The app is simple to use, though the ring sizing could be more flexible. it’s a good choice for anyone wanting discreet health monitoring Review: Great bit of kit - Great purchase, I'm really pleased with it. Does everything that my fitness tracker watch did, measures steps, calories, BP, heart rate, HRV, stress, spO2 and sleep. Makes a nice change from wearing my watch which is a little bulky. I'm female and got a size 8, I'd normally be a K,L,M, and it fits my index and middle finger. I could've got a size down , 7, for a more snug fit. It measures hourly, and can track workouts too although not too many options with this. Easy to set up and came fully charged. App is nice and simple to use too. Would make a lovely gift too. Still has 100% battery after 24hrs.
