User unfriendly and intermittent.

Bought BP cuff, weight scale and oxipulse. Each device requires a different procedure to communicate with MyVitals. The weight scale requires two steps, the BP cuff requires four. The awkwardness of the the interfaces, inconsistency between device procedures, and the sometimes iffy auto-pair Bluetooth technology are significant challenges to ease of use. The apps UI is rather complicated as well. After spending a half hour with a support tech, I ironed out some of these hurdles. The tech admitted that Bluetooth technology is by its nature imperfect and prone to hiccups, but Ive had few problems with BT earphones, car interfaces, or keyboard/mice. Admittedly, the iHealth devices are more complex, but ultimately usability depends on ease of use. IHealth has a ways to go.
