CrewNerd turns your cell phone into an on-the-water training tool in any rowing shell, canoe, kayak or dragon boat - with no wiring! With a waterproof case, you can get real-time data of your workout. Using the accelerometer in your device, CrewNerd is able to accurately calculate your stroke rate as well as how much bounce (vertical movement) and stern check you are producing. Speed, pace and distance are calculated via GPS. ✓ Configurable display Add or remove rows in the main display screen. Each row can hold either one or two data items chosen from the following: • Stroke rate • Elapsed time • Distance • Speed or pace • Average speed or pace • Heart rate • Stroke count • Interval count • Meters per stroke • Check • Bounce • Course (direction) • Time of day ✓ Custom workouts Select from one of the provided workouts, or create your own based on distance, time or strokes. An auto-start feature starts the timer when the first stroke is taken, or you can set a “countdown” of 15 or 30 seconds before the timer starts to allow you to build up speed before starting a piece. ✓ Review your data All workout data is recorded and can be reviewed on the device or exported for use with compatible desktop applications and web sites. Supported export formats: GPX, KML, TCX, and CSV. You can view a map of your workout or export your workout data to SkyDrive or DropBox. ✓ Heart rate SpeedCoach Mobile supports two options for heart rate monitoring including: the 60beat.com adapter for older Polar straps, and the Zephyr HxM BT Bluetooth chest strap. Note: there appear to be compatibility issues when using the 60beat receiver with the Nokia 920, and possibly other Nokia phones. The 60beat product has been tested with the HTC 8X and works correctly there.
