The "10 minutes a day to learn a language" apps are a huge waste of time

Apps like Duolingo claim that you can learn a new language if you spend 10 minutes of your time on their app every day.<br><br>That's utter nonsense. You won't learn anything in those few minutes and if you think you'll stick to doing that for years you're delusional.<br><br>It took me 9 months of consistently spending 2 hours a day to go from B1 to C.
