ErpDoors community, original version - a native IOS client for the OpenErp open source project.
Offers limited usage (menu upload, history, lists), and the same look and feel as the enterprise version - ErpDoor
"Learns" requests, greatly improving the responsiveness vs. the desktop or web clients.
Client - server traffic is minimized.

The pro version app, ErpDoor is available on iTunes.
