★★★★★
"Honestly didn't expect much at this price point but it's been incredible. My sleep score and HRV are now the first thing I check every morning. It's made me so much more intentional about recovery."
★★★★★
"The fat burn tracking during my runs is the feature I didn't know I needed. I can see exactly how many minutes I spent in the zone — way more useful than a generic calorie number."
★★★★★
"I had an Oura for two years and switched. The data is just as good, no monthly fee, and I actually find myself checking this app more. Wish I'd found it sooner."
