Works well
After many apple and assorted wear based watches, I settled on a Hello 3+. I bought one for my wife first bits not expensive and seemed to work. But on monitoring over time, I realised it to be extremely good. Battery life is astounding! 7-10% per day. The app ties up with the Apple health app perfectly. Unlike the wearos watches, it doesn’t need constant resetting to connect to the app. More watch faces would be good, but let’s put it in perspective. It’s a free app to use on a £25 watch that has great battery life, and a big bright oled screen.
