lacks configuability

It has no configurable for functionality! I cannot find any. There is not even a help feature!
I have regret buying this! But there was no way of trying it out unless I bout it. :-(
I is perhaps great for those who can use the fixed resolution! I needed a flexible, configurable that will monitor my sound system in the auditorium with an adjustable scale for db amplitudes.
I can use this app!

Now how to get my money back?
