Gaia is my go to. For me I have enough space on my IPad that I can download a whole state. With everything thing that I want on it, any thing from game units to burn units. I used garmin to Onx but this just fits me so much better. My iPad has a holder in my Jeep and it runs off Bluetooth. So if I'm in no where Nevada it still works. It also works with CarPlay. Keep using what you like but I can get a yearly subscription for about 40.00 bucks. That's for all 50 states but I just hunt the west.
