Immediate App Crash / Close

I just downloaded the app hoping to be able to learn a bit and tinker with circuits. However, the app immediately crashes back to Home Screen. Gave two stars because it’s a good idea but ultimately useless for me.

Difficult to use

Extremely difficult to move items around

No LED options?

How about add in some simple LED options? I’m going to find an app that does.
