I use On X and HuntStand on my phone but I also purchase the Garmin huntview chips that I use in a Garmin Alpha 100. It gives me a good Birdseye view and I can swap batteries out of it in just a second where I don't have to depend on my phone battery. Both work great. I just try and conserve my phone for Bluetooth messaging with my In-Reach or for communicating where I have signal.
