With ten customizable watch face complications, it offers a glanceable, clutter-free way to track your heart health without distractions or unnecessary metrics. Developed by the creator of HRVSpark, RHRSpark appeals to health enthusiasts, quantified selfers, and anyone seeking unfiltered, real-time heart rate data in a sleek, straightforward format. Its one-time purchase of $2.99 for the Pro unlock makes it an accessible option for those who want reliable, no-subscription health insights on their wrist.
