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.

No LED options?

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