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
• Speed or pace
• Average speed or pace
• Heart rate
• Stroke count
• Interval count
• Meters per stroke
• Total distance
• Projected time and distance
• 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.
Fixed compatibility problems with recent firmware updates for the XPGS160 external GPS receiver.
Fixed a problem with the "Total Distance" field when Coach Mode is in use.
Ratings and Reviews
I started off with CrewNerd Lite to see if the app was worth the price. After a few rows, I opted into the full version of CrewNerd and was initially very impressed. I liked the support for my Polar H7, which coupled with the tailorable Row/Paddle page, allowed me to see my strokes per minute (SPM) and heart rate in BPM.
Unfortunately, the SPM and BPM are now working sporadically, which leads to a frustrating workout, especially when your coach is telling you to keep a specific SPM.
Requesting Apple Watch Functionality
4 years after my initial review, still a great app. Now that I have an apple watch I find myself wishing I could use apple watch functionalities with CrewNerd, this would be things like heart rate, workouts, distances, etc.
Needs Apple Watch remote
Great app, but almost impossible to use on the boat with a waterproof app. Stopped using it for now as I can get a cheaper app with watch remote.
