Comments on Instant Heart Rate: HR Monitor for Android
★★★★☆B G V SR· May 22, 2026
Been a Great Help. Unfortunately, there's no way to find out how accurate the app is. E.g., has the app been used in any University or Hospital Studies?
★★★★☆Marc Alpha· Feb 28, 2026
The free tool works well. Can't say about the paid features
★★★★★Gems & Glass Galore· Oct 20, 2025
Good app for checking your heart rate. ❤️ does have ads in free version. Does the job!
★★★★★No Fear· Oct 28, 2025
It is easy to use a great way to keep tabbing on my heart rate, so my workouts are safe. I use this often. My heart health is improving. They do have ads, however, they are at the end, so it's easy to skip.
★★☆☆☆Michelle Duty· Sep 28, 2025
I loved this app, but it no longer works for me. When I open it, it instantly closes. I have tried deleting the app and re-downloading it. Seems like the app has a bug.
★★☆☆☆Gideon Avrahami· Jan 28, 2026
Pro: So far this is the only heart rate app that I found that works on my Pixel 10, where the camera is quite far from the flashlight. Con: The ads are very big & loud, and premium is excessively expensive. Also, the "insights" list view just shows dates?! Seems useless.
★☆☆☆☆RJ Ripley· Mar 10, 2026
Not even remotely accurate readings and waaay too many ads in between every single thing you try to do! UNINSTALLED ASAP!
★☆☆☆☆Vme· Aug 24, 2025
I've used this app for years. Today it wants access to camera and video, notification, physical activity, billing, Bluetooth access, nearby device access, ad service something or other I mean it's wanting access to every thing on the phone. Nada chance. You were very useful until your demands are more than the actual usefulness of the app. Bye.
