Nice idea @dcr

Hello people, Today is a great day for us because we're launching the beta program for our new app - Swish Fitness. Swish Fitness will connect you easily with other users and personal trainers in your area that, that like yourself, are interested in Running, Cycling, Bodybuilding or other sport activities. The process of finding a sport buddy is now so easy, you'll never ever have the excuse of not going for a run, ride or work out because you are alone. Currently, we're starting with 3 types of activity - Running, Cycling & Bodybuilding. With time, we'll work our way up to more requested activities. Main interesting feature of the app will be the experience based algorithm which will only match you with people on the same activity level as you. This way you always stay motivated and you don't have the surprise of going out with people that pull you back. Once you quickly find a user you want to interact with, you can challenge him/her, discuss a meeting location and enjoy a new way for practicing sports.  Feedback and suggestions are greatly appreciated!
