I download all of my my maps from the Avenza store so I don't have the issue of only being able to import 3 of my own maps. I don't make my own maps. I am using this with the Free Motor Vehicle Use Maps (MVUM) from the Forest service. Right now I have 30 of them on my phone and no problems at all. It works great with these maps to be sure I am staying on legal vehicle trails. The best part is they are used offline since most of the areas these maps cover have poor or no cell coverage.
It is pretty disappointing that there is not more flexibility in the pricing structure for this app. The developers could probably ask around $20 for a commercial license of the 3 map version and open an entirely new revenue stream. I have customers that only need 1 or 2 maps and would gladly pay that much. Fortunately there are more and more alternatives that even have some advantages. The GeoEditor app, for example, will convert geotiffs to the mbtile format. GeoEditor is awesome because you can view multiple custom maps at the same time on an open street map or satellite image backdrop.
The app itself is great, but it's far too expensive. I used the free version for a few years, and occasionally used it with bicycle and motorcycle trails that don't have good trail maps available in regular gps formats. With only occasional use, I can't justify $40, especially when it expires yearly. I use the free app now, and work around its limitations by keeping the files on the device, and load/unload them from Avenza as needed, but that looses the display of which maps are closest as well as being very inconvenient. I'm willing to pay for the app, but not $40/year.
I am a busy volunteer fire fighter so this app was a valuable tool for me. I live near the intersection of 4 maps so the 3 map limit means I can no longer rely on Avenza. As a pensioner and volunteer the $52 per year (AUD) subscription cost is too much. Have now purchased and much happier with Back Country Navigator (one-off cost) and MAPC2MAPC to convert GeoPDFs to BCN format (also one off licence). A bit fiddly but a vastly superior solution with seamless transition between maps.
I used to use this app with GeoPDF maps from my state mapping agency. Now the 3 map limit makes it unusable. I would be willing to pay $10 as a one off for the app, but not $40 per year. I'll tell those to whom I had previously recommended Avenza PDF Maps that it is now to be avoided.
This app used to be good but $50+ price tag is just bluntly stupid. There are usable app on the store for free. I used to use this a lot with pre-marked forestry maps but now it's only good for 3 maps Edit: maps I am using are State forest hunting trail maps. They also have marked ares and are only available to registered forestry users.
