Coinciding with the release of IBM BPM 8.5, the product team has provided a new sample hybrid mobile application for iOS and Android along with a toolkit of sample mobile coach views. You can find these on the Samples Exchange under: http://bpmwiki.blueworkslive.com/display/samples/Mobile+apps
Look for "Worklight Sample with Mobile Coach Views for BPM 8.5."
Please post your feedback and questions you have on this forum (IBM Business Process Manager mobile forum).
1) Sample mobile coach toolkit
2) IBM Worklight sample project
3) Document that explains how to setup Worklight and IBM BPM 8.5 in a production style topology.
Note that if you want to just use the sample mobile coach views without Worklight, you can do that as well. See the separate zip file download for that use case.
