Caliber offers effective workouts, metrics, tracking, weekly lessons, video instructions and nutrition syncing. All of this is 100 percent free and there are no ads or paywalls. When you sign up, the app asks about your experience and goals to create a customized workout plan. This plan is good for all fitness levels, schedules and equipment preferences. It includes workouts for at home, the gym or travel workouts. If you’re using other fitness or nutrition tracking apps, there are over 100 that can be synced with Caliber to view all your progress on one dashboard.

Every week, there are lessons to simplify evidence-based fitness principles and debunk common myths. These lessons are light and easy to follow and include topics on supplements, training, nutrition, sleep, physiology and more. If you like a community feel, there are public groups that focus on training and exercise, recipe sharing, weight loss, injury and recovery, gym playlists and more. You can also create a new group to share your progress or talk about other topics with your friends or community.
