100LS helps you train English listening with real podcasts, synced subtitles, sentence replay, and bilingual translation. No flashcards. No drills. Just real audio, one sentence at a time. 100 Days Language Study Learn English through real podcasts. No flashcards, no drills. Learn English the way you actually use it. 100LS is built for learners who are past the basics and ready to train their ear on real, unscripted English. Pick a podcast episode you're curious about, hit play, and let the content do the teaching. Synchronized subtitles highlight word-for-word as audio plays. Tap any line to jump back and replay it. Toggle your native language translation on or off. Slow it down to catch every word, or speed it up to push your comprehension. Repeat until it clicks. Features Synced Subtitles Every word lands on screen exactly when it's spoken. Tap any subtitle line to jump to that moment in the audio — no scrubbing, no guessing. Native Language Translation Powered by Apple's on-device translation engine. Works offline. Toggle translations on when you need context, off when you want the challenge. Automatic Transcription No subtitles for an episode? 100LS generates them automatically using on-device speech recognition, then syncs them to the cloud so they load instantly next time. Variable Playback Speed 0.75x for close listening. 1x for natural pace. 1.25x–2x for review. One tap to cycle through. Learning Analytics Track your daily listening time and streaks. Small numbers add up — 20 minutes a day compounds fast. Who it's for You've studied English. You can read it fine. But listening to native speakers still feels like catching every third word. 100LS is for that gap — the one between knowing the language and actually hearing it. Requirements iOS 17.0 or later. Translation requires iOS 18.0 — language models download once on first use. Privacy Policy: https://socratop.com/privacy User Terms: https://socratop.com/terms

EchoNative — Turn the podcasts you already listen to into a deep-listening practice room. For upper-intermediate and advanced English learners who want to truly understand the podcasts they listen to — not just follow along. Import a podcast RSS feed, Apple Podcasts link, or local audio file you have the right to listen to. EchoNative auto-generates word-perfect subtitles powered by OpenAI Whisper, so you stop guessing and start studying. WHAT'S INSIDE • AI Subtitles — Whisper-grade transcripts with word-level timestamps. Tap a word to hear it again. • Sentence Breakdown — Tap any sentence for an instant GPT-4o analysis: literal translation, idiomatic translation, syntax structure, and the rhetorical device behind it. • Instant Word Lookup — Tap any word for a clean dictionary card. No browser jumping, no copy-paste. • Shadowing & Scoring — Record yourself shadowing a sentence. Get an instant pronunciation + fluency score from on-device + AI evaluation. • Smart Vocabulary — Save words and phrases you actually encounter. SM-2 spaced repetition surfaces them again at the perfect moment. • Phrase Discovery — Run a one-tap scan on any episode to surface the idioms and collocations hiding in the transcript. Add them to your vocabulary with one more tap. • Anki Export — Take your vocab anywhere. One tap exports a clean .csv ready for Anki. WHO IT'S FOR You can already follow most native English content, but you want to: - Notice what slips past you in real-time listening - Build a vocabulary of words and phrases that actually matter to you (not someone else's textbook) - Practice shadowing without external apps or paper If you're at CEFR B2/C1 trying to push to C2, this is built for you.
