I actually built a Russian app for my sister to keep up her Russian: https://billfranklin.eu/russian https://billfranklin.eu/russian It was a fork of my German app which was on HN fp a couple months ago. While the app was just to scratch an itch and probably isn't as useful as the many others available (Memrise, Duolingo, etc ad finitum), working on a project that made me use German was great for learning (probably more effective than the app itself). So my ¢2 - work on something that forces you to use the language. This project was basically an immersion course (of course a very short one).
