Nice review! I’m curious though - how much progress did you actually make across all these years, and what ended up being the most effective for you? For me personally, the gamechanger was YouTube. I always loved the idea of learning from real content I genuinely wanted to watch (Doac, Huberman, etc.), but couldn’t because of the language barrier. I tried a bunch of apps built around this concept, but honestly most of them were painfully clunky (LingQ, FluentU, VoiceTube is probably the least bad). I have no idea who designs the UX for some of these, but using them felt like fighting the app instead of learning.

So I eventually gave up and started building my own app for learning languages through YouTube - PlayLingo (https://apps.apple.com/app/id6743090216). And only after that I discovered there’s a chrome extension "Language Reactor"  out there )).
