Review on Spire Stone: Smart Stress Management and Fitness Tracker for iOS & Android by Rick Everett

Not very impressed. It was excruciating connecting it to the phone and constantly disconnecting during the personal information process. Finally I entered the data asap and the error stopped. The device often buzzes to indicate I'm looking tense, it's never been more accurate. Another time he hummed me while I slept, assuming I was very focused. Serious? Then I decided to put the device on the table and connect it to my phone. Guess what? My breathing rate was 22 breaths per minute and the activity line was gently moving up and down as if I was breathing. I came back 30 minutes later and this thing was still reporting 22 breaths per minute. In my view, this is an overrated gadget and nothing more. If it worked I don't think you would have to pay more than $30 for it. Definitely sent this unit back as untrustworthy and was ultimately a waste of time.
