Screen sizes....?

I'm pretty sure there is a setting "Fit Any Size", or something like that, but not sure if that will do it for you. Give it a shot.

you may use stretch to fill display mode.

I tried that and the graphics get all strange looking, but it does work.

Look at the two methods mentioned here, particularly the second one: http://community.clickteam.com/threads/74189-Scaling-for-iPhone-5-and-iPad-HOW-TO-DO-IT-RIGHT

And yes, they do apply for Android as well.

on android there is a mode to just adjust window size too, but then your app needs to be extremely flexible. fit inside and adjust window size is my favorite.

I think iOS also has adjust window size, since I remember the guide mentioning it. Fit inside and adjust window size is a pretty good option, I agree.
