Nix Hydration Biosensor

The app and the pod are difficult to keep paired. It takes some playing around with so allow time before your workout since the patches are single use and you can't actively play with it because a patch has to be attached for it to work. Once you start a workout it can't be stopped and resumed. I paired with Garmin and tried to start it from my workout but didn't work. Maybe user error but directions and FAQ don't provide much detail. I also learned if you start a workout from the app and what I thought was paused it until I was ready to ride that it kept running in the background so it collected 16min of data while I was waiting on others to start. I learned to not stop the workout in the app until you stop on garmin and save because it will overwrite your planned workout in Training peaks and doesn't actually record anything but time. The app and pod integration needs work to sync with garmin and training peaks. I also found it would not "announce" when I needed to drink. It shows on the screen but that requires looking at the phone. I thought it would "announce" over my airpods like the workout does via my garmin and phone. The sweat analysis was very similar to the Levelen sweat test I had taken. This is good for post workout analysis but not good for those looking to use to ensure you are staying up on hydration, especially when cycling. Since the pods are not waterproof they are useless for triathlon unless you take time in T1 to place it, sync it, and start it. I do think it is a good product for checking your hydration strategy periodically.
