I have used it and it works quite well, for certain types of work.

The 25 is just a suggestion, a starting point. There's no reason it can't be any other number.

But in the end I lost most of the ideas of the actual Pomodoro method (e.g. if you finish your work in the first five minutes of a Pomodoro, you still have to spend the twenty minutes left on improving what you did, no switching tasks within a Pomodoro -- I don't do that), what's left is just setting a timer and staying concentrated for that long. That works well for me.

What's hard is keeping the breaks short. I often start procrastinating during them and then only start the next Pomodoro much later.

There's a phone app / browser extension called "Forest" that's nice, you can set a timer and add a tree to a forest if you manage to stay off the phone / away from bad websites for that long, and add a dead tree to your forest if you failed.
