LatencyMeter app measures the real-world Round Trip Latency (RTL) of a given iOS audio system*. It functions by playing short test tones while simultaneously recording (listening for) the tones to return back to the input. This technique requires patching a loopback cable between audio system’s input and output.

(* iOS audio system here refers to the combination of an iPhone/iPad paired with particular external audio interface)

Would have been nice to know that before purchasing.

I tried to use this app to test a latency delay I was encountering in my Airplay 2 setup (as it would be perfect for that) but found that even after trying it on my older iPhone, it was still incompatible with iOS 14+. Paid $9.99 in hopes in would help me find whatever this dreaded RTL is but to no avail.
