CatLines
Learn English with TV Shows
$0.99 · Designed for iPad. Not verified for macOS.
CatLines turns your favorite TV show moments into powerful English lessons.
Every day, CatLines gives you one carefully selected sentence from a classic TV show — complete with context, character, vocabulary, and key phrases. Study it deeply, then prove you've learned it through three progressive tests.
HOW IT WORKS
Daily Sentence
Each day you receive one authentic line from a classic TV show. See who said it, what was happening before and after, and break down every key word and phrase — so you don't just memorize a sentence, you understand it.
Fill in the Blank
Read the sentence with one word missing. Choose the right word from the options. Simple, focused, effective.
Dictation
Listen to the sentence and type exactly what you hear. Train your ear and sharpen your spelling at the same time.
Voice Test
Read the sentence aloud and get instant feedback. Build the confidence to actually speak, not just read.
Spaced Repetition Review
After you learn a sentence, CatLines schedules it for review at 1, 3, 7, 15, and 30 days — the proven spacing that moves knowledge from short-term memory into long-term recall. You'll never forget what you've learned.
Daily Streak
Build a habit you're proud of. Your streak counter tracks every consecutive day you complete your lesson, keeping you motivated to come back.
Check-in Calendar
See your full learning history at a glance. Every day you studied is marked — a visual record of your commitment and growth.
Library
Browse all the sentences in the collection. Revisit lines you love, or preview what's coming next.
Achievements
Unlock milestones as you learn more sentences, build longer streaks, and master your reviews. Progress feels rewarding every step of the way.
WHO IT'S FOR
CatLines is designed for intermediate to advanced English learners who want to go beyond textbook phrases and hear how English is actually spoken — with rhythm, personality, and cultural context baked in. Whether you're preparing for a conversation, an exam, or just want to sound more natural, one great sentence a day will get you there.
WHY TV SHOW LINES
Real dialogue from real shows reflects how native speakers actually talk. The vocabulary is natural, the rhythm is authentic, and the cultural references make each sentence genuinely memorable. You're not just learning English — you're absorbing the culture that shapes it.
One line a day. Drops of stone.
