## What is Wattbeat?

Matrix ICR50 (ICR-50) or Basic-Fit Smart Bike? See live cycling data and save your rides on iPhone. Tested with the Basic-Fit Smart Bike (Matrix ICR-BF); Matrix ICR50 has not been separately tested.

Wattbeat puts your bike’s power, cadence, speed, distance, energy and bike time on a clear, focused dashboard. Your bike. Your data. Your pace.

• Explore interactive time charts of power, speed, cadence and, when recorded, heart rate and resistance. Hold and slide, or tap for full screen.
• See power move with your cadence and keep your maximum in view.
• Reconnect automatically to your remembered bike and heart rate sensor.
• Add a compatible Bluetooth heart rate sensor.
• Record rides locally and share your measurements as CSV.
• Forward real bike power to a compatible watch or bike computer as Wattbeat Power.
• Explore a clearly labelled demo without equipment.
• Use Wattbeat in English or Dutch.

Your own interval timer
Save custom timers with optional warm-up and cool-down, hard efforts and light recovery between repetitions. Follow the countdown, rounds and progress in Your ride, in portrait or landscape. Four countdown beeps and spoken phase cues guide each change; confetti celebrates the finish. You control the resistance.

Turn on Use my watch once. Wattbeat remembers your choice, starts broadcasting when new real bike power arrives and stops when you disconnect the bike. Keep Wattbeat open and check that the receiving device displays and saves the watts.

Your ride in Garmin Connect and Strava
Record bike power on a compatible Garmin watch, then review the saved activity in Garmin Connect. When Garmin Connect is linked to Strava, the activity can sync with its recorded power. Wattbeat does not pair directly with or upload to Strava. Advanced Strava analysis may require a separate subscription.

Which indoor bikes work?
• Tested hardware: Basic-Fit Smart Bike, model Matrix ICR-BF. Check the model label on your bike.
• Matrix ICR50 (ICR-50): the manufacturer specifies Bluetooth FTMS. This model has not been tested separately with Wattbeat; check for live Indoor Bike Data on your exact bike.
• Other indoor bikes: designed for Bluetooth FTMS with live Indoor Bike Data; these models have not been individually verified.
• A Basic-Fit or Matrix logo alone does not establish compatibility. Bikes in gyms and other models may use different connections.

Equipment requirements
Your bike must provide Bluetooth Fitness Machine Service (FTMS) with live Indoor Bike Data. A separate heart rate sensor must provide the standard Bluetooth Heart Rate Service. Receiving devices must support external Bluetooth Cycling Power sensors. Bluetooth phone syncing alone is not enough. ANT+ only devices cannot connect directly to Wattbeat. Available measurements, pairing steps and simultaneous connections vary by equipment; compatibility is not guaranteed for every model.

Speed and distance use metric units. On recognised JOHNSON Q24 firmware, Wattbeat learns intermediate power steps from cadence and resistance. This smooths reported steps without calibrating absolute watts. Other bikes and insufficient or invalid data retain original watts. Wattbeat does not control resistance. Calories are the bike’s estimate. A dash means no recent measurement has arrived. Only power is forwarded to a watch; other sensors can connect directly to that watch where supported.

Your recordings stay on your iPhone unless you choose to share them. No Wattbeat account, ads, subscriptions or in-app purchases. Keep the app open while riding; test background operation and reconnection with your equipment.

Wattbeat is an independent app, not affiliated with, endorsed by or sponsored by Basic-Fit, Matrix, Garmin or Strava. Brand and model names identify equipment and services only.
