Sounds like a work profile, so you could probably simulate it already with something like Island. Although I can't remember if it also has a PIN feature.
The problem with Language Transfer is its very limited language selection and its format.
Duolingo allows reading, writing, listening and speech (last two can be disabled if unsuitable in your context), and it does not impose daily limits. I've yet to find an alternative app that does all 5 of those things.
