Most people try to aim for a maganimous amount of pomodoros like 12+ but you'll find that you cut corners to meet that demand. Rather than making it about time, focus on a few pomodoros a day and you won't decrease the quality of each session.
When you need to create a piece of work like homework or a project, pomodoro is the way to go. However, it does not seem to be as effective with communicative tasks like meetings.
You'll find that tasks that take a long time to warm up like coding doesn't really work well with 25 min pomodoros. I personally recommend a long session like an hour then 10 minute breaks. You can customize the timers through the Settings.
