MobileBuilder is a very powerful tool if you're building data collection applications for a wide variety of platforms. Support for advanced technologies such as handwriting recognition, relational databases, and bar code scanners has made MobileBuilder the choice of a wide variety of large enterprisesincluding FedEx, United Airlines, and British Airways. Code is largely generated by the development environment, and most common tasks can be handled through the use of MobileBuilder's advanced CodeAssistant tool. MobileBuilder's use of the C programming language allows legacy code and system APIs to be accessed, unlike many mobile development tools, which use proprietary programming languages while only targeting a single platform.
If you're required to target a wide variety of platforms ranging from DOS to the PalmOS, MobileBuilder may be just the tool you're looking for.
