Chrome blocking
Tabs return to the work.
Distracting sites are redirected only during a live session. Your study list always wins, and full browsing URLs are never stored.
Native focus for macOS
Make room for focus.
Study Block keeps the session in sight and the noise out of reach—without taking control away from you.

A quieter desktop
Firm where it helps.
Gentle where it matters.
Study Block creates useful friction between an impulse and a distraction, while leaving the final decision with you.
Nudge ladder
A pause before the pattern.
Study Block starts with a reminder, offers a short allowance, then asks a distracting app to quit cooperatively. It never force-quits.

Floating timer
Time stays in sight.
A compact, draggable timer floats above your workspace without stealing focus. Show it, hide it, or run open-ended.
Private streaks
Momentum, kept locally.
See today’s focus, your weekly total, and your current streak. Your history and settings stay as local files on your Mac.
How it works
Set the edges.
Then start.
-
01
Choose what stays open
Add study sites and the apps you need. Google, ChatGPT, and Claude always remain available.
-
02
Start a focus block
Pick 60, 90, or 120 minutes—or use an open-ended session. Optional Focus and music controls activate with it.
-
03
Come back without residue
When the session ends, Study Block releases its timers and enforcement, restores redirected tabs, and records the session locally.
Your next block
Clear the desk.
Keep the intention.
