SubLater — Hear It First
Delayed subtitles for Safari
Free · In‑App Purchases
When the subtitle appears with the sound, your eyes read it first and your ears never get a turn.
SubLater shows subtitles in Safari only after you've had a chance to listen. The sound goes by, then the line arrives.
[How to use]
· Settings → Apps → Safari → Extensions: turn on SubLater and set every site you use to Allow (SubLater won't run on a site left on Ask). If Safari shows a banner saying SubLater needs more permissions, open it and choose Always Allow… (Allow for One Day stops again the next day). If asked next, all websites is fine — it allows just the sites SubLater uses, in one go; it can't reach any other site.
· Open YouTube by typing youtube.com into Safari's address bar (or use "Open YouTube in Safari" in the SubLater app). Tapping a YouTube link in another app or in search results opens the YouTube app, where SubLater can't run.
· Press play. The subtitle arrives a beat late. That's it.
· Tap a word in the subtitle for its meaning. Tap the small dot at the right edge of the video to open the controls.
[Which languages?]
SubLater is built first for Korean speakers learning English.
· Any subtitle language: subtitle delay (adjustable in Pro), Reveal mode (Pro), jump / replay / loop, auto-pause.
· English subtitles: word meanings, linking marks and the Pro sound line are written in Korean (Hangul).
· Korean subtitles: tap a Korean word for its English meaning and how it actually sounds, with romanization.
· Dictation scoring: English and Korean only.
[What it does]
· Subtitle delay — listen first, confirm with the text
· Dual subtitles — the translation appears under the original (when the site carries both)
· Jump, replay, loop — stay on one line until you hear it
· Auto-pause — stops after each line so you can say it back
· Dictation — type what you heard and get it scored on the spot
· Word meanings — tap an English word for its Korean meaning, or a Korean word for its English meaning
· Linking marks — shows where two words blend into a sound you didn't expect
[Where it works]
· iPhone: YouTube — turn on Settings → Apps → Safari → Request Desktop Website → All Websites (it does not run on YouTube's mobile layout)
· iPad · Mac: YouTube · Netflix · Viki · Coupang Play · Disney+ (Mac only)
Netflix does not play in the iPhone browser (Netflix's policy). It works in Safari on iPad and Mac.
[What we don't do]
· No account, no sign-in.
· Nothing you watch, read or type leaves your device.
· No ads.
SubLater is an independent product, not affiliated with Netflix, YouTube, Disney+, Viki or Coupang Play. Each service needs its own account.
[Free and Pro]
· Everything in Pro is open for 14 days after install. The app doesn't lock when the trial ends.
· Free after the trial: subtitle delay (2.0 s, on or off), dual subtitles, jump / replay / loop, auto-pause, word meanings, linking marks (dictation 10 lines a day, up to 50 saved lines)
· Pro: adjustable delay (0–5 s), Reveal mode, the sound line, unlimited dictation, 5,000 saved lines, phrasal-verb & idiom notes, ladder replay

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
· On the free plan you can now switch the 2.0 s subtitle delay off and back on — the "Off" and "On" buttons in the popup, or the delay - (off) and + (on) in the ⋯ menu (tap the dot on the video)
· Fine-tuning the delay in 0.5 s steps stays a Pro feature — the delay you used with Pro is kept and comes back when you subscribe again
