Studio Light Setup App for iPhone/iPad

I've developed an app for studio light setup documenting which is available at app store. Check the iPad version's screenshots.
There have already been two updates to it fixing all minor issues and adding a lot of requested functionality, so the app now is very intuitive and easy to use.
I needed something like that very often and I hope you will find it extremely useful as well. It should save you a lot of time when documenting your setups:
