Hi there,
I don't know if I'm the only one, but I regularly use SkyDemon on three devices. My iPad mini for flying, an iPad Pro for planning (large screen) and my iPhone, as I always have it to hand.
Unfortunately, as you can only log in on two devices at the same time, I have to constantly log in again.
Has allowing three devices at the same time ever been considered? I would be willing to pay extra for this. I can't be the only one... :-)
Cheers, Dave
