I've looked into faucets and other apps to earn free bitcoin while I'm sitting around at work. I found an app called free bitcoin spinner and I like it a lot.
Here's how it works:
You link your coinbase account to the app and you spin a wheel to earn satoshi. The wheel will land on an amount of bitcoin to give and you receive that amount followed by watching an ad. However, I found the ads to be annoying. I solved this by spamming the "back" key on my phone after the wheel stops and it will reward your satoshi and allow you to spin again quickly without having to watch the full ad. You can choose to use 3000 or 5000 energy each spin as the reward pool changes based on the amount of energy you use.
It's VERY self explanatory and I encourage anyone with down time to try it out!
Here is the link to the app:

Have a great day and happy earning!
