Athlete Tracker: The Outsiders

For people who like to spend time outside. Outside of their comfort zone.

The Outsiders comes with hand-picked metrics to help you improve performance in an informed way. Made for self-coached athletes driven by data and planning.

This is not another "do more" fitness app. The Outsiders balances intensity with recovery. If you train with intent, want clear feedback, and see training as your main side project - this may be the tool for you.

*Created by the team behind Apple Watch App of the Year 2022 & 2024 Apple Design Award winner*

For cyclists, runners, swimmers, and performance-driven athletes who know what they need.

▶ TODAY – KNOW YOUR READINESS
Start each day with a Training Readiness score based on the ratio of acute to chronic training load, combined with body metrics and sleep quality. This tracks the balance between recent training effort and what your body can handle, accounting for short-term trends.

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 - TLR, Body Metrics).

Body metric history shows how training impacts recovery and adaptation. View data across 7 days, 4 weeks, or 6 months. Each view shows avg, max, and min values.

View sleep quality, duration, stages, and consistency over 14 days. Longer periods coming.

▶PROGRESS – TRACK YOUR PERFORMANCE
See how your training load is stacking up during the training cycles.
• Balance hard training periods and recovery weeks
• Training Goals: Set short- and long-term targets and track progress over time
• Training Focus: choose the right type of guidance according to your goals - Polarized, Pyramid, Threshold
• Track your Endurance Fitness (CTL), Cardio Fitness (VO₂ max), and cycling FTP with clear trends.

Coming later:

▶ PRIVACY

▶ DISCLAIMER
The Outsiders uses your HealthKit data and works best with >90 days of training history. If you’re new to Apple Watch or workout logging, it will need time to learn your patterns. Limited data means limited insight.

Crafted with attention to detail, by real, air-breathing humans.

Hey Outsiders!
