Oura Ring 4 vs Oura Ring 3
Oura Ring is probably the most popular smart ring out there that has its own Android application (and iOS) and is able to sync with other Android health apps. They've recently launched their new model, the Oura Ring 4. Their approach was since launch a holistic wellness tracking, so it is an alternative for those looking to understand and optimize their health. V4 comes with upgraded features and a refined design over the previous version, but also with a price increase. Is it worth upgrading from Oura Ring 3 to it? Not necesarily since there's nothing ground breaking, but if you're new to the smart wearable rings' arena it's good choice.
