Tl;Dr: skip the apps unless they’re part of a bigger in-person course. Prefer reputable sources like pimsleur and mango languages. If you have no rush, get graded readers and watch a lot of YouTube, podcasts, etc.

Ok, so here are my two cents on learning languages and the whole category of learning apps. They are all flawed on some major way or another. But mostly it is about pacing learning progress.

Teaching absolute beginners is easy. They know nothing, thus anything you show them will be progress. The actual difficulty when learning a language is finding appropriate material for your level of understanding, such that you understand most of it, but still find new things to learn. This is known as comprehensible input. The difficulty of most apps is that they are not capable of detecting then adapting study content accordingly to the student’s progress. So they typically go way too slow, or sometimes too fast. Leaving the student frustrated and halting learning.

Jumping with some nonzero knowledge into any app is also torture. It’s known as the valley of despair. The beginner content is too boring and dull, now that you know a bit, but the intermediate level is way too much of a gap for you yet.

My advice is to skip language learning apps. The “motivation via gamification hypothesis” is flawed and lacks nuance and understanding of behavioral science. People don’t stop studying out of a lack of tokens, gems, streaks or achievement badges. It’s because the content itself is uninteresting and bores them. Sure, the celebration and streaks work at first, but they usually lose effect by something known as reinforcement depreciation. The same stimulus shown too much or too frequently stops being gratifying. The biggest reward for learning a language is actually using it.

A method that is known to work is to find graded readers. Watch a lot of YouTube, podcasts, social media, in the target language (avoid the language learning influencers) listen to native influencers speaking about topics you care about. Books work, in-person courses work, learning apps are good to start you up form absolute zero. But most learning happens on what you do in your everyday life. Using the language is the most effective way of becoming good at the language. Everything else is just excuses for using it.
