Description
 
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.

NOTE: CrewNerd Lite works exactly like the full version but is limited to 100 strokes or 5 minutes of use each time you run the application. In CrewNerd Lite, you also have the option of eliminating the trial mode restrictions by purchasing a 30-day subscription which can be renewed indefinitely.

• 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.

SSRCGigrower, 5 stars:

Excellent rowing app. I race Cornish Pilot Gigs (crew of 6 plus cox) and I was worried it would not work so well as it does on sliding seat boats as the gigs dont have such a pronounced catch. By lowering the sensitivity setting I managed to get it to register each catch accurately and it has now become an excellent tool for club training. I have combined this app with a GoPro HD camera and DashWare software to calibrate the video with the SpeedCoach Mobile .csv logs to show real time speed, stroke rate, time and GPS location superimposed over the video. The app is expensive but considering the time put into the development and the relatively small market it is fairly priced. Strongly recommend downloading the free version to trial it first. Happy rowing....
