Noise Gate vs Expander on distorted guitar

Thanks for the great app and explanation!

Can you tell me how Billy Gibbons gets that tight chord sound on 'Heads in Mississippi'? Thanks.

I hate gates after I tried an expander on the PC but I can't find an expander pedal for some odd reason.

You sold me on this instantaneously. However, the app hasn't been updated since 2022. Will it be updated soon? SDKs/APIs get deprecated and I worry this will stop working on newer iOS versions.
