The minute tracking isn’t accurate anymore. I have a few apps that track my heart rate zones and they’re all aligned to nearly the second - this one is missing chunks of minutes (as many as 20 within a zone). Not sure what’s up, but I uninstalled until it’s updated. Unfortunately this now means the app…isn’t really useful for anything. The minimum it has to get right is pulling minutes in zones correctly, which should be pretty straightforward. ### 4/5 — Weird complication - but great overall *2026-02-19* No legitimate complaints. Nice, light app that gives me exactly what I want and nothing superfluous. The complication could use work, though; it’s very awkwardly shaped. Presuming the developer hasn’t updated it for WatchOS 26, so it looks funky (app works though). ## Frequently asked questions about Cardio Rings ### What is Cardio Rings?
