One Block : Your Key Scene

End the day-of-busy-but-nothing-done.
Most days don't fail for lack of effort. They fail because everything felt urgent and nothing got decided. One Block fixes that with a single rule: choose ONE thing that matters today, protect the time, and see how it actually went.
One block. One thing that mattered. Every day.

★ ONE KEY SCENE A DAY — JUST ONE
Pick the single most important thing to focus on today. One Block refuses to let you have two — by design. Fewer, deeper. The decision is the whole point.

★ PLAN IT BEFORE IT HAPPENS
Time-block your Key Scene on the calendar with day, week, and month views. Set it the night before, get an alarm before it starts, and let the timer carry you in.

★ A FOCUS TIMER THAT KEEPS YOU HONEST
Start your block and the timer runs. Pauses are recorded as they happen, so deep focus becomes something you build — not something you pretend.

★ SEE HOW THE DAY ACTUALLY WENT
Planned vs. actual. A Focus Score from 0 to 100. Streaks, Deep Focus Time, completion rate, your best time window, and recovery rate. Receipts you can trust — no more guessing what you moved today.
WHO IT'S FOR
– Students preparing for exams
– Side-project builders and coders
– Writers and researchers
– Anyone who's tired of confusing "busy" with "productive"

WHY ONE BLOCK
You don't need more tasks. You need to do fewer, deeper. One Block is built so you end every day knowing exactly what you accomplished.
