Much easier than the Cartegraph app or iPad app, has less problems and crashes. Generally pretty fast. I wish the section headers would appear when in detail view, but I really like the select the field, type, and save format over the click the edit button, select the field, type, and save layout.
App is still in it's infancy, but at v1.2.x it is already surpassing the iPad app in field reliability. Reliability gets 5 stars, but functionality only gets 3, so I'll give it a 4 for now and update in the future.
