2-hour focus timer
The 2-hour timer runs 2 hours of focus, a 20-minute break, and a 30-minute break after every second block. This is the longest block on the site, and it is meant for the handful of tasks that need to be done in one sitting: a timed practice exam, a long writing session where stopping means losing the thread, or a morning given to a single hard problem.
120 minutes is a long time. The reason to use a timer at all for a block this long is the end, not the middle. Knowing the break is coming at a fixed point makes it easier not to take an unplanned one at minute 50. One block and its break fill 2 hours and 20 minutes, which fits neatly before lunch or after it.
This preset suits students rehearsing for exams that run about 2 hours, and anyone whose best work happens in long, quiet stretches. It is not for everyday tasks, and it is a poor idea when you are already tired or when the work is a series of small items, because a 2-hour block invites drifting. For those, 50/10 or 52/17 gives you the same afternoon with more checkpoints.
Questions
can you focus for 2 hours straight
Some people can, on work they chose and prepared for. The research does not give a fixed limit for attention, so test it on one real task before making it a habit. If you drift at 60 minutes, use 90/20 or 50/10 instead.
what is a good 2 hour study timer with breaks
This one runs 120 minutes of focus, a 20-minute break, then another 120 with a 30-minute break after it. If you want breaks inside the 2 hours, 50/10 fits 2 blocks into the same window and 25/5 fits 4.
is a 2 hour timer good for exam practice
Yes, when the real exam is about 2 hours, because you rehearse the length as well as the material. Use the same start time and the same silence you will have on the day. Stop when the timer stops, even if you are not done.
