What it measures
The desktop app card in the downloads section of OpenSubs's home page. The same page says the Free plan's transcribing and exporting are all free, and it names the desktop app as the tool for long files.
What it does not show
The page gives the word Free and no number, so the zero is that free price converted to hours. The page says the builds are unsigned, that the macOS and Windows installers include ffmpeg, and that on Linux the user installs a build with the whisper and ass filters.
