DuoLingo [0] seems good for many languages and is totally free. Alternatively one might try Drops [1], which also is nice, but you only have 5 minutes a day of free practice. You'd need a subscription to exercise more every day. Drops might offer some different languages compared to DuoLingo. For example I haven't been able to learn Thai on DuoLingo, but on Drops Thai lessons are available. --- [0]: https://www.duolingo.com https://www.duolingo.com [1]: https://languagedrops.com https://languagedrops.com
