Yesterday I a saw a friend on facebook list an event from RunKeeper. It is a tracking application you can have on your iPhone or Android and it tells you how far you go, how fast, it also maps where you went. The app is free however you can upgrade to get more features. With the upgrade you can allow people you know to watch your movements live over the internet. You can also have a personal trainer on your iPhone or Android telling you what to do. I love going walking, running or riding with this app. All those times I have wondered how far I went can now be recorded and shown in my activity log. What a cool app. Of course you have to be careful who you allow to see what you do and when.
