Find My Friends
This is an app I wanted to do for a while, but never got around to actually doing it. The app lets you find your friends on a map. You can request to temporarily or permanently follow a friend. Once your friend accepts, you can see where they are. A benefit of this for me is if someone is coming to pick me up or we are both at a large crowded event, we can spot each other. In my one day of using this however, the location of my friend and sometimes myself is not very accurate. In a matter of minutes, my friend jumped from one house to another to an onramp. Find My Friends is available in the App Store for the iOS 5.
One feature I would like to see in this app is an alert function. So if a friend were coming to pick me up, I could set an alarm to trigger when my friend is within a certain area.
This is a pretty cool app where you can create you own cards with a personal message and a photo. Once you enter your apple id you can pay $2.99 in the US which includes the postage and the card will be physically sent. Cards is available in the App Store for the iOS 5.
