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.

App works fairly well, no obvious bugs. The device is comfortable, operation is seamless. The PDF image is great, and it's also zoom-able... but the sharing output is much too limited -- no color, and the bottom of the page is not printed at all. This should be fixed. UPDATE: after two years, the display quit. Device still works, sort of. But integration with the app has deteriorated. Often, I lose an entire night's records, never to be found again. The move to cloud killed it.

Seems ok 3/2026. AS OF 7/14/2023 PATCH NO LONGER WORKING! Update: as of mid-January 2023 is working, uploading O² RING to Samsung Galaxy Note8 & Google Drive as .csv OK. Update: as of 1/9/2023 @ 0515 PST COMPLETELY FAILED TO LAUNCH. BACK TO MINUS 1 STAR IF POSSIBLE. Update: as of 1/6/2023 the Android App seems to have stabilized. I was able to reestablish my account and upload data. Apparently there was a poor execution of their upgrade and took several patches to get it right.
