Cool but misleading in some respects

I have been trying to find an easy-to-use GIS app to incorporate shapefiles and raster data into my daily fieldwork. I was excited to find this one, and it does have its perks. There are tons of choices for projections and the interface is pretty intuitive (with some major exceptions). There are quite a few inconveniences and drawbacks, however.

- To import raster data you have to have processed it using MapTiler, an open source software program that is only free if your images are smaller than a certain size (we are talking like 30 MB or less here) which is just not feasible for someone doing actual GIS work.
- All of the raster and shapefiles must be zipped and hosted on Dropbox (which is cool and convenient if you have enough space) - you can also use a USB.
- There is no intuitive way to add the imported layers to your project, and there does not appear to be a help file for the latest release, so this is somewhat frustrating (and as I write this I still have not figured out how to add my imported shapefiles).
- Would be nice if it displayed your location or coordinates anywhere in the free version since there are free apps that also do this.
