For serious athletes who thrive outside their comfort zone, The Outsiders delivers personalized performance insights to help anyone go further without overdoing it.

What we love: Finding the sweet spot between progress and burnout with the Training Readiness Score. It weighs your training load (how hard and how long you’ve been working out recently) alongside your sleep data, resting heart rate, and other stats to show when to push, when to pause, and when to rest.

Quick tip: You can toggle among different Training Focus modes on the app’s Progress tab. Each draws on a different endurance-training principle. Go for Polarized to make the most use of a short time to train. Pyramidal is great if you’re training for a marathon and want a sustained intensity.

Meet the creator: The Outsiders comes from the same team behind Gentler Streak, the winner of the App Store Award for Apple Watch App of the Year in 2022.
