## Flashcard Blocker Description
Every time you reach for Instagram, TikTok, or YouTube, LearnScreen shows you a vocabulary flashcard instead.

Turn screen time into learn time — 1,000+ new words a year, passively.

You don't fight the phone. You don't add another daily study session. You learn in the exact moments you'd otherwise be scrolling.

WHY LEARNSCREEN

The average person unlocks their phone 96 times a day. That's 96 wasted micro-moments — or 96 chances to actually learn something. Most language apps fail because they require willpower and a daily streak. Most screen-time blockers fail because they require willpower too. LearnScreen needs neither. It hijacks the impulse you already have and turns it into vocabulary.

KEY FEATURES

• Smart app blocker — Block distracting apps like TikTok, Instagram, YouTube, X, Reddit, Snapchat with one tap
• Vocabulary flashcards on every unlock — Learn words in 11 languages: English, Spanish, German, French, Italian, Portuguese, Russian, Polish, Japanese, Korean, Chinese
• Spaced repetition (SM-2, Anki-style, Leitner system) — Words come back at the optimal interval so they actually stick
• 1,080+ curated words built in — Or add your own custom word lists
• Streak tracking — Build a daily learning habit without daily lessons
• Focus mode and Dumb Phone mode — Get the discipline of a feature phone without buying one
• Digital detox built in — Less mindless scrolling, more real knowledge
• 100% offline and private — No account needed, no data leaves your device
• Designed for iPhone — Native, fast, minimalist, no ads

HOW IT WORKS

1. Pick which apps to block — TikTok, Instagram, or whatever steals your time
2. Try to open a blocked app
3. A flashcard appears: a foreign word with translation and pronunciation
4. Answer correctly and the app unlocks for a short window
5. Words you learn repeat at scientifically optimal intervals (spaced repetition)
6. Over weeks, your vocabulary compounds while your screen time falls

PERFECT FOR

• Language learners building vocabulary for English, Spanish, German, French, Italian, Portuguese, Russian, Polish, Japanese, Korean or Chinese
• Students preparing for exams (TOEFL, IELTS, SAT, GRE)
• Adults rebuilding a daily learning habit
• Anyone trying to reduce phone addiction or mindless scrolling
• People curious about dumb phones who still need a smartphone
• Digital minimalists, ADHD-friendly focus seekers, parents managing their own screen time

WHAT MAKES IT DIFFERENT

Duolingo asks you to open another app. LearnScreen meets you where you already are — the lock screen. No daily streak guilt. No tutorial maze.

Anki is the gold standard for memory but has a steep curve. LearnScreen ships the same SM-2 spaced-repetition algorithm with zero setup — preloaded words, instant card flow, automatic intervals.

Pure screen-time blockers (Opal, one sec, ScreenZen) make scrolling harder. LearnScreen makes the alternative more rewarding: every blocked unlock returns something you keep.

THE SCIENCE

Spaced repetition has been studied for 40+ years — from Ebbinghaus's forgetting curve to modern SM-2 and FSRS implementations. The algorithm shows you each word right before you'd forget it, so 5 reviews lock a word in long-term memory. LearnScreen runs SM-2 by default.

## Flashcard Blocker Reviews in United States

### ***** "So far really good"
Ive currently only gotten like teo words learnt but im also extremely early in learning! The creator had actually talked to me to help make it down grade to IOS 18 so I was able to use it, the only issue ive had so far is that when your selecting apps to block the menu will glitch and you have to reselect everything again, I had to reselect like 6 times because it kept resetting but from what I can see is that it just struggles to keep multi the folders open at once or something? But regardless of that, its been very helpful and I wouldnt say that makes it any less than a 5 star :]
