This is a great concept IF the app were able to detect pulse for a solid 55 seconds. More than 70% of the time it loses connection to the thing measuring pulse before the time is up, and the whole process takes on average about 5 tries with varying levels of success. This is pretty consistent throughout different measuring tools - I’ve used their ECG receiver, finger sensor, HR monitor, and a Under Armour HR monitor. Actually, the tool that worked the most often was the UA HR monitor, but still around 3 tries every time to get it to work. I wouldn’t recommend any of the other tools they sell.

This is a great tool if your training for an event. I use the finger sensor every morning to get a snapshot of my cns. More than a few times I've adapted my workouts because of my HRV results ( if it's low I'll do light cardio or just scale the workout back, if it's really high I'll find a workout that really pushes me). It seems to be very consistent & the finger sensor makes it simple & quick to do first thing after awaking. The only reason I didn't give it 5 stars is I'd like to see the actual numbers it measured & I'd like to be able to slow down the visual breathing tool.

While many of my friends are getting sick or injured due to overtraining, this app helps me make solid, science-based decisions on how hard to go on any given day. Paired with TrainingPeaks, it paints a crystal clear picture of both systemic and localized fatigue versus readiness. Big fan.
