1 hour timer for a deep work block
A 1 hour timer is a full block. Use it for exam practice or deep work when you want the end visible without checking a clock.

A full hour on the spare screen
An hour is long enough that a tiny timer becomes something you forget, and then something that startles you. A large countdown stays in peripheral vision. Exam practice is the clearest use: start when the paper starts, write until zero, and stop. The overtime count tells you how far past the limit you went if you finish a last sentence. Deep work uses the same shape. Decide the block before you start, put the timer on the screen you are not typing on, and do not renegotiate at minute forty. The digits switch to hours once the length is an hour or more, so this page reads 1:00:00 at the start and keeps that layout while it counts down. You can still read it from across the room. Take a break when it ends. Stacking hours without a pause is how a plan becomes a blur. If the work is a ninety minute ultradian block, open the 90 minute timer instead. That page starts at 1:30:00. Keep the device awake. An hour is long enough for a laptop to sleep and take the chime with it, so set the system sleep timer longer than the countdown, or use an iPad with Auto-Lock set to Never.
FAQ
Does the display stay readable for the whole hour?
Yes. At an hour or more the digits include the hour, so the size does not jump when you cross from 1:00:00 into the fifties. Burn-in shift can nudge the layout a few pixels if the same screen will show the timer often. Dim it at night so the panel is not at full brightness for the whole block.
Can I run exam practice without a sound?
Yes. Set Sound to Off, or volume to zero. The digits and the tab title still change at the end. A silent room stays silent. Turn the chime back on when you want an alarm you might miss because you are looking at the paper, not the screen.
