For iPhone & Apple Watch
OneTwo Bike records your trip, whether it is a fast loop on your road bike, a trail on your mountain bike or a relaxed ride on your e-bike. Every sport brings its own metrics, its own auto-pause and its own speedometer range. No subscription, no account, no ads.
A simulated bike ride that runs entirely in your browser. Route, speed, elevation and heart rate are made up, no location is requested. In the app the values come from GPS, the barometer and Apple Watch.
Pick a bike and press and hold Start. In the demo time runs 30 times faster. The speedometer range and auto-pause change with the sport. Tiles and values are simplified in the demo.
No photos yet. Tap the camera while riding.
The first entries are examples. Rides you save from the simulator appear at the top and stay in this browser only.
Tick off what you have done. Your progress stays in this browser only.
A workflow that fits the handlebars.
Road bike, mountain bike or e-bike. Each has its own metrics, its own auto-pause and its own speedometer range.
Press and hold Start. Recording keeps going with the screen locked and is restored after a crash.
Speedometer, live map with elevation profile, photos along the route, voice announcements and live stats on Apple Watch.
Everything lands in Activities. Optionally as a cycling workout in Apple Health, synced through iCloud or exported as a GPX file.
Every sport has its own metrics, its own auto-pause and its own speedometer range.
Elevation uses your iPhone’s barometer, which makes it more precise than GPS alone. The app filters out position jumps and speed spikes.
The live map shows your track while you ride. Afterwards every ride gets a route image colored by speed.
The map follows you and rotates with you, or shows north up or the whole route.
Fold out the elevation profile right below the map.
The route image of every ride shows where you were fast and where slow.
As a bar chart in the detail view, with map, elevation profile and heart rate chart.
All rides grouped by day or sport, sortable, with tags, color tags, filters and search.
The map needs an internet connection to load new areas. There are no offline maps and no navigation.
Take photos on the way with the built-in camera without leaving the recording. Flash, zoom, camera switching and self-timer are included.
Listen instead of looking, press and hold instead of tap: OneTwo Bike is made for rides where your phone stays in your pocket.
Version 1.0 comes for iPhone (iOS 18 or later) and Apple Watch (watchOS 11 or later), not for iPad or Mac. Heart rate requires an Apple Watch or another device that shares its data with Apple Health.
With iCloud your rides and photos are on all your devices. If there is a conflict, you decide. Try it:
Evening ride Tag: Training
Sunday tour Tag: Tour
OneTwo Bike reads your heart rate from Apple Health and, if you want, saves rides there as cycling workouts.
Your rides live on your iPhone and, if you turn it on, in your private iCloud.
Heart rate data always stays on the device. It is never synced to iCloud, exported or shared with third parties.
No ads, no tracking, no server of ours.
The app only asks for “While Using the App”, never “Always”. Recording only starts when you start it.
Optional sync uses your private iCloud database only.
Everything else is in the privacy policy.
