8 Fitness Apps That Are Cheaper Than Your Gym Membership

Price: $4 (flat fee)

A four-dollar flat fee is pretty hard to beat, no? This customizable Gaiam Yoga Studio app lets you choose a 15-minute intermediate relaxation session, or 5-minute beginner stretches, or 30-minute advanced balance — and literally everything in between. You can also create a custom flow, choosing any kind of poses you'd like, creating the order, and then letting the app guide you through.
