A tiny extension for Google Calendar
Plan the time. Do the work. Check it off.
I use Google Calendar as a time-blocked to-do list. Calendar Checkoff adds the small, satisfying last step: marking a block done.

One gesture. That’s it.
Your calendar already has the plan.
Calendar Checkoff simply closes the loop.

Made for one job
No new system to maintain.
No backend. The extension runs in your browser.
No new account. Keep using Google Calendar.
No analytics. Your calendar is not a growth funnel.
No extra interface. Just the gesture and the checkmark.
