I use this to track where I want to go on outdoor trips. I like being able to use the great basemaps and switch back and forth between imagery, roads, and topo maps. Ive also added a list of places I want to go, so I can connect them to make vacations that I really enjoy.
The same points show up on my iPad as on my phone, so it doesnt matter what I use - my information is just there. Im glad that this is available for people with or without a larger Esri system.
