First of all, the App offers good prerequisite to collect field data with offline maps and many GIS related features.
But it is extremely unstable! Im not able to work more than five minutes without a collapse of the App. It happens in any occasion, and is highly annoying because often data gets lost!
The App-Support is no help, here is a 4-week-old reaction of the Developer Team: “Unfortunately, it will take some time to correct these issues.” So there is no prospect of an end, and it sounds like a bad joke for a 100€ App! Honestly this is the most labile App ive ever loaded in the App-Store.
Keep your hands off!
