Do you need a software development platform to power your ideas?
Do you want to build once for multiple platforms? (Windows, OS X, Linux, Android, iOS, HTML?)
Or are you looking for the perfect platform to learn to program your own mobile & desktop apps?
For desktop software development Livecode is among the best 3 platforms in the world in terms of speed of productivity as well as overall performance.
For mobile, it fell behind a little bit, but I hope it will catch up soon.
