No longer working…

Was a good app until iPad was upgraded. Does not work with iPad Pro M4 and iOS 18.

Used to Work. Cannot Recommend

Seems like newer IOS versions have rendered this app useless. For some reason it does not respond correctly and freezes all the tome. Sadly, look elsewhere for a FFT analyzer. This app used to be fantastic. Please fix this app!

No help for this app

The HELP in app doesn’t work, showing ERROR on screen. No explanation what is what and how it works. Waist of money…
