Hello @Mazlota
I have buy Radcore 1 year ago and im very Happy with it.
you can use it to run any VCL Application from WEB, Mobile and Tablette.
it is very responsive for all devices and for all screens.
it has a lot of lot of functions and procedures already made that help you to run any application so with that code already made you save about 60% from you time
the most important thing is the support, Mr Flavio always answer you very quick using different platforms, whatsapp, telegram and email, he is very helpfull and he never say no to you
just buy and you will never regrette it i garantie it :)
wish you a very happy developpement
