If there were zero stars, I'd give it that. For $250 so far I've only been able to retrieve data from testing my thumb after waking up. This app has lost connection while running in a national park as well as inside my local gym. No data was collected, and therefore, rendering this device useless. It sends notifications while wearing it during exercise, but it loses all data to sum up my overall activity. Nothing shows as a past activity either. It's ver disappointing, especially for the price.

I've completed almost 10 workouts using the device, and it has significantly improved my hydration consistency during and post-exercise. The interface is quite user-friendly. I value the innovation behind this device, which removes the necessity for single-use disposable sensors and the process of sending sweat samples to a laboratory. I hope they work on Wahoo integration.

i am data driven. the data points this provide are great and align with what I feel. if I stay in green zone with hydration I feel better, less fatigue or muscle pain. I wish it did send alerts to my phone so I can see on the Garmin unit. could not get it as data fields on Garmin, but alerts should work. I also wish it would start intense activity on its own. many a time I got ready, and deferred starting the activity untill on the bike only to completely forget.
