Excellent rr monitor It monitors rr timing well. Recording the values.
Where's my ability to upload gone? I am now unable to upload my results to the website from the app. This stopped 2 days ago and now says I need a premium subscription. I have paid for this app. Give me the functionality back!
nice graph and export I like the app for the nice graph and export function. What i noticed is that the recording is reset when changing the screen from portrait to landscape mode.
Can't really use this app yet... ...100% of the time I go to check my recordings it has turned itself off and NO data is available. It works fine if you want to watch the data live though. Developer is convinced I'm not mentally competent enough to understand how a toggle switch works. Recordings turn themselves off after being toggled on by a competent adult. This happens accross all 4 of my Samsung devices, so it's probably some incompatibility specific to Samsung.
