  • Group Pomodoro where you write aim & result?
    There are Discord servers that do group pomodoros, or websites like hours.zone, but these tend to focus on general to-do lists rather than goals for each pomodoro session. Source: about 4 years ago
  • Looking for friendly & supportive morning work session buddy
    I like hours.zone because we can see what each other is working on. I break up my work into lots of tiny tasks and aim to clear the whole list before the session ends, so it's a bit like a game. Source: about 4 years ago

    I'm serious about this and would do anything to make this buddy thing work. We can check on each other at a fixed time every day and virtually study at Hours.zone. Source: over 4 years ago
  • Time lapse of some assignment prep in bed!
    - I use a website called Hours with friends so we can hold each other accountable. The time lapse trick is one too - I took this video specifically because I was struggling to focus - because I don't want my time lapses to be of me wandering off onto Reddit when I should be studying. This post was part of my accountability for myself :-). Source: over 4 years ago
