I try to hike in the Catskills 2-3 times each month. The iOS maps app is great for getting me to the proper GPS point for the trailheads. The trouble is the return trip: in the remote areas I hike, it's unlikely that I'll have data service when it comes time to head home. No data service = no navigation. Having a USA road atlas in the car is great for getting from state to state or city to city, but it does you no good on small country roads. The scale of this map, however, does let you see those smaller roads.
