The first year was fabulous. Worked perfectly with my phone. But after time, the device stopped connecting to the app. No matter what I do, I cannot get the two to work together anymore. It's too bad, because it was an excellent device. And when it did work I could easily email a log of my vitals to my cardiologist from my phone. Please, help me reestablish the connection between the device and the app.

Spotty software drops out while sleeping. When it works it's fine. It records SPO2 and pulse. The problem is it has to be the only running app to work correctly. Unlike my previous where it worked in the background and I could fall asleep confident that when I awoke I would have a night's worth of recorded data, many times I wake up and it has nothing. Not even a partial, and I always make sure it's running for at least a few minutes.

This does everything I need it to do with the O2 ring, After playing with the app multiple times, I found the share button. It's slow and clunky (one session at a time) but it's there under the Share button. What it is not good at doing is giving an accurate sleep pattern. The deep sleep stages are much less accurate than those on my watch. The alert arrows on the graphs are a nice touch that isolate O2 and HR events so you can see if they are isolated, in tandem, or together.
