Right, I changed it a lot and ended up with this mess. But it was much worse before.
I have another inverted "is in touch" to set the default values for every object (max speed, accel). I think I will rework it with the next update but its strange that it very often is sooooo slow on Safari (in browser and on "home screen" as app). After reloading it 10 times sometimes it works fast as expected (same as on pc). But I could not find a reason why it is so slow most of the time on iOS. I hope it runs smooth on Edge since its a Win10 app. I have the web export just for me cause my WinPhone is broken.
