Not for professionals
I wrote a very favorable review several years ago, but I simply can’t recommend this app anymore. The issues persist, and the developers clearly do not have the resources to debug it sufficiently that it can be counted on for client work. It is unstable and will often lose the ability to export data in CSV or SHP (or frankly any other usable format). It is the only program where changes can be made on the fly to add feature classes while mapping and allow easy drawing similar to pen and paper in the field. The structure collector is also excellent. Don’t get suckered in by that - it’ll screw you eventually.
