About Motum
A workout tracker that respects your data, your battery, and your time.
The story
Motum started as a side project — a workout app for someone who'd cycled with Strava, Garmin Connect, and Apple Fitness, and wanted something different. Less social, less marketing, more honest data. No accounts. No ads. No premium tier teasing features behind a paywall.
It's built by a father-daughter team in Sofia, Bulgaria, with care for the details that matter to people who actually use this kind of app: live climb detection that works without pre-loaded routes, per-activity recording layouts you can customize, an Apple Watch companion that doesn't just mirror the phone, and a power estimation model for cyclists who don't have a power meter on their bike.
What Motum believes
Your data is yours
No accounts. No email collection. Activities stay on your device. Health data never leaves your phone. The only thing we collect is an anonymous installation ID so we can see crash reports.
Built for the platform
Native SwiftUI, native SwiftData, native HealthKit. Live Activities, widgets, the Dynamic Island — Motum uses what Apple gives us, the way Apple intended.
Real engineering, not features
ClimbPro detects climbs from your GPS stream in real time. The power model accounts for surface and riding position. Auto-pause uses the GPS loop, not a timer. Details matter.
