CrewNerd now available for Android!

Android app on Google PlayWe’re excited to announce that CrewNerd is now available for Android devices. The Android version includes nearly all of the features that you’ve come to know and love on the iPhone. More on that in a minute… first, some details.

CrewNerd supports devices running Android version 4.1 (Jelly Bean) or newer. The application screens are optimized for phones but the app has been tested on 7″ and 10″ tablets as well.

CrewNerd is available as a free app and runs in “trial mode” at no charge, allowing users to try the application for 100 strokes or 5 minutes at a time. To remove the trial mode restrictions, an “unrestricted use” subscription can be purchased for $1.99 per month in the United States (price varies worldwide). The subscription includes a 7-day free trial period and can be cancelled at any time.

Like the iPhone and Windows Phone versions, live tracking is supported and tracking time can be purchased for the same low price as on the other phone platforms. The live tracking viewer at is free.


The row/paddle screen for Android

On Android, CrewNerd allows you to add or remove rows on the row/paddle screen and any row can be made “double-height” to highlight the data most important to you. Just tap and hold on any data row to change its configuration. Other key features available on Android include:

  • Check and bounce data
  • Heart rate monitoring (with the Zephyr HxM monitor)
  • Coach mode
  • Full support for exporting workout data by email or over USB. Export formats include: GPX, KML, TCX, and CSV.
  • Map view
  • Add boat name, practice notes, and athlete lists to your saved workouts
  • Interval detail charts – configurable data selection, with pan & zoom support
  • Custom courses
  • Live tracking
  • Full-screen mode
  • Adjustable stroke sensitivity and GPS speed smoothing

Over the coming weeks and months we expect to add support for speech output and additional heart rate monitors. Other minor differences with the iPhone version will be addressed as well.

We look forward to your feedback!

Recent iOS updates

We’ve made a couple of updates to the iOS version recently. Version 4.05 made it possible for all rowers & paddlers to get performance data from the iPhone by speech output. This was originally developed for vision-impaired athletes, but is now easily usable by anyone. The speech output can be tailored both in frequency and content so you can get the data that you want, when you want it.

In version 4.06, we’ve made a slight adjustment to the way that distance and speed is calculated by CrewNerd. In the earlier iPhone models (3G and 3GS) the GPS readings were less accurate and tended to overestimate the distance actually travelled. CrewNerd compensated for this error using an adjustment algorithm that worked very well at the time. Recent on-the-water tests with newer phones have shown that the GPS accuracy is much better now, rendering the old adjustment code obsolete.

With version 4.06, distances will now be reported as just slightly longer, and speeds will be slightly faster. Based on a series of on-the-water tests and validation using Google Earth, the new update appears to be more accurate than ever before.

SpeedCoach Mobile is now CrewNerd!

Big changes here at Performance Phones! After five years, the agreement with Nielsen-Kellerman under which we were using the SpeedCoach Mobile name is expiring, so it’s time for a change. After extensive research and several focus group sessions (just kidding), we settled on “CrewNerd”. Choosing a name is hard, but this is short enough to fit under an icon and hopefully easy to remember. We hope it will grow on you. CrewNerd 4.0 is now available for both iPhone and Windows Phone.

The other, more significant change is that we’ve added a new “Live Tracking” feature to the app. With live tracking, you can send your location and performance data to your coach in real time. It’s similar to the data transmission feature in the SpeedCoach XL3/XL4, except that it works through the internet so your viewers (coaches or spectators) can be anywhere in the world. The viewer application is also web-based, so it will work with most smartphones and tablets.

Live tracking is something that many customers have asked about over the last couple of years, so we’re happy to finally be able to bring this to you. We think this will be a great tool for coaches, and could be a helpful safety feature for the boathouse staff as well. We’re also anxious to see how this might be used to make rowing more exciting for spectators.

The Live Tracking viewer at is free. To cover the cost of operating the internet relay, rowers pay a very small per-hour fee when using the feature. The fee is paid by purchasing “tracking hours” within the CrewNerd application in blocks of 10, 25, or 50 hours. We felt that this was the best solution to keep CrewNerd and the Live Tracking viewer application completely free of advertisements.

Please give it a try and let us know what you think. We plan to continue to add features to the viewer based on your feedback. And please bear with us through the name change. We know that some links are currently broken and we’re working with our various partners and service providers to get everything repaired.

Thank you for your support!

Version 3.1 for iPhone released

The latest free update for the iPhone includes two new features and several bug fixes. A new “screen lock” feature prevents water droplets from being interpreted as touch input during your workouts. To enable this, see the main settings screen. Projected time and distance are now available through a new “Projected” data field on the row/paddle screen.

SpeedCoach Mobile for iOS Version 3.05 Released

The latest free update to SpeedCoach Mobile includes support for detailed charting of the interval data from your workouts. To chart the data for an interval, go to the history tab and select a practice. In the “Workouts” section for the practice, tap the workout of interest. At the top of the interval detail page for the workout, you’ll see a new “Charts” section with an “Interval Detail” row. Press that to see a chart of the interval data.

By default, you’ll see a chart of pace and stroke rate vs. time. Red vertical lines are used to mark off regular distance intervals and show your split for each segment of an interval. You could use this, for example, to quickly see your 500m splits in a 2000m piece.

Almost everything about the charts can be easily customized by pressing the “Configure” button in the upper right corner of the display. There, you can apply more or less smoothing to the speed, pace, and stroke rate data. You can select the data you want to see charted on the left and right Y axis (or turn off the right Y axis to reduce clutter). And the distance marker intervals can be adjusted, or turned off completely.

Back on the chart screen, you can use touch gestures to zoom and pan. Also, you can press and hold on one of the chart lines to display a cross-hair that lets you see the exact data for any point on the line. With the cross-hair displayed, slide your finger left or right to see other data values. Tap anywhere else on the screen to remove the cross-hair.

If there are multiple intervals in your workout, use the left and right arrows in the bottom corners of the screen to quickly display the data for each interval. We plan to add additional chart types in the future. As always, we welcome your feedback and suggestions!
