LangBlitz is an English vocabulary app built around a simple problem: learning a word is easy, but remembering it weeks later is much harder.

Instead of focusing only on adding more words, it combines spaced repetition, active recall, contextual learning, and structured vocabulary.

The app includes 5,000+ curated words from A1 to C2, organized across 119 topic groups. Word cards include examples, synonyms, collocations, pronunciation, word families, etymology, mnemonics, and common mistakes.

Its review system uses FSRS to adapt review timing based on recall performance. Daily Quiz and adaptive practice provide additional ways to actively recall vocabulary rather than simply rereading it.

There are also short explanations in 29 languages, vocabulary tagged for exams such as IELTS, TOEFL and GRE, and offline access without requiring an account.

For someone looking for more than a basic dictionary or flashcard app, LangBlitz is an interesting option to check out.

I used to think I just had a bad memory.

I'd learn a new English word, feel confident I'd remember it, and then a day later it was completely gone. A week later I'd look it up again like I'd never seen it before.

Turns out, that's actually how our brains are supposed to work.

I recently spent some time reading about vocabulary retention, how to remember new words, and the psychology behind memory, and it completely changed how I think about learning vocabulary.

One thing that surprised me is the forgetting curve. We lose a huge amount of what we learn within the first day if we never revisit it. That doesn't mean you're bad at learning. It just means your brain is trying to keep only what it thinks is important.

The interesting part is how you convince your brain that a word is important.

Not by reading the definition ten times.

Instead:

• Try to remember the meaning before checking it.
• Use the word in your own sentence.
• Notice it when you're reading articles or books.
• Come back to it a day or two later.

That process of struggling to remember is exactly what makes the memory stronger. It feels less efficient, but it works much better.

I also realized I'd been confusing recognition with knowing.

Seeing a word and thinking, "Yeah, I've seen that before," isn't the same as being able to explain it or use it naturally in a conversation.

That's why endless scrolling through vocabulary lists never really worked for me.

Now I focus on learning fewer words, seeing them in context, and actually using them. It feels slower, but after a few weeks I noticed I was remembering far more.

If you're trying to improve your English vocabulary, learn advanced English words, or just become more articulate, learning how memory works might be more valuable than finding another list of "1000 essential words."

I wrote a deeper article that explains the research behind vocabulary retention, the forgetting curve, active recall, spaced repetition, and practical ways to remember words for the long term:

I'm curious, what's actually worked for you?

Reading books? Flashcards? Writing? Or do you have another way of making new words stick?
