Wow! My review was read and I received immediate instructions on how to fix the problem! Thank you!!!! Now I can capture maps of my training sessions :)Previous review: I thought I bought the monthly subscription. I guess the ‘free trial’ is part of it. So it only recorded 3 minutes of my training session. Ugh!!! Just give one free day no limit as the trial vs 3 min…. I guess I have to wait 7 days till the trial is over and my subscription kicks in…

I think I found the problem that you're running into. If you selected the evaluation mode and then purchased a monthly or annual subscription, the app isn't currently turning off evaluation mode. You should be able to work around this by force-quitting the app and restarting it. I'll fix the problem in the next app update. I'm sorry for the inconvenience.
Love that data

I’ve used this app for several years every time that I’m on the water. It is easy use and helpful to review my row and my line on the map. I had some issues with the app turning off a a few years ago. After I contacted the developer, they got right back to me and worked with me to solve the issue. Great customer service.
Works well in a pinch

Downloaded it on the water because my stroke coach was almost dead, and it works pretty well. Strokes per minute and distance are consistent and accurate. Splits are a little weird, because it’ll tell me 5:25 on a sprint and 1:33 on a paddle sometimes so you kinda have to use your intuition on that but it still works well. Meters per stroke is very finicky though. It often times will be completely wrong. This app isn’t going to be as good as an NK speed coach, but it is still good
Could be more robust

I have used CrewNerd for 5 years and like it a lot. My only complaint is that it will switch off. I have set it to begin recording a practice then find later it quit. Practice records are nice but not critical. One regatta of 7.8 miles across Puget Sound out of Port Townsend was one I wished I had. Flat water shells are at their limits there. I wanted to see how consistant we were during a hour of hard rowing. Our 8x+ always was in the top 6.

I’d like to investigate this further to see if there’s anything unusual about your settings or setup that could be exposing a bug. I routinely use the app for long workouts without a problem. Please email support@performancephones.com to start a conversation about this. Thanks!
Fixed several minor bugs. See the in-app release notes for details.
