The MyFix software is based on reading what the phone is doing. This required the application to work perfectly with the operating system on the handset. As a result, Romex needed applications that could work seamlessly across all mobile operating platforms, including Symbian OS, Windows Mobile, BlackBerry and, in future, Android.
Before Romex decided to partner with Penrillian it had developed one Java application that was capable of running on all the different operating systems but it was proving to be limiting and, in some cases, ineffective. Romex required a multi-platform partner who was expert in programming across all the different mobile operating systems.
