Keep the task on the screen.

Lock-in is a Windows focus app for students, for people at work, and for attention that keeps opening another tab. It holds one sentence, notices when you drift, and blocks the sites you chose.

Name what you're working on.

How it works

Name the task One sentence stays on the screen for the whole session.

A nudge if you drift A thin banner on every monitor. It fades if you leave it.

Blocks you chose Sites and apps stay blocked until the session ends. A break pauses them.

One app, whoever is using it

A problem set, an afternoon of work, and a mind that wanders get the same thing. You name the task. Lock-in stays on top of the desktop, in the tray, and across every monitor. Nothing here is a social feature, and nothing plays a sound.
