Doesnt work

Updated because they released a fix hours after I wrote this review which addressed every complaint. Yay! Now it works great, although I find the interface confusing. An onboarding process would be nice so I know what Im looking at.

Previous review:
I just downloaded this to measure decibels and I cant get a reading at all. Its not registering any sound input. Totally useless. On top of that it crashes, its not optimized for retina or an iPhone 6 size screen, and the apps design shows that it hasnt even been touched since before iOS 7 came out. This is awful. Running iOS 9.0.2 on and iPhone 6s.
