What you can use FocusCrew for
Anything that is hard to start. The timer does not know what you are working on, and nobody in your crew can see it either.
Studying and revision
Reading, problem sets, flashcards, exam prep. Twenty-five minutes is long enough to get somewhere and short enough to agree to when you do not want to start. A crew of coursemates focusing at the same hour turns revision into something with company in it.
Writing anything
A dissertation, a report, a newsletter, a difficult email. Writing is the classic case where starting is the whole problem and the blank page is worse than the work — a timer that ends makes the first block a small commitment rather than an open evening.
Code and deep work
Fifty or seventy-five minutes for work that takes a while to get into, and a label on the session so the weekly report tells you where the time actually went. The timer runs on the server, so closing the laptop lid does not lose it.
Admin and the pile you are avoiding
Invoices, expenses, forms, the inbox, the thing that has moved between four to-do lists. These are rarely hard and almost always postponed, which is exactly what a short block with someone else in it is good for.
Job applications and other dreaded tasks
Work that carries some emotional weight is the hardest to begin alone. A crew window gives it a time it will happen, and the session ends whether or not the task did — which is often the only way it gets started at all.
Practice and side projects
An instrument, a language, a course, the thing you do after hours. Progress on these is almost entirely a question of showing up repeatedly, which is what a streak records and what a crew makes easier to keep doing.
Chores and life admin
Tidying, cooking, sorting paperwork. Nothing about a focus session requires a desk — plenty of people use one to make a household task finite. Start it, do the thing, let it end.
