If I remember correct it is covered in the visual designer video tutorial: https://www.b4x.com/etp.html?vimeography_gallery=1&vimeography_video=254439386

Tip: use as few variants as possible.

Thanks.

I have two variants (iPhone and iPad). Is there a way to get the device screen height in the layout script (to determine iPhone or iPad) so I can make some minor button position tweaks using an IF statement?

I read that Activitysize is diagonal size in inches but I couldn't find out what that value is on an iPad/iPhone as it's always given in screen height and width.

there is a readonly boolean property on the Application called "iPadDevice".
