Fitbit
Price: Free with in-app purchases
Operating system: iOS and Android
The Fitbit app allows you to track your daily activity, sleep, calories burned, weight, hydration levels, and food intake. Your all-day activity doesn’t just count your steps but your resting heart rate—the lower the number, the fitter you are—the number of miles you’ve walked or ran, and the calories you burned during active minutes.
“I love the fact you can challenge other friends and colleagues to weekend, or weekly challenges as well as track your own performance. It’s got me more motivated than any exercise book or personal trainer,” one iOS reviewer said.

Operating system: iOS and Android
From HIIT to running to cycling to yoga, Aaptiv’s audio-based fitness classes help guide you through every workout. Each one is tailored with a carefully curated playlist to give you a boost when you need it the most. And if you don’t have access to WiFi, you can download the classes to your phone and listen to them offline.
“Like many reviewers, I’ve been looking for something like Aaptiv forever,” a reviewer explained. “I’m not a fan of gyms, videos, or on-demand workouts. I find them distracting. Aaptiv is like having a trainer on call. So far I’ve used them for spinning and outdoor running. They push you while also being supportive. In addition, the music is great. I’m seriously smitten with this.”
