  • Great Alternative to Apple Watch

    I absolutely love this ring. I quit wearing my Apple Watch because of the bulkiness and was looking for a good alternative. After wearing the ring for a while, I wish I would have sized down. There’s definitely som discrepancies between the sizing kit and the ring itself. I use the Oura ring with Natural Cycles and I love how everything transfers over easily.

    I am a big fan of the Oura Ring and the version 4 improves upon an already great product. I do feel the data is more reliable in this latest version and the ring look much better. The finish seems to have some durability issues.
