Rta

Have been using it to tune rooms for small concerts, as a pink noise source and analyzer. I keep it running during the show, and it really helps isolate feedback. Haven't had the battery issue that the other reviewer had, but I just make sure to exit the app when not using it. Great work!

Just saved my bacon. Have a Trane Centravac chiller making a whine noise. This showed it is an 8k whine at the compressor. Now I have some data to go back to Trane with. I csn use this im my small audio room in my house now for some frequency readings. Its worth the dough.

Use to be the best RTA app out but have been having a lot of issues with it lately. Most recent problem is that the screen won't expand now.

Not working properly with iOS 13.0 on iPhone XS.

I use this app at least 8 days a week! When the new iOS update came out the app was having problems fitting the screen. Everything still worked as expected, just smaller. I emailed the developer about the issue and had a response in 5 minutes! That is customer support if over seen it. In the response I was assured the new update is awaiting approval from Apple. Thanks Andrew for keeping us all afloat.
