The App provides me all necessary information of gyms in my area that I can connect with using WhatsApp or SMS messages, which helps to save time for appointment-making at least twice than if not connected through this medium! It's free so no real downside here but it would be nice if they add some other services like yoga classes/courses as well since we cannot find them under their "specialty" tab yet (it only shows massage & fitness). If you're looking into connecting your friends who are active members then definitely give GymBooking Online A Try - saves loads from both sides i know there might still have been instances where one party has had issues finding each others phone number etc., however when compared side by Side its always quicker once connection made via mobile messaging apps such texting rather than calling someone back again over traditional methods.
