For The Fitness Freak: ClassPass
By now, ClassPass is a classic. Not only does it easily allow you to coordinate workouts with friends, it also provides access to some of the trendiest boutique fitness studios in the city at a seriously discounted rate. To really ensure you'll never get bored, the app has recently added all sorts of cool stuff - from ClassPass Go, a free standalone app offering audio classes from top trainers, to fit and fab ClassPass Getaways - which, yes, are exactly what they sound like. Little known feature? You can also book spa treatments and massages on ClassPass!
