the native layer, out of reach from JavaScript. The answer was our own modules in Swift and Kotlin over the Mapbox Navigation SDK v3. The hard part was not writing them but keeping both platforms behind one shared contract — when the behaviour diverges, you find out from someone doing 80 km/h.
Measured, not generated
A model may propose a route, but it does not get to claim what the route is like. Curvature, elevation and self-overlap are computed from real road geometry over a self-hosted GraphHopper and OpenStreetMap data. A route that fails the quality bar never reaches the user — even if that means generating nothing at all. It is an uncomfortable rule, and it is the only way the promise holds.
Shipping is part of the work
Between a finished app and an app in the store sit several weeks that cannot be estimated up front: review, privacy declarations, store assets, background location permissions and behaviour that has to pass on both platforms. That part of a project is routinely underestimated — on Vurio it was planned in from the start.
Vurio shipped to the App Store and Google Play with more than a thousand people on the waitlist and first place at BuilderDay 2026. For the studio it is proof that cannot be borrowed from someone else's work: a complete mobile product taken from zero to the store, native layer included.
- Native modules in Swift and Kotlin over the Mapbox Navigation SDK v3, both platforms behind one shared contract
- Self-hosted GraphHopper over OSM data — curvature, elevation and self-overlap measured from real road geometry
- Voice guidance keeps running with the screen off and the app in the background, verified on both platforms
- Around 1,400 commits · 1st place at BuilderDay 2026 · over 1,000 people on the waitlist
