Did nothing – Bomb Timer Review

I just downloaded this but it did nothing. Just a picture. I'm using the iPad mini, on iOS 8. There's a really cool bomb timer online that shows how much time you have while also watching the fuse. I used it in class and the (high school) kids loved it, and, more importantly, stayed on task. I was so hoping to find one similar that I could use offline for those (many) occasions that the Internet is down.
