Ring Is Great App needs work

Since the last update the app crashes and says the ring is disconnected also noticing the battery life is shorter.

Service exception

There is nothing more frustrating than getting a brand new product. Downloading the app, trying to set up an account, and then getting a service exception that won't let me proceed. So, this brand new ring I was eager to try is essentially useless — I can’t use it or get data from it. I have no idea what data it even collects. Very disappointing.

So many features do not work

The real time O2 saturation has been “coming” for some time now. The BP is not a direct measurement but model-based and needs to be constantly validated with a cuff measurement. Seems more of a marketing ploy than actual feature. The battery lasts for maybe 3-4 days at most. Very disappointed.

Crashing

You guys need to do an update I’ve had my ring for eight months with no problems and you keep doing updates and it gets worse every time the red light on my ring doesn’t even light up anymore so it doesn’t give me my heart rate or SPO2 it’s still tracking data, but the app keeps crashing so you might want to do an update. I don’t know if my ring is broken, but how am I supposed to get in touch to troubleshoot?

Fraud

Has anyone tried taking the ring off your finger and taking BP measurements or heart rate measurements? Try it! (just keep the ring within a couple of inches from your phone) It gives you the same measurements whether you're wearing it or not! This ring is bs! I had the ring 2 and now the MAX. I was supposed to get a 50% refund upon trade in. Months later I'm still waiting. I really want to like and believe it. I don't and I can't. I'm not sure about all these positive reviews about the ring or customer service. I've emailed and written reviews and no response. Experiment yourselves.
*****I'm reply to the CIRCUL reply****I've tried everything. Including sleep apnea monitoring with what appears a full battery. Nothing works!!! I've even contacted customer service and gotten no reply!!!!*****
