It would be pretty cool if you could see the people at your gym on the app and possibly even have a chat feature. The gym is such a happy place for many, including myself, and it would be pretty great to see basic info, name and pic, of members within your gym community. I feel it may promote and help support members well being to, not only see each other in your gym but, have easy access in contacting them outside of workout hours. Everyone is 'busy' at working out and to interrupt their flow during that time to chat isn't conducive to beginning friendships.
Hope you'll consider because I love my gym's people, both staff and patrons! Here's to friendships within your community!
