You can calculate your Distance, Time, Average Split, Weight Adjusted Scores, and Predictions using Paul’s Law. You can also view World Records and compare yourself against the best.
Weight adjustment uses the following formula from Concept 2:
Wf = [body weight in lbs / 270] raised to the power .222
Corrected time = Wf x actual time (seconds)
Corrected distance = actual distance / Wf
Paul's Law says that for a rowing athlete with balanced speed and endurance capabilities, for every doubling of distance the 500m split should increase by five seconds.

Attention: This App is not intended for use by individual users and coaches. If you're an individual rower, please check out our "Rowing in Motion - Solo" app. This App is intended for Clubs and professional rowing organisations and requires an Organisation account for the "Rowing in Motion Analytics" online service.
When linked to your organisation as a "Boat" device, the App measures and records boat acceleration, speed and stroke-rate using the device's GPS and Accelerometer. Live boat acceleration graphs and stroke metrics give you detailed feedback on how efficiently the crews moves the boat forward and where it can improve its rowing technique to row faster.
When linked to your organisation as a "Coach" device, the App allows coaches to view realtime data from another instance of the App running on a device in a rowing boat using a mobile WiFi (no internet connection required).
* Measures Strokerate, Speed, Distance and Boat Acceleration, giving you insight into all aspects of your stroke
* Full Screen Graphs: Showing your boat acceleration compared to an average of the previous strokes
* Customizable user interface: Display all the data you need to see to improve your rowing stroke
* Instantly upload and analyze your recorded rowing sessions with your Analytics account
* Stroke Analysis: Live average acceleration graphs, speed graph
* Sonification: Turn your boat acceleration into a sound for a better realtime feedback to help you improve the effectiveness of your stroke.
* Stroke Metrics: Stroke Metrics derived from boat acceleration allow you to easily focus on specific aspects of the stroke
* Dashboard for coaches that displays stroke-rate, speed and last typical stroke of boat devices in range. Connect to boats with a tap to view all realtime data.
* Supports Heartrate measurements using any Bluetooth Smart compatible Heartrate strap (requires Bluetooth 4.0)
Using the accelerometer in your phone or tablet, CrewNerd calculates 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. Heart rate monitoring is supported as well.
Use a pre-programmed workout (or create one of your own) or just start the timer and go. All of your workout data is recorded and can be viewed later in map or graph form, or exported in a variety of popular formats. Use our live tracking feature to let coaches and spectators monitor your race or workout in real time in most web browsers.
Note: CrewNerd runs in trial mode by default, giving you 100 strokes or five minutes to evaluate the application in your boat. A small monthly subscription fee removes these restrictions.
• Configurable display
CrewNerd's main screen is very configurable. Rows can be double-height and can display either one or two of the following data fields:
• Stroke rate
• Elapsed time
• Speed or pace
• Average speed or pace
• Projected time or distance
• Total practice distance
• Heart rate
• Stroke count
• Interval count
• Meters per stroke
• Course (direction)
• Time of day
• Maximum heart rate
• Maximum stroke rate
• 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 workouts can be created easily, much like programming a Concept 2 ergometer. Workout types include:
- Single distance
- Single time
- Distance intervals
- Time intervals
- Stroke intervals
- Custom intervals (any combination of distance, time, or stroke-based intervals)
• Custom courses
Create custom by plotting your start and finish lines in Google Earth. The application will start the timer automatically when you cross the start line and stop when you reach the finish. Great for hands free operation in head races or for set routes you routinely use.
• Review your data
Workout data is recorded and can be reviewed on the device in map, summary, or chart form. Data can also be exported for use with compatible desktop apps and web sites. Export formats include: GPX, KML, TCX, and CSV. The charting feature lets you select one or two data items to be graphed for each interval. Zoom and pan on the chart view to see as much detail as you want for any part of your workout.
Upload your workout data directly to your TrainingPeaks.com or Sportlyzer.com account.
• Heart rate
CrewNerd supports the Zephyr HxM Bluetooth heart rate monitor and all Bluetooth SMART monitors. Bluetooth SMART requires Android version 4.3 or later.
• Live tracking
Stream your location and workout data as it happens to any web browser via CrewNerd.com. This is a great tool for coaches working with multiple boats, or for spectators during a race. This can also be used as a safety feature to keep track of rowers while they're out on the water.
• Speech output
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. Very handy for stand-up paddle-boarding or other activities where the phone's display can't be viewed easily.
• 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.
Waterproof cases are available to protect your device on the water. See our web site for more information.
