I'm terribly sorry to bring up a topic that's not about Japanese in a Japanese app! I've made it my last resort, and I'm desperate for information and guidance. I'm currently practicing German and French, in addition to Japanese. Luckily, I've managed to find engaging learning resources for Japanese (thanks to you guys!) and for French too. However, my main focus, German, has been a struggle. I haven't been able to find any engaging apps or resources to practice the language. My level is C1. (As an ill person, due to the nature and degree of my illness) after constantly struggling to practice German using my depressing apps, I'm no longer able to carry on, which is frustrating. I don't want to degrade or lose the level I've reached in the language. I'm eager to continue learning and eventually make it my second native tongue. I'd really appreciate it if you could help me find engaging, free resources that are data-consumption efficient to practice the language. I wanted to rely on manga in this regard, since it's my biggest passion, but I've noticed it's really heavy in data consumption. Do you have any ideas for engaging resources that don't have these drawbacks?
C1 is already pretty high I would recommend reading books corresponding to your language level. I've found it to be the best way to uphold my knowledge level in a foreign language, when I don't have the chance to speak the language day to day.
You could also try reading news articles if a whole book seems too stressful.
