Canadian-based byteIDEA developed an iPhone app called “WhereTheFlock?”.
The idea behind this is to to solve the question that’s asked daily “how far away are you?”. It uses the GPS in the iPhone and lets you and your allowed users find out where you are. Your location is displayed on a map and is updated every 1.5 kilometers and captures your speed as well. Essentially making your exact location and ETA known… so there is no more hiding.
You can bookmark favourite locations such as your home or office. The app is free for a “limited time” and you can learn more here.
