scosche rhythm+ which app

Hi all, new here :)
decided to get off my fat butt and make a start getting fit.
being a geek, I thought I use some tools to motivate me.
I got a fitbit charge hr (for general use) & a scosche rhythm+ (to monitor hr for specifics)
both paired easily
fitbit connected, updated & synced no problem.
scosche different matter, I just wanted to use it to monitor heartbeats
after dloading and joining untold apps to find you can only use hr by paying (not paying for something I havent confirmed working)
tried so many bluetooth stuff still couldnt read scosche.
THEN found BLE Debugger seemed to work with ble so hunted apps.
FOUND BLE Heart Rate (HRV) Recorder YAAAAAAA it works :)
hmm intro to long, I'll be quiet now :)
