Built for serious training

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.

Enduro Mode

Alternating liaison and stage laps with a countdown into each stage, on iPhone and Apple Watch. Per-lap stats, route and elevation colored by stage, and uploads to Strava as a mountain bike ride.

Adaptive Training Intelligence

A daily training suggestion tailored to your form, training history, and race calendar. Built-in coaching explains every recommendation in plain language, phrased by Apple Intelligence on supported devices. A 4-week outlook shows the shape of your training as it adapts to each completed ride.

Power Profile

Your power-duration curve builds from the rides you already do — no test protocol required. See critical power, your rider phenotype, and which duration band matters most for the discipline you race. Capability tracking follows your punch, climbing, durability and efficiency over time, and a progression block commits to moving one of them.

Race Calendar

Plan your season with an enhanced race calendar. Track goals, registration status, and event URLs. Import GPX courses to preview the route, simulate it indoors, or ride it outdoors. Post-race results link to your completed ride automatically.

Training Trips

Multi-day trips, camps, and destination riding get their own place on the calendar. Your plan tapers into the trip and recovers out of it, and the coaching switches to companion mode for the days you're there. Mark a trip as a primary goal and the build ramps toward it.

FTP Testing

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

Ride Analysis

Every ride gets per-second charts for power, heart rate, cadence and speed, a route map, and lap breakdowns. Power distribution shows where your watts actually lived; peak power shows your best effort at every duration against your 90-day best. Descent load and late-ride fade are surfaced for gravity rides.

Apple Watch

Ride standalone on your Apple Watch with GPS, power, and cadence — sensors pair through watchOS Settings. Digital Crown cycles your metric roller. Five ride pages including live power, lap stats, averages, and map. Or keep it as a companion for heart rate and haptic coaching during iPhone rides.

Wet Mode

Rain on a touchscreen registers as taps — enough of it can end a ride by itself. Arm Wet Mode before a wet ride and the Watch screen goes fully dead using native Water Lock. Press and hold the Digital Crown to unlock.

Apple TV

Full rides on the big screen. Structured workouts, GPX routes, and free rides with trainer control, plus your ride history and stats — all on Apple TV.

Multi-Athlete Support

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

iCloud Sync

Ride history, workouts, race calendar, and athlete profiles sync across your Mac, iPhone, iPad, and Apple TV via iCloud. Plan on one device, ride on another.

Workout Library

Stock templates for endurance, sweet spot, threshold, VO2max, and more. Create custom workouts with the built-in editor or import ZWO and MRC files.
