It's ok Ok for mobile. Gis is a pretty powerful system that one can't expect to run so perfectly on a mobile device and of course it won't show current location... That would be gps. Silly.
Very buggy on GNex. Other apps load Esri map services much faster. Can't get operational layers to work. Doesn't show current location. Can't see secure data with password.
Good but needs improvement App needs to support multifunctionality. Has good potential.
This is out first release version.
