The app is lacking in important ways. Can't customize the alarms in any way. It's so loud & goes off 5 times, it's traumatic. It goes off & my heart jumps into my brain & I jump on it like a grenade bc there is no way to stop it you just have to suffer through the 5 chimes. It's horrible. So bad, I turned off the signal loss alarm bc it's so embarrassing at work constantly. Now I average catching only 50% of the data. Additionally, the transition between sensors isn't easy.
