Kwibal is the app that does the negotiating for you... by splitting the difference, with a difference.
An interactive app that facilitates a negotiation between two users.
Simply fill out the short form ending with the amount you are willing to buy or sell for and let kwibal find a fair price for both parties using its unique algorithm.
users can either accept or decline the amounts calculated. Declined negotiations can opt to try again, or if both users accept their negotiation there is a messaging service in which users can keep in touch to share information.
