Great app! Can't believe this is free. So many tools I've probably used less than half of them. Some things I'd love to see: Dark mode. Please, my eyes! More customization, such as saving multiple custom settings, and custom tool groups. Ability to minimize the tool menu while still using a tool! More integrated layer functionality An easy way to redefine an object by it's position, staying in the same place but detaching from any connected construction

Exceptionally good and very user friendly. But the recent update has kinda broken it. I can no longer load my saved files without it crashing, and sometimes the undo button crashes the app, and sometimes it just crashes randomly. Never had it happened to me before so I'm pretty sure it was the last update. 5★ when you fix it. Edit: Fixed.

Almost great. The actual app is great, once you get past the nearly impossible zoom controls. An example. Set line lengths will default to horizontal. Four digit inputs will have that line run a long way off screen on a phone. There is no zoom slider, at least not one I could find, nor a zoom -+ button. Pinch zooming will almost always result in one or two additional points being added instead of zooming. Fixing this would make it a 5 star app but, as is, it's unusable on a phone.
