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 ▶ WORKOUTS – COMPLETE INSIGHT All your HealthKit workouts in one place. Customize heart rate zones per activity type for clearer effort tracking. Weekly, monthly, and yearly trends with detailed charts, including: • Training load, duration, energy, distance, elevation • Heart rate zones (aerobic & anaerobic, traditional 5 HRZ) • Detailed in-workout analysis • Map • Cycling power zones Power-based advanced metrics: • Efficiency Factor • Aerobic Decoupling • Relative Intensity • Variability Index ▶ APPLE WATCH APP Key stats always a glance away: Training Readiness, 7-day TLR, Sleeping Heart Rate, HRV, Wrist Temperature, Respiratory Rate, Blood Oxygen, and recent Sleep. Watch app complications: • Training Readiness • Training Load Ratio ▶ LOCALISATION Available in 10 languages: English, German, Spanish, French, Italian, Portuguese, Chinese (Simpl. & Trad.), Japanese, Korean. ▶ PRIVACY The app only reads HealthKit data on your device and never stores it elsewhere. ▶ 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.

Insights to change my training
5d ago

JKP in WA
I've used some other Apps -- often it seems like they add metrics just because they can be calculated. This is more curated.Using it I realized a mental mistake. I'm interested in VO2max as a measure of endurance. It takes time to go up so I'd track it with workouts. But this made it clear that I should really track my load a month before -- it's really my previous work that tracks with VO2max. The focus on training load and the ratio with which it's changing -- very helpful with dog walks. I track those differently (trying not tool rush my doggie too much.) still I can compare it to other types of workouts.

Great UI, but several things could be improved.

I was previously using Gentler Streak and switched to this app as I feel that The Outsiders matches my active lifestyle more. Indeed I think it does, in terms of the data presented. I enjoy looking at my training focus (it tells me I need more training in the low aerobic zone which matches my experience), my chronic load, my aggregated heart rate zones, training load ratio etc. That said I think several things should be improved before I can give the app five stars. 1. The color scheme is too neon and too aggressive. Maybe they are aiming for the professional athlete aesthetic but to me it feels like Times Square: not exactly a place for athletics. In contrast I like the more pastel color theme of Gentle Streaks. 2. It resets itself to the Today view soon after being backgrounded and it is way too aggressive. I sometimes switch away to cross check some data and then return. BAM! I get thrown back to the Today view. 3. I hate the UI for adjusting the heart rate zones. Fundamentally it’s just placing five points on the number line. Make it horizontal, and make the five points directly movable. The plus/minus buttons are a travesty. Just implement the same scrubbing behavior as the video progress bar: move left to right for changing the point, and move up and down for changing the scale where up means finer adjustments.4. When viewing Outdoor Runs, the map sometimes fails to load. The route is displayed just fine in the Health app so I know the data isn’t missing.

Good so far, but needs…

I like the app so far. It fits a niche I was contemplating getting a more expensive fitness tracker and additional subscription for. With this, I think I can stick with my Apple Watch and get 90% of the same benefits.One recommendation: report on periods of time in specific training zones. Perhaps integrate with the Gentler app for this. But if I want to target Zone 2 training, or work on VO2 max, it would be nice to have that data integrated to show the percentage of my training efforts that have been dedicated to those zones, and then additional recommendations to increase endurance, VO2, etc. Maybe have the ability to adjust or filter in settings so you can set your own targets if you don’t like the app’s pre-programmed recommendations?

Hi! Thanks for taking the time to share your experience on The Outsiders, and thanks for all the suggestions. Some of them are already being discussed and considered for adding, and the others we will keep in mind for future updates. 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. That's it for this week. Enjoy the outside!
