Living in today’s information-based society can have its perks. Fitness trackers function as handy assistants to give you up-to-the-second information on things like your heart rate, the number of steps you’ve taken today, and how much sleep you’re getting. Having all that information at your fingertips helps you optimize workouts, track your progress, and hold yourself accountable without paying for a personal trainer to guilt you into action. Some models feature hyper-specific workout settings to track your hikes and swims.

Here are a few of the best fitness trackers currently on the market.
