So now I have to enter every flight in 2 different apps, ADPL and LBP MOBILE in order to keep a current logbook. I notice that for some reason LBP mobile does not automatically calculate the duration of each flight based on the out and in times. I notice that I have to hit the little calculator icon next to DURATION. This means that if I forget to hit that button, incorrect times go into my logbook. Am I doing something wrong? Why can't it do the math automatically?
