“app won’t work, I am unable to change anything in settings such as 10sec to 30 sec. EKG looks compressed and if I email it, no heart rate shows up.”
I have found that I have to record an ekg on the device. Start the app. Then turn on the device. It connects and then shows downloading 1 of 1 for example. I can then go into the settings on the app and change the recording time. Once I save the change it resynchs. If I do not have a successful data transfer with Bluetooth the settings to do transfer at the next resynch. I do not have a problem emailing a recording. Does the recording you are trying to email look ok on the computer app instead of the phone app?
