Smart Trainer Control

Bluetooth FTMS connectivity to control resistance on your smart trainer in real-time. ERG mode for structured workouts, simulation mode for GPX routes and free rides.

GPX Route Simulation

Ride real-world routes from GPX files. Your trainer responds to elevation changes with realistic grade resistance and surface types. Feel every climb and descent.

Outdoor GPS Rides

Take structured workouts outside with GPS tracking and audio coaching on iPhone. Or start a free ride and just pedal. Battery-smart GPS adjusts accuracy based on speed.

Training Plans

Follow periodized training plans with a calendar view. Plans adapt automatically when you miss workouts or need adjustments. Track completion and stay on schedule.

FTP Testing

Three built-in protocols — ramp test, 20-minute test, and 8-minute test — with automatic FTP detection. Your power zones update instantly.

Apple Watch

Pair your Apple Watch for live heart rate delivery to your iPhone during indoor rides — no chest strap needed. Haptic coaching alerts keep you in the zone.

Multi-Athlete Support

Individual profiles with separate FTP, power zones, workout histories, training plans, and platform connections for each athlete. Switch profiles instantly.

iCloud Sync

Ride history, workouts, training plans, and athlete profiles sync across your Mac, iPhone, iPad, and Apple TV via iCloud. Start a plan on one device, ride on another.
