This is a paid app and it's not cheap. It's free to download but you literally cannot do anything unless you pay for the pro subscription. How infuriating! They should make that clear before downloading. Or at least make one of the stair types free so we know what it's like before paying for the rest. But for now, this is an immediate uninstall for me.

Seems sketchy. As soon as I installed it I saw android notify me that this pasted from my clipboard. Seems like they are attempting to steal data possibly. Also, everything requires a yearly subscription. There is nothing available for free or demo.
