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 - TLR, 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.
▶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

Hello, there!
Where we are living, spring is slowly making its entrance, which can only mean one thing: cycling season has officially started! And we are right on time with this new addition. If you’re love the stats, it’s likely you’ll give it a nod to the four new metrics that will support your power-based training.
ADVANCED METRICS FOR ADVANCED FOLKS
These four work together to give the full scope of a session - not just how hard you went, but how well you executed it. That distinction is what separates training that compounds over time from training that just accumulates fatigue.
Relative Intensity tells you how demanding the session was relative to your personal limit.
Variability Index shows how consistently you paced the effort.
Efficiency Factor indicates power output relative to heart rate - a rising trend means your aerobic engine is getting stronger.
Aerobic Decoupling shows how well you held that efficiency over the full session.
Where to find them? Open a recent ride or run activity with power data and see them in your session summary.
If you like what we’re building, we’d be grateful if you dropped us a rating and/or a review on the App Store. Helps the algorithm gods show us to other data nerds, and it reminds our small team why we’re doing this.
