A new app is letting gym goers pay per minute. POPiN caters to casual fitness routines, letting users bypass expensive day use fees meant to encourage people to purchase memberships. The founder explains, “I'm not against membership…I'm against membership if you don't use it.” The startup is for the customers who don’t plan on ever signing up for full memberships, but are still willing to pay good money for some quality gym time. So far, the app is only available in NYC. (Business Insider)
