romanticize your grind.
the aesthetic focus timer the timeline is obsessed with. press start, phone face-down, and lock in. then flex your streak and challenge a friend — that's the whole game.
“your future self is already proud of you.”
tip: hit space to start / pause
why the timeline is locking in
every feature exists for one reason: make it stupidly easy to start, and nice enough to stay.
live rain, zero ads
brown-noise rain generated right in your browser. no lofi-girl copyright strikes, no 30-second ads, no nonsense.
streaks worth flexing
day streaks, focus minutes, all-time totals — saved on your device only. screenshot-bait by design.
4 aesthetic vibes
midnight, lofi, cyber and pastel. match your mood, your wallpaper, or your entire personality.
friendly warfare
one tap sends a "bet you can't out-focus me" challenge to the group chat. losing hurts. winning feels elite.
what's lock·in?
lock·in is a free aesthetic pomodoro timer and study timer for students, creators and anyone chasing main-character productivity. it works like a classic 25-minute focus timer with short and long breaks, plus live rain sounds, daily streaks and four vibe themes. no sign-up, no download, no ads — just open the tab and lock in.
