Running Apps for Android

So I'm wondering if an app like this exists. I've been running all winter on my treadmill and working towards my first 5k in a few weeks. The difficulty I have is in keeping pace now that I'm running outside.

I'm looking for an app that I can set a pace range and it will warn me if I'm outside that pace? I know there's apps that will periodically tell me what my pace is, but would like one that will know what my thresholds are and warn me to speed up or slow down as necessary. Anyone heard of anything like this?
