Hi nice folks,
I've been using this app (Bluetooth Heart Rate Monitor) successfully with an external HRM: the Polar OH1+: works great without any tweaking. This device is popular amongst runners as it goes on the arm (or legs) with a band and is super close to the precision of a chest strap (without the annoyance). Still, after the effort, I take the band out and I switch back to the usual wrist HRM by deleting the app, but then I need to reinstall it for the next run. And I run 4 times a week. Anyone would know how to add an on/off option in the code of the app ?
If there's a large set of people interested in using this watch for running, then maybe this option should be moved directly to "settings" with a HRM option showing "on/off/external".
