I always had this passion for building and using enterprise mobile applications and I thought I would take some time to highlight about a company who specialises in Mobile Development in AX
Here comes, ERP2Mobile.com (aka AX2Mobile.com) an ISV (Independent Software Vendor) whose focus is to develop enterprise mobility applications with Dynamics AX and other ERP.
Sometime back, I had this opportunity to attend this demo on Time and Materials Management Mobile solution which allows the end user to record project expenses from the mobile device and it integrates with Project module in Dynamics AX, The best part of the solution was the UX (User Experience) and the ease in which you can navigate through the Mobile Device UI, Unlike typical mobile applications, here the buttons on the device are built keeping in mind to capture the inputs in an easy manner.
ERP2Mobile Development Platform is an environment for developing or customizing mobile business applications for Windows mobile devices that connects to web-services or ERP-systems like Dynamics AX or SAP
It uses Visual Studio for building ERP apps .
ERP2Mobile can also guide and can provide a migration path for partners using Dynamics Mobile
