Study sessions you can't
wriggle out of.

Locked In blocks distracting sites and apps, notices when you look away or pick up your phone, and keeps score. Strict when you need it, fair when life happens. Free, private, no account.

What it does

๐Ÿšซ

Blocks distractions

Only the sites you allow open during a session. The Mac app also hides other apps and browsers.

๐Ÿ‘€

Notices when you drift

Your webcam tracks where you're looking: on the screen, away, or down at your phone. You get a gentle nudge.

๐Ÿ“ฑ

Phone face down

Pair your phone and it counts pickups. The iPhone app actually locks the apps you choose until the timer ends.

๐Ÿ”ฅ

Streaks and goals

Set a daily focus goal, build a streak, and see your best days and weeks.

๐Ÿ‘ฏ

Study with friends

Share a room code. Cameras side by side, a live leaderboard, and a poke when someone drifts.

โ˜•

Fair, not cruel

Built-in breaks, a short wait instead of a lock-in when you really need to stop, and an emergency exit.

Get started

  1. Add the browser extension. It does the site blocking.
  2. Open the app and allow your camera. A 15-second calibration teaches it how your eyes move.
  3. Optional: the Mac app blocks other apps too, and makes Locked In start with one click.
  4. Optional: your phone. Scan the QR code in the app, or install the iPhone app to lock your phone apps during sessions.

๐Ÿ”’ Private by design

Your camera feed is analysed on your own device and never uploaded or stored. There's no account, no tracking and no analytics. Your history stays in your browser. Study rooms connect you directly to your friends. Read the privacy policy.
