Building application interfaces on hand-held devices for Service Management, POS systems, Computerized Maintenance Management Systems (CMMS) and Sales Force Automation Systems has emerged as a major focus area for InApp.

Internet-connected mobile devices are important tools in our daily lives. The ability to access information in real-time and on the move, has enabled a much higher degree of responsiveness for enterprises. In order to fully harness the potential of mobile commerce, full integration of wireless devices with the rest of the Internet and with back-end application servers is required. Both the J2ME and .NET stacks offer this possibility.

Java-based mobile applications
Java, through its Mobile Information Device Profile (MIDP) and Personal Profile (PP) -oriented J2ME stack, offers a powerful platform for developing complex mobile commerce applications. Java programs can deploy on both the wireless device and the application server, independent of host hardware and operation systems. Client-side and server-side Java applications can integrate seamlessly under consistent API designs. Unlike applications built around browser-based technologies such as WML (Wireless Markup Language) and other HTML variants, J2ME applications are real programs that can handle interactive user interfaces, manipulate data, and allow offline user interaction. In contrast with platform-native applications, J2ME applications are portable across all mobile platforms and can deploy over the Internet. InApp has built fully-scalable enterprise applications where J2ME and J2EE work together seamlessly.

.NET Framework
InApp has been utilizing the .NET Compact Framework and C# for building mobile applications for Pocket PC devices. Backend storage used includes SQL Server CE and XML. Remote data access was achieved using XML Web services and also Socket communication. Network interfaces used includes wireless internet access from the handheld device and printing through the IR Port. Applications has been utilizing the code signing feature of .NET CF to improve the security.
