A lot of people run two separate tools during a work session: a Pomodoro timer to structure the time, and a website blocker to keep distractions out. It works, but it means starting two things every time you sit down to focus, and it means the timer has no idea whether the blocker is even running — they operate completely independently, with no relationship to each other.
That gap matters more than it seems. If the timer says "focus for 25 minutes" but the blocker isn't active, the structure is just a suggestion. If the blocker is active but there's no timer, sessions tend to run indefinitely or get abandoned without a clear endpoint.
Why Combining Them Matters
A timer gives a session a defined shape — a start, an end, and ideally a rhythm of work and rest. A blocker gives that shape teeth by removing the temptation to fill the "work" portion with something else. Neither one alone solves the actual problem of staying focused for a set period; together they do.
Timer and Blocking in One Session
Lock In! combines a focus timer with website and app blocking in a single session, so starting the clock and activating the block are the same action.
Set a Duration, Everything Starts Together
Pick how long you want to focus from the menu bar, and the website and app blocks activate for exactly that window. No separate app to launch for the timer part.
Pomodoro Intervals Built In
For structured work-rest cycles, Pomodoro mode runs the blocking in sync with work intervals and lifts it during breaks automatically, so you're not manually re-toggling the blocker every 25 minutes.
Stats Tie It Together
Because the timer and the blocking are one session, the daily stats reflect real, protected focus time — not just time the timer was running with distractions still one tab-switch away.
