Good and simple alarm application for Mac

[hzxu]

Hi, I'm looking for a simple alarm application on my MBP, I want it to ask me to have a rest every one hour when I'm working, does this kind of apps exist? And if it can be launched when I start the computer(so do not need to run it manually), it will be great.

Thanks!
