InBetween finds a halfway point between two iPhone users, and then recommends a meeting place in the vicinity of that midpoint. It lets you find meeting places based on both user’s GPS location, or from a saved default spot. You can choose to meet at bars, cafes, hotels, parks, restaurants, malls or even supermarkets. InBetween uses your contact’s GPS location, so they must oblige your request before you can meet. When you send them a meeting request, they’ll receive a push notification of your invite.
