The Oura Ring 3 Heritage has been available for some time, but continues to impress with its sophisticated design, good app and interesting insights into your own fitness. The focus is on sleep, heart and movement data. It is cheaper than version 4, but the full range of functions is only available with a plan (€5.99/month). The Ring 3 therefore remains an expensive fitness accessory.

It's no secret that the Apple Watch can of course do more than any of the smart rings tested here. In this respect, if you really want to use all the functions of the Apple Watch, you should of course choose it. However, if you are only interested in the health functions, a smart ring is a more than good alternative...

The Oura Heritage measures numerous health values, offers a very high pulse measurement accuracy and records a lot of activity data. The ring is also very well made and comfortable to wear.
