I believe most of us prefer a small tablet for nav, rather than a phone. I don't know about iPhones, but the Apple iPad has no GPS capability off-grid and is therefore not a viable candidate. After pretty thorough research I selected the Samsung Galaxy Tab A 8". I suspect that a poll of users on this forum would indicate that the Samsung tablets far outnumber the iPads in use (although I have no data to prove that). An easy way to determine whether your device will actually track you while out of cell service is to put it into Airplane mode (which kills all wifi, Bluetooth, cell connectivity). If you have autonomous GPS service it will still track. I also use an app called GPS Test which actively monitors GPS satellite connectivity, to further validate proper GPS reception.
I prefer Gaia GPS mapping software, as it has a thorough library of map styles including (but not limited to) the following:
...and countless others.
- USGS Topo
- USGS National Map
- OpenStreetMap
- NatGeo Trails Illustrated
- Mapquest Satellite
- Shaded Relief Topo
- USFS Forest Roads
- USFS Topo Map
- Wildfire burn area maps
- Wilderness Area maps
Any or all of these can be layered with adjustable transparency to provide an almost infinite variety of map data at a glance. It will also allow you to import other maps. In fact, I routinely import GoogleEarth map segments for the areas that I intend to travel. And, of course, it will track your travel (and save it if you prefer), keeping a record of all pertinent statistical info including distance, average speed, max speed, elevation change, etc.
I have Avenza, AllTrails and Ride Command loaded as well, but none of them offer as much as Gaia in my opinion.
