45 Minute Timer
Forty-five minutes covers most fitness class formats and a full baking project, start to cooling rack — long enough for a real session, short enough to fit around the rest of a day.
Some deep-work advocates use 45-minute blocks specifically because it's close to the point where sustained focus tends to start dropping off without a break.
It's already set to 45:00 below — press Space or Start to begin. Reloading mid-countdown resumes it rather than resetting, since it tracks a fixed end time stored on your device, not a server.
What fits in 45 minutes
A rough sense of scale for a 45 minutes block of time:
- A full workout class
- Baking a batch of cookies, mixing to cooling rack
- A focused study block before a real break
- A yoga or Pilates session
- A deep clean of one bathroom
