Why BrewMath doesn't have a timer.

Just took a look at the comments on the US AppStore (I'm British so I use the UK store by default). It seems a few people have asked for BrewMath to have a hop timer. There's a very good reason why it doesn't (well I think it's a good reason). Apple doesn't allow third party applications, such as BrewMath to run in the background. When answer a call, your program gets booted out. Can you guess what this means if you have a hop timer running and you get a call? Yep, no timer.

BeerAlchemy Touch won't have one either.
