But for the most part, isn't it self-defeating (outside of graveyard hours)? If I see that my gym is low-traffic or nearly empty, I'm going to go there. Surely I can't be the only one with that mindset, so suddenly, low-traffic periods are quickly followed by spikes of use. This probably breaks down in the midnight-5am range, but overall, I think it's going to be hard to break past that mindset for an app.
