I think it would be a great idea to have a section in the NTU Sports app that says how busy the gym is so you can plan your exercise around when the gym is less busy. It would be even better if this could be isolated to certain rooms/floors - or even machines/areas to see whether the exercise equipment you'd like to use is free. Someonetimes when I'm on the ground floor of the city gym and its busy, it can be intimidating to go upstairs if I'm not sure if it will be busy/all the machines will be in use so it would be nice to know before I make my way up stairs too.
