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.

Ratings and Reviews
Step forward for rowers
Although still nervous about taking my phone onto the water, am happy with this although I haven't used it enough yet to comment in any depth. Would it be possible for the developers to consider pairing it to the Apple iwatch which is water proof? I would love that even if it was just for some of the key functions. Thank you.
I have been using CrewNerd for a few months now to confidently map, with accuracy, my training and performance improvements in K1 racing kayak.
I use an external HR monitor via bluetooth and run CrewNerd on my iPhone 6 (which has a really good built in GPS receiver).
The real-time feedback I get during training sessions has revolutionised my approach to the sport.
I have checked out many other Apps and systems but find that nothing else provides such a complete and versatile solution for water-sport athletes and coaches from all disciplines ranging from rowing to paddlesports.
CrewNerd has become an indispensable part of my equipment.
A great solution at a very reasonably price.
I have used this app for a couple of years now and find it invaluable. Whatever boat I'm in it gives excellent information and by simply emailing the outing data from the history button the whole crew can see where we were quickest on the course and hence what stroke rate was efficient. Using longitude and latitude of known points on the river (very easy to obtain from google) it is then easy to get very accurate timings between two points. The map showing your exact course taken is also spot on and shows very accurately where we hit fallen trees etc. The display can be adapted to your taste very easily to show speed, split time, distance, stroke rate etc. the only tweak I could wish for would be to plot our ideal course on the map and then have this app give 2 beeps for left and one beep for right - ie a navigation aid. A brilliant app all round - congratulations.
