LearnScreen: Flashcard Blocker
Block Apps & Memorize Words
Only for iPhone
Free · In‑App Purchases · Designed for iPhone
iPhone
Every blocked app teaches you a word. Master 1,825 a year — just 5 a day, no extra time required.
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.
