A bit poor functionality, but free

Does work on 10.13.5, although doesn’t start from AppStore UI (Open button), launched it using Launchpad.
Measures some speeds, but functionality a bit poor. Also doesn’t show on UI which disk is selected.

seems to work, but...

apart from the two ‘read‘ and ’write’ gauges it is unclear what exactly the results show; also you can’t resize the window or even move it to be able to see the bottom lines (my screen is 1280 x 800 and the app window just doesn’t fit).

Not Starting Up on Mojave

Like this software, however, it doesn't seems to work on macOS Mojave.
