Didn’t expect to like this ring this much tbh. It’s super cute and doesn’t look like a fitness tracker at all, but still tracks everything steps, sleep, heart rate, even stress. I love that there’s no subscription (huge win). It’s really lightweight and comfy, I forget I’m wearing it. Plus it being waterproof makes it easy for everyday use. Definitely worth it!

Title: Surprisingly good for the price I honestly wasn’t expecting much, but this smart ring actually impressed me. It’s lightweight, comfortable to wear all day, and the battery life lasts longer than I expected. I mainly use it to track my steps, heart rate, and sleep, and so far the readings seem pretty accurate. I also like that it looks more like normal jewelry than a bulky fitness tracker. The app was easy to connect and set up too. Definitely a good option if you want a simple fitness tracker without wearing a smartwatch all day.
