I’ve never used InqScribe nor any other subtitle tool, but alternativeto.net has a list of alternatives like Kainote or SubtitleEdit: https://alternativeto.net/software/kainote/?license=opensource There’s even a short Wikipedia article: https://en.m.wikipedia.org/wiki/Comparison_of_subtitle_editors

It can’t be included in the official F-Droid repos, as it is not Open Source.

It’s hardly better than any other proprietary software as the FUTO Temporary License does not allow users to make modifications and share them with non-programmers. They could include ads or spyware and no one would be allowed to strip that out and share the result with others.

They also clearly forbid redistribution “directed towards […] monetary compensation”. But F-Droid has to be compensated for their server costs as well, and they ask for donations as they should be. That’s why limiting commercial redistribution alone is a huge issue that would keep it from ever being called “Open Source” or “Free Software”.

I’ve used it quite extensivly, big fan. It asks for further details on objects that have already been mapped, which also reveals things that don’t exist anymore. It turns mapping into a really fun game with currently 163 different quests. The app also regularly asks you to verify opening hours or confirm the existence of certain objects. That being said, I almost always use it in conjunction with a real map editor, to add new stuff I find or to make more complex edits.

What’s missing from the existing ones?

That’s what I’ve been using for a few years now, with SimpleCalendar (soon Fossify) on my phone. Didn’t have any problems yet.
