Junk!

Dont waste your money. Pulse works just lime the free apps. Oxygen meter not even close reads way high. I have COPD and a calibrated device, just wanted to carry one less device. Wasnt expecting perfection but at least close, this app isnt. They invite you to leave feedback but the email address isnt even valid. That should tell you something.
