As background, I’ve had the Polar H-10 and Garmin HRM-Pro recommended. My question then becomes the app they connect to.
Beyond accuracy, my key issue is privacy – I am ok syncing the device to my phone for review and analysis, but I do NOT want it to go further. I do not want my biomedical date stored on someone else’s computer (aka – "in the cloud"). I’m happy to pay for an app.
As background, my focus is on indoor exercises (aerobics, treadmills, exercise bikes and weight training), and I’m using a Pixel 4A with Android 12. Any recommendations or pointers would be appreciated.
TIA for your help – R.
