Rosetta Stone is also US owned.
I pay for a family plan and share it with a bunch of people. Several are government workers and use it in addition to traditional training, so it is actually an important subscription.
It’s one of my last US subscriptions.
The best language learning app IMO is Anki. It’s FOSS and very powerful (although the UI isn’t great).
Seriously, once you learn how to use it, it’s incredible how well it works. However it is also much less forgiving than Duolingo. You really need to use it everyday. If you skip more than 1 day, you’ll be so behind that it gets tough to catch up
Does Anki come with content? Like where do I get the flash cards from for a certain language? The website makes no mention of this
You can download shared decks. On the mobile app, there’s a little floating button with a plus sign that takes you to the shared decks, but I find it better to use the desktop app to import so that I can go ahead and fix any formatting issues I have too (i find the default font size to often be too small).
Sweet, thanks
AnkiDroid on F-Droid, Ankiweb only links to Google Play from their website: https://f-droid.org/packages/com.ichi2.anki/
I like memorion on android, it looks like a more user friendly anki with ability to import deck from it and many other language apps
