Hi, this is Radek -- I'm the creator of Tadam. I've been using the Pomodoro technique for years, but I never quite liked any of the tools for doing my pomodoros. You could, of course, use anything, even a simple kitchen timer, but there were always these little design issues that made it annoying for me. For example, I often had this situation that the 25 minute cycle was up, but I was in the middle of doing a small task. What I needed was just a minute or two to finish that little thing, and _then_ take a break. So I would ignore the timer, and 2 minutes later, I would forget I was supposed to take a break. Ugh.
I designed Tadam to solve these problems for myself. For example, a few minutes before the time runs out, a gentle notification pops up in the corner to remind me I need to hurry up. And when the time is up, a big window pops up prompting me to take a break. If I need just a few seconds, I can move it to the side, but I won't forget about the break, because it will snap back into place after 30 seconds.
At the same time, I didn't want a tool that's super complex, with many features I don't need. Or a big "productivity system", that requires me to be a religious about Pomodoro.
All I needed was a simple tool that helps me remember to take breaks, but without being too annoying. Tadam solved it for me. And I hope it helps others, too :)
