Smart Rings for Men with Display Screen, Fitness Ring with Wireless Charging, Sleep Tracker Ring with Heart Rate, Health Rings for Activity Monitoring/Steps/Calories, for iOS… by Emerhome

The Smart Ring in Rose Gold is stylish and comfortable. The display screen makes it easy to track heart rate, sleep, steps, and calories at a glance, while the wireless charging is super convenient. It syncs smoothly with my apple phone, making it a reliable fitness and wellness companion. A perfect mix of fashion and function!

Battery life is about 12 hours. Mine stopped charging day three. Everything lights up to show it’s charging but an hour, two, three later still 0 percent charged. Tried a different plug and outlet. Same thing.
Readings were less accurate than expected but sports options in the app were cool.
Overall a disappointment for charge time, and device life. Sync wasn’t consistent either so time was usually off by a few hours.

I really wanted to like this ring, but no dice. The quality of the ring itself appeared good, and it’s easy and quick to charge, but that’s about it. Since it has a display, it’s easy to see when the ring has rotated on your finger, which it does all the time, even though I had a snug fit. The display turns on at random times because your next-door finger will touch the place on the display that turns it on, and sometimes also reverses the display–I set the display so it was off all day except for one minute (see below)

The main issue that I had is the heart rate is way off if the ring is wet, like when swimming or sweating. It reads about 50% high when wet, which is not acceptable for a product that is advertised as water proof, with swimming as a sport selectable on the app–it said my pulse rate was over 180 BPM during my swimming laps, which if true, would have been a 911 situation for my age! Speaking of the app, it would regularly lose the sleep data for previous days, seemingly at random. I could retrieve the data by unbinding the ring and re-binding (see below).

So many of the features of the ring are disabled in the app, but you can find those settings in the debug menu, which is reachable by a special sequence that is typical of such apps. Until you do that, you have no idea of the battery charge level, the display settings (you can set it to only display at certain times), the pulse rate measurement interval, unbinding the ring, battery charge level, camera interface, etc, etc. The app is much more flexible with those extra settings, but it still falls way short of a more expensive product. The Qring app is apparently used by many other ring and watch brands, so it’s not exclusive to this particular ring. Because of the pulse rate issue when wet, I also suspect the readings when dry, though it seemed to be correct at lower pulse rate levels, but it may be really off when reading higher levels, say above 100 BPM. The sleep data seems reasonable, but who knows? That data requires a complex set of algorithms and sensors to generate accurately, and with such a gross error on pulse rate, I also suspect all the other measurement’s accuracy.

I ended up returning the ring after using it for several weeks (thanks to Prime), and bought a more expensive product which has a dedicated (and much more extensive, but still free) app and is accurate even when wet. This ring was a good learning experience, even though it is basically a toy because of it’s inaccuracy.

This smart ring is both beautiful and practical! I love the rose gold color, and it’s comfortable to wear all day. It accurately tracks heart rate, steps, calories, and sleep, and the display screen makes it easy to check at a glance. Wireless charging is super convenient, and it pairs seamlessly with both iOS and Android devices. A perfect gift for anyone wanting a compact fitness tracker!
