This team has the most responsive and intelligent app writers for any mobile device on the market.
The layer management and export functions make this THE app for field recordation on just about any project, whether it be environmental, construction or preliminary engineering. For more accurate location based writing, use a Bluetooth GPS device. With iOS 6, there are map jumps that cause it to effectively snap-to-grid. Im sure that will be fixed very soon. (Staying with iOS 5 will prevent that issue for now.)
Compared to the cost and training required for adequate options to this app on the iPad/iPhone, this app is really a no-brainer. Really, there is productivity possible in this app that cannot be replaced by anything else in the mobile market.
