The best "app" I discovered is on my iphone, theres a count down timer. It works great. I do not know if android has a built in app, it's been years since I used one...
That's it, the biggest thing is having something by you/on you that works. I didn't know how to use the Clock app fully outside of different timezones/alarms. I was surprised there was countdown. You can extend continuously, so you can set 15 mins or 30 mins countdown and have it continue all day if you so desire.
It's pretty powerful, I wonder how many basic built in features of operating systems I completely miss - because, the clock app seems innocent enough, it's application is really unlimited.
