For people who love getting outside. Outside their comfort zone.
The Outsiders includes hand-picked metrics to help you improve performance with informed training. Built for self-coached athletes driven by data and planning.
This isn’t another “do more” fitness app. The Outsiders balances intensity with recovery. If you train with intent, want clear feedback, and treat training as your main side project, this could be the tool for you.
*Created by the team behind Apple Watch App of the Year & Apple Design Award Winner*
For cyclists, runners, swimmers, and performance-focused 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. It shows how your recent effort balances with what your body can handle, including short-term trends.
This helps you:
• Choose the right effort & intensity for the day
• Build steadily towards your goals
• Avoid injury and overtraining
All factors affecting your Readiness appear in interactive charts (Sleep, Training Load Ratio - TLR, Training Form, Body Metrics).
Your body metric history shows how training affects recovery and adaptation. View data across 7 days, 4 weeks, or 6 months. Each view shows avg, max, and min values.
See sleep quality, duration, stages, and consistency over 14 days. Longer periods are coming.
▶ PROGRESS – TRACK YOUR PERFORMANCE
See how your training load stacks up across training cycles.
• Balance hard training phases and recovery weeks
• Training Goals: set short- and long-term targets and track progress over time
• Training Focus: pick the right guidance style for your goals - Polarized, Pyramid, Threshold
• Track your Endurance Fitness (CTL), Cardio Fitness (VO2 max), and cycling FTP with clear trends.

Very informative, straight to the point and honest.I’ll be trying out this app
Training Readiness got its own home: you can now look under the hood of this feature, and understand what shapes it the most. We are also adding some support for new devices.
▶ TRAINING READINESS DETAILS. See which factors play the biggest role in your daily Readiness score. A new chart lets you track your Readiness over time, both before and after training: super cool to see! It’s available in 7-day, 4-week, and 6-month views.
▶ RECOVERY HRV. If you are one of the first to show off your new Apple Watch Series 12 or Ultra 4, we now support RMSSD HRV provided by Apple.
▶ TEMPERATURE WITH BASELINE. Temperature can now be shown relative to your personal baseline rather than absolute values. We also recalibrate the baseline if you switched to Apple Watch Series 12 or Ultra 4, which use a new sensor that reads differently from older models.
We are small, independent, passionate about what we do and how we do it. If you like our work, let others know by leaving a review on the App Store.
If you have feedback, drop by Threads @theoutsiders.app or on Twitter at @theoutsidersapp.
You can also write to support@gentlerstories.com: we read and reply to every email.
Enjoy the outside!
