The Outsiders: Athlete Tracker

For people who like to spend time outside. Outside of their comfort zone.
The Outsiders comes with hand-picked metrics and a clear goal: to help you improve performance in an informed way. It is made for athletes who are highly motivated on their own, often self-coached, and driven by data and planning. Methodical, analytical, and, let’s be honest, already deep down the fitness data rabbit hole. We know this, because we are one of them.
This is not another “do more” fitness app. The Outsiders balances intensity with recovery, so progress keeps moving forward. If you train with intent, want clear feedback, and see training not as a hobby but as your main side project - this may be the tool for you.
*Created by the team behind Apple Watch App of the Year 2022 and a 2024 Apple Design Award winner*
For cyclists, runners, swimmers, and other performance-driven athletes who know what they need from their training app.
▶ TODAY – KNOW YOUR READINESS
Start each day with a Training Readiness score. It is based on the ratio of acute to chronic training load, combined with body metrics and sleep quality. That ratio helps track the balance between your recent training effort and what your body is currently adapted to handle. Readiness also accounts for short-term trends, giving you context that makes the score more relevant.
This helps you:
• Select the right effort & intensity for the day
• Build steadily toward goals
• Avoid injury and overtraining
All factors affecting your Readiness appear in interactive charts (Sleep, Training Load Ratio, Body Metrics).
Body metric history shows how training impacts recovery and adaptation. View data across 7 days, 4 weeks, or 6 months - scroll back as far as your history goes. Each view shows your avg, max and min values for that period.
View your sleep quality, duration, sleep stages and sleep consistency over 14 days. Longer time periods to come.
