Best Fitness Trackers 2025: Comparison of Fitbit, Whoop, Oura Ring and Apple Watch

Check out our full Oura Ring 4 reviews.
Who is it:
Known for its sleep tracking features, including a negative temperature coefficient sensor that scans on scans – Oura Ring 4 is a low-key fitness tracker that provides users with in-depth information about their sleep, exercise, recovery, mindfulness and more. Former Mashable Tech editor Kimberly Gedeon offers 4.5 pieces for Oura rings on the Mashable scale, which is a great alternative fitness tracker as long as you use an iOS compatible device. “While I like the URA Ring 4, my advice depends on the device you have. I’ve tested the Oura Ring 4 on the Samsung Galaxy S24 Ultra and iPhone 16 Pro Max, and this wild, easy-to-wear wear-resistant seems to be more compatible with the other,” she wrote. “To get meaningful, accurate tracking metrics and leave it behind for this amazing metal finish (it tests better than the ORA RING 3, which will scratch soon).
Why we chose this:
The OURA Ring 4 has a lot of style, but thankfully, it also has a lot of substantiveness. Because it uses the pulse of your fingers to track your heart rhythm, not like most other fitness wearables, rather than your wrist, you end up completely getting more direct, accurate metric tracking, whether you’re exercising or falling asleep quickly. “My URA Ring 4 is still ‘fixing me’,” Gedeon wrote. “But, based on what I know so far, it does an impressive job of doing it. For example, it can relieve my stress well – showing anxiety during working hours, and the easier readings I look at as I look at Love Island United States With my fiancé on the peacock. ”
Perhaps the most impressive feature of OURA RING 4, though, is the built-in AI consultant that can environmentally thrive your tracking data and can make suggestions to help you become a healthier individual. “The AI consultant accurately pointed out that I was facing challenges in sleep and getting used to it too late. Additionally, it said that my activity level was high, but more consistent would help.”
While we obviously like the time of the URA Ring 4, there is a caveat: it’s the best when paired with an iPhone instead of an Android device. Gedeon tested wearables with both types of smartphones and said the OURA experience is more seamless and vulnerable on iOS. Also, note that once you get the URA Ring 4, you will have to pay a $6 monthly fee to make the most of the device. “Overall, OURA Ring 4 is a healthy powerhouse with stylish design and cutting-edge AI that can take personalized health tracking to the next level,” Gedeon concluded in the comments.
OURA also claims that it can tell users when or even before symptoms develop, and says it can accurately predict menstrual cycles based on temperature changes. Although Mashable staff hasn’t tested the last two features yet, ORA is definitely the top priority for the game when it comes to health and prediction features.
