What is the best gym management software to use?

I’m a little late to the party, but I wanted to recommend a product I’ve been working on, called Martial Arts on Rails (http://www.maonrails.com). It’s an online platform for managing gyms (any kind of gym, not just martial arts, despite the title). It provides you with member signup and waivers, billing and recurring payments, a gym website and marketing tools.

Check it out and feel free to reach out if you want to talk more about it.
