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 during your workout and even relay it to your coach.

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

In landscape mode there are up to six configurable data fields, and in portrait mode there are up to ten. Choose from the following:
• Stroke rate
• Elapsed time
• Distance
• Speed or pace
• Average speed or pace
• Heart rate
• Stroke count
• Interval count
• Meters per stroke
• Total distance
• Projected time and distance
• Check
• Bounce
• Course (direction)
• Time of day

Set the top line to be double-height to make the most important data stand out. In portrait mode, the top two lines can both be made double-height.

• 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.

• Custom courses

Create custom by plotting your start and finish lines on a map. The application will start the timer automatically when you cross the start line and stop when you reach the finish. This is great for hands free operation in long distance races or for set routes you routinely use.

• 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 view an interval data chart with configurable distance markers showing split times on your phone.

• Heart rate

CrewNerd supports all Bluetooth Smart heart rate monitors.

• Live position tracking

Stream your workout data as it happens to any web browser via CrewNerd.com.

• VoiceOver support

For blind and vision-impaired athletes, CrewNerd provides audible feedback during your workouts. Configure the content and timing of the announcements to meet your needs.

• For coaches

Use custom workouts to keep your practices on target. In coach mode, you can tap anywhere on the screen to check stroke rate. CrewNerd can also be used on the iPad for a larger display.

Waterproof cases are available to protect your iPhone on the water. See our web site for more information.

Gebruik tijdens roeitrainingen

RV Hemus

De speedcoach applicatie werkt erg goed tijdens het roeien. Het display is goed leesbaar. Ook door de waterdichte hoes die we met klitteband in de boot hebben bevestigd blijft het display goed zichtbaar. Bij de ingestelde workouts is de piep goed hoorbaar na een interval. Het is wel jammer dat de gps bij bewolkt weer onnauwkeurig werkt. Ook is de snelheid niet af te lezen in de boot maar pas achteraf. De facebooksoftware mag nog wel iets uitgebreider en de uploads zouden gratis moeten zijn. De batterij van de iphone gaat vrij snel leeg, 3 uur max.

Het is een leuke vervanging voor de 'echte' meter, maar die is toch net effe beter.

Goed werkende row app


Al heel wat verbaasde roeiblikken gehad! Werkt erg goed! Slagen per minuut en afstand werken goed. De 500m tijden zijn niet heel accuraat en wisselen nog wel eens. Met de Head gebruikt als tempoteller en werkte erg fijn. Voordeel is dat de tijd automatisch stopt als je stil ligt en automatisch start als je weer gaat roeien.



Super app, werkt goed, geeft goed overzicht en goed in te stellen. Klein min-puntje geen total op app zelf, wel na export, maar niet op app.
