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:
• Running FT Pace
• Cycling Power Curve

I absolutely love Gentler Streak, and was looking for an app to aid with more serious athletic training, so I bought the lifetime version of the app! It’s somewhat barebones at the moment, but the user interface is lovely, and this app can be truly brilliant in the coming months and years provided they start working with more stats. Even at its current iteration, it is absolutely worth a try. One other recommendation: one of my favourite things about Gentler Streak is the charm about the app—the Halloween changes, the bean and whatever he does, and all that. A little personality doesn’t hurt, even for serious athletes. Would be sweet if you put stuff like that in here too, and maybe make it accessible to only those who want to enable it, or something?
Great Start

Love this app so much simple and the graphs are really great my fav is sleep stages graph. Also it will be great if you add more info buttons to all options mostly like in sleep overviews.
Developer Response
Hi! Thanks for taking the time to share your thoughts on The Outsiders and for all the kind words 💜 Regarding the info buttons, we didn't add them all over the app because each metric has its own insight at the bottom of the page. Have you checked that out? ☺️ Best, Vid
Hello there!
Last week we introduced Advanced Metrics for runs and bike rides with power data. In the past few days we made some user experience updates:
▶ BEHIND THE METRICS
If you want to see the data behind each metric, simply tap on it and you'll get the numbers used for the calculation.
▶ TRAINING SUMMARY BECOMES EVEN MORE USEFUL
Your overview of past trainings now offers two UX additions to help you analyse your progress even more. Filter by workout types, or select a specific week to see what you did in that time.
▶ BUG FIXES
Well, you know, bug fixes.
