CASE STUDY // NATIVE iOS APPLICATION

COMPASS

A city guide and trip planner with routes, walks, and offline access.

Challenge

Make a city guide useful during a real trip, when people need more than hundreds of pins: a clear route, useful context, and a saved plan that remains available with unreliable connectivity.

Solution

We created a native SwiftUI/MapKit application with a local trip model, downloadable city packs, and cloud synchronization. Separate domains cover discovery, active walks, transport, accommodation, eSIM, weather, notifications, and offline access.

What we delivered

A signed release candidate, a live product website, and a content pipeline for 15 initial destinations across Russia.
