This site is AMAZING!  I don't normally fork out money for a premium subscription, but this time I did.  This web site really helps me out when I need to keep kids from going crazy trying to find things or taking too much time on a certain task.  I also use it to time lessons.  For example: "Let's work on coding for 20 minutes and then we can have a choice".  The kids love it.   There are regular countdown timers, but also many really fun timers.  My kids like the "Minecraft Block Characters" race.  You can add your students names to the characters and introduce more fun!  The premium membership is $12 a year for one person or $50 for 30 people!  Well worth it!
