Been using HRV4Training for a couple months now. It’s basically an app that uses your phone’s camera to track your heart rate variability (HRV) – that’s a pretty good indicator of your overall health and fitness. The idea is to help you optimize your training and recovery by seeing how your body responds to things like workouts, stress, travel, etc.
Here’s what you do: you just open the app, place your finger on the camera, and it measures your HRV. There’s also a bunch of cool features like tracking your menstrual cycle and sleep quality. Took me a while to figure some of it out, but once you get the hang of it, it’s pretty useful.
Look, if you’re into fitness and health tracking, you’ll probably like this app. It’s not perfect – the camera-based tracking can be a bit finicky at times – but overall it does the job. Worth checking out if you want more insights into how your body is doing.
