Does it have to learn to idle?

I find the best logfile results are made when during the drive you choose to display the selected data points on ONE graph as opposed to separate graphs.

This ensures you get the data points you select in the logfile.

While I do sometimes mess with the display during a drive, like disabling the legend display or some such I highly suggest concentrating on driving and not the phone.

I don't watch the phone while driving so it wouldn't matter but, if I record using a combined graph can I go back and view the log as seperate graphs?

Yes, logfiles can be viewed in your choice of layout regardless of the source view.

And if you want to get
really silly you can enable GPS recording, then replay selected data points with a map, like a video! Here is one playing at 5x speed...

I believe tjbaker57 posted a way to test the map using a vacuum pump (hand) and connecting it to the input "nipple"(removed from the intake manifold) while leaving the map connected electrically to the vehicle. Turn the key to on. Apply some form a vacuum via the pump and read the output on the obd app. The reading of the pumps meter and the app should match. I found at least one MAP that failed with high vaccum readings after a few cycles of vacuum / release / vacuum.... almost like the sensor got stuck.
