Latest reviews, United States App Store.

★★★★★Oct 25, 2025
Won’t work on newer my iPad ios 26

Would have been nice to know that before purchasing.

★★★★★Jan 4, 2023
Does not work on iOS 14+ or w/ AirPlay

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.

What's new in 1.0.5

- Fixes a bug where buffer sizes were not set correctly on iOS 18

Released Aug 24, 2018. Current version shipped Apr 18, 2026.

Store description

>>> Check out the demo videos at onyx3.com/LatencyMeter 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)
