I only use the RTA as a reference
I couldn’t comment as to the calibration for SPL on my iPhone 14+ on iOS 26, but it still runs. I’d welcome an update, but doubt it will come.

Great app what happened
I used this app for years it’s great, I recently upgraded my phone and the app, now when I use the tone generator the box to enter the desired frequency is gone!! What happened that’s so greatly needed
Update needed
Great tool but calibration needs to be updated for newer iPads like iPad Air 4.
Dark mode bugs
Great app, useful tools but can’t use the wave tables or see text in parts of the app since updated to using dark mode on iOS.
