Used to help with procrastinating. Press the plus button when you do one thing. Maybe read one page or answer one math question. That will add 10 seconds. You can then watch 10 seconds of a video (or do whatever you want). Use the minus button to remove the seconds if you clicked the plus by accident. You click the blank black circle in the middle to use up your seconds. The thing is, that breaks your streak. If you don't use up the time and do another thing, you will get 10 seconds plus whatever your streak is. This is to incentivize you to keep working to get a bigger reward. (If you don't like this feature, click the green dot next to the streak variable to turn it off. Click that again to turn it back on.) With a streak, 50 clicks gets you 1725 seconds (28.75 minutes) Without, you just get 500 seconds (8.3 minutes) So get all yer work done! Or something.
A thing I made for myself a while ago, but I thought eh, why not shove it on the interwebs.
