Over 20 EBS mobile apps are available today for E-Business Suite 12.1 and 12.2. These apps are available for iOS and Android and cover functional areas such as Approvals, Expenses, Timecards, iProcurement, Sales Orders, Inventory, and much more. These apps are documented here:
Our mobile apps have just gone through a refresh cycle (a.k.a. "Release 6.1") along with updates to all of the server-side libraries. These updates are transparent to end-users and backwards-compatible with previous mobile app releases (e.g. "Release 6.0").
The latest versions of all of these apps use APIs that are documented in our Oracle Integration Repository. These APIs are newly-published as REST services. This means that you can now use these APIs to build your own custom mobile apps for EBS.
New guidelines for building your own mobile apps for the E-Business Suite are published here:
