To make it easier to use the advantages of hybrid apps with Neptune Applications we have launched the Neptune Client which is available on Google Play and App Store.
Windows Phone and Windows 8 apps are in development and should be available as well in the near future.
Just search for “neptuneclient” on Google Play and “neptune client” on App Store and you should find it:
Some brilliant developers from TechEdge such as Luca Grilli Fabio Di Micco and Andrea Ranchetti got the task to develop this.
The result is an app that will use our IDES system for demo purposes but that can easily be configured to connect to any SAP backend with Neptune installed. Just go to preferences and set up your own backend.
The solution is based on our Neptune AppCache functionality for SAPUI5 and thus the apps you run on it will automatically be updated when an application is changed in the ABAP backend.
When using the demo apps there are some that are running in offline mode so remember to synchronize the data the first time you test them out (Synchronize tile on some of the apps like sales order).
All standard Phonegap/Cordova plugins are available and in addition we added some of the most common third-party plugins such as the BarCode scanner. There is an example of this in the demo Inventory Count App - remember to sync this app as well.
Download and test it out. It should give you an idea on how SAPUI5 works with Hybrid Apps even if you are not using Neptune Application Designer for development.
We will continuously add new content to the demo apps and as stated above we (That means the TechEdge developers 
) are working on the Windows apps and also will try to include SAP Mobile Platform configuration for the next update.
UI5 rocks!
