# How do I program 4GL and Create Mobile Apps.

GUI Compiler.
I know there is 4Js, Querix and so on; tools should be from Informix not others.

Hi Hwee,

Form the feedback I received from several people, the best tools to develop mobile apps are the tools initially designed for that: they need to have a very light footprint at runtime, which is not easy to obtain with a 4gl compiler nor interpreter.

That's, I think,  the main reason why Querix does not want to go that way, that is obtaining poor efficiency and get customers at least disappointed.

Also as far as I understand, IBM does not care anymore about this type of client, so it is highly unlikely that IBM will provide in-house solutions. Is it good or bad, I am not sure.
