Nice and simple so very good, but once the max HR alert is reached it alerts almost every second and is then too noisy. A few initial alerts is a good start to get the attention but after that it's too much and alerting should be less frequent (or configurable). It's not easy to rapidly bring your HR back down so having a constant beep doesn't help. Good that developer is looking to improve this 👍

Thank you for your kind feedback! I'm working on a solution. I hope you'll re-consider the rating once I fix the issue.

better than the professiona apps! Why? because its SIMPLE. When I'm working out I don't want to look at the app, I just want to know if my heart is in the zone. For my morning readiness reading I use Polar Sensor Logger for 3 minutes, upload that to Gemini, and it gives me better feedback than Polar, HRV4Training, or Elite HRV. For my workouts, I run Polar Sensor Logger in the background and use this to keep me in that days zone. I was making my own app when I found this. Use this!

Great app!! If you need a realtime heart rate monitor with min/max heart rate alerts that can pick it up from. Polar and other devices, this is it.
