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.

more 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.
1.6.1 20 Mar
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.

1.5.3 17 Feb
We’re continuing with our focus on usability. This update adds more customization, helping you keep relevant data in view.
CUSTOMIZATION
Across the Today tab, Progress tab, and Training Goals. You can now reorder sections and hide what you don’t need right now. Bring the data points that matter most to you to the top. Customize button is at the bottom of each section.
One last thing worth repeating: your data stays yours. The Outsiders runs on your device, without user accounts or servers. No ad platforms, no AI models, no third parties in the middle. Your training data lives with you, where it belongs.
If being an Outsider feels right, don’t disappear into the woods alone. Mark the trail for others chasing the same goals - a 5-star rating and a positive review on the App Store helps fellow athletes find their way here, grows the community, and fuels the small team to keep building.

1.5.2 28 Jan
We’re starting 2026 by upgrading Training Goals - we can likely agree it’s one of the most essential parts of an athlete’s early-year planning. Based on your feedback, and thank you for it, here’s what’s new!
Expanded Goal Types
You can set training goals for:
• Number of sessions
• Time in Training Focus Zones
• Time in Heart Rate Zones
• Time in Cycling Power Zones
Interactive Charts
Training Goals history charts became tappable. Press and hold to inspect the details of each past goal period.
UX & UI improvements
Think your most recent workout types appearing at the top when creating a new goal, and the ability to set goals across both indoor and outdoor versions of the same activity (cycling, running, rowing, and more), etc.
Refined Post-workout Training Readiness
The calculation is now less punishing, aiming to better reflect effort and recovery instead of dropping straight to the floor.
If being an Outsider feels right, don’t disappear into the woods alone. Mark the trail for others chasing the same goals - a 5-star rating and a positive review on the App Store helps fellow athletes find their way here, grows the community, and fuels the small team to keep building.

1.5.1 13 Jan
As the year winds down, it's hard not to start thinking ahead. This update, last one of the year, helps pin the plans down. Introducing:
▶ PERSONAL TRAINING GOALS
Set clear targets for what matters to your training and track how consistently you’re meeting them, in the Progress tab.
What you can set goals for
• Time
• Distance
• Training Load
• Active Energy
• Elevation
How it works
• Choose the workout type
• Pick a timeframe (weekly, monthly, yearly)
• Set your target and train as usual
Stack as many goals as you need, mix time horizons, and adjust them as your training evolves. You’ll see your current progress, trends, and past periods, all in one place.

Sometimes the smallest details make the biggest difference. And this week, that detail sits on your wrist: The Outsiders Apple Watch Complications.
Without further ado, here’s what’s new with this one:
▶ APPLE WATCH COMPLICATIONS
Your two essential daily metrics now one glance away on your watch:
Training Readiness (TR)
Training Load Ratio (TLR)
Choose from rounded or corner styles, with TLR also offered in a rectangular layout.
▶ BUG FIXES
A handful of smaller issues you likely never saw (but we definitely did) have been cleaned up.
If The Outsiders fits into your training, a 5-star rating or brief review means more than you may think. It brings more athletes into the fold and keeps our small team moving forward.

1.3.2 03/12/2025
With the Apple Watch app landing two weeks ago, we are back to the iPhone. Here’s what is coming your way:
▶ NEW FEATURES
• Batch Photo Import to Workout Summary - your workout summary can now be paired with all the photos from the session with a single tap (Profile -> Settings -> Match Photos With Workouts).
• Indoor Cycling Speed Metric - added by user request and now available as a metric for indoor cycling workouts.
▶ UPDATED FEATURES
• Normal Range Calculation - body metrics now use an improved and more accurate normal-range calculation.
• Training Readiness Improvement - early signs of sickness are now recognised. Your readiness and status will reflect it.
• Training Load Ratio Fixes - cases with no logged workouts for a longer period are now handled properly (> 3 weeks).
▶ BUG FIXES
• Rounding is now consistent across the app.
• Workout summary charts are fixed.
• Few other minor improvements.
That’s for today. And next time, we just might switch back to the watch again - complications are in the works (hint, hint!).
Also, if The Outsiders is helping your training, a 5-star rating or review would mean a lot. It brings more athletes into the fold and keeps our small team motivated to release updates like this one.

1.3.1 26/11/2025
Hey, watch out! With this one comes a lot - a whole new app actually. Version 1.3 brings The Outsiders Apple Watch to your wrist. This marks the end of our soft launch phase and now fully into the open.
A gist of everything that’s new with this update:
▶ APPLE WATCH APP
On The Outsiders Apple Watch app Training Readiness takes center stage on Apple Watch - complete with a beautiful new animation. It reflects your recovery and recent training load, so you can quickly see how ready you are to train and what kind of effort fits today.
Alongside Readiness, The Outsiders Apple Watch app also displays:
• 7-day Training Load Ratio (TLR)
• 7-night Sleeping Heart Rate
• 7-night Heart Rate Variability (HRV)
• 7-night Wrist Temperature
• 7-night Respiratory Rate
• 7-night Blood Oxygen
• Recent nights’ Sleep Quality
All of these metrics are there by default but you have the control via the Settings button over which of them get displayed and which not (if so desired).
Kudos to Andrej and Luka for making this update happen.

1.3 12/11/2025
Hello Outsiders! Time for an update as loaded as your quads. Well, almost. For those who love to spin the pedals, we’ve got something sweet: Cycling Power Zones now just a click away. That, and lots of smaller perks. Dig in.
▶ CYCLING POWER ZONES (CPZ)
Yes, cyclist, we see you, we feel you, we are you! CPZ are now available in both the Workout Summary and the Progress tab.
In the Workout Summary, you’ll see your Power Zone distribution next to Training Focus and Heart Rate Zones for every logged ride. In the Progress tab, you can track your 4-week and 12-week Power Zone distribution under Intensity Distribution, plus your Long-Term Overview displaying weekly CPZ distribution for all your recorded history.
To see this feature, you’ll need cycling power data - which means a power meter. If you’re new to tracking power, this feature will appear after your first cycling power data log in Health.
▶ BODY METRICS
The small charts on the Today tab now have an updated visualisation and transition between ranges. If you went far outside of your normal range with any of the metrics, this should now be clearly visible even when this measurement is already in the past.
▶ WORKOUT SUMMARY
Each Heart Rate Zone and Power Zone now displays the minimum and maximum range value on the right side next to duration. This one doesn’t show up in the Progress tab, because your zones might change over time.
▶ TRAINING FOCUS ZONES
Training Focus Zones are now displayed for all the workouts with at least one minute of your heart rate measurements above the bottom threshold. You can adjust your Training Focus Zones in The Outsiders > Profile > Personal & Fitness Details > Training Focus Zones.
▶ PROGRESS TAB
Fitness cards (Endurance Fitness, Cardio Fitness, Cycling FTP) now display a date of your last logged value, to provide a better overview of your values at a glance.
▶ BUG FIXES
With this version we also introduce the following set of bug fixes:
・ HR zones not saving > should now be saving correctly.
・ Body metrics (overnight vs. all-day) confusion > resolved. If you sleep with your watch, we’ll use overnight data. Keep in mind that if you miss tracking some nights, there will be a gap in your trend. If you don’t, we’ll take daytime measurements. This (data source choice) applies retroactively to your full history.
・ Wrist temperature chart now makes sense for Fahrenheit users > it used to show Celsius limits, yikes.
If being an Outsider feels like home, don’t keep it a secret hideout - help more lost athletes find their way to the front door! A 5-star rating and a positive review on the App Store is like dropping breadcrumbs on the trail (we started with a metaphor, and, in classic Outsider fashion, we’re going all in on it): it helps others discover the app, grows our community, and supports the indie team behind it so we can keep building.

1.2 29/10/2025
2 months since the official release of the app and here's another update (lost count to the actual number).
With this one, you get the following novelties:
・Upgraded charts — TLR, body metrics, and fitness charts now come with improved UX and UI.
・New Training Focus Zones settings.
・You can now choose which day your week starts on.
・Faster loading across the app.
・A fresh new icon.
・Better handling of missing nighttime data — the app now shows how long until everything’s fully operational.
1.1.1 15/10/2025
It’s been close to 2 weeks since the launch, and we are pretty happy with the way the app has been received so far. If this was a different industry then maybe we’d be able to take off a week or two, but we are in the app world.
Our devs Matija and Luka, together with Andrej on product and design, bring you this second round of updates:
- Interactive Charts:
You’re now able to tap onto most of your in-app charts on all the timeviews and check the values for any specific day in the past - Training Load Ratio, all Body Metrics, Endurance Fitness, Cardio Fitness, Cycling FTP and the long-term overview of Training Focus and Heart Rate Zones.
- Add Workouts:
Ran out of battery? Practice contact sports where wearing a watch is not an option? We have a solution, you can now add missed or non-tracked workouts directly in the app.
- RPE Sync with Health:
This feature already existed in the app but has improved with this update. Your Perceived Exertion inputs made within 3rd party apps that are stored in Apple Health can now be synced with The Outsiders and included in your Training Readiness score.
- Training Readiness:
This already sleek animation from Luka upon the app opening now got even shinier. UI at its finest IMHO!
- Some other bug fixes:
Units selection change now works in the Progress tab as well and multiple logged workouts in a single day now all stack in Today’s Workouts section in the Today tab.
1.1 29/09/2025
First batch of bug fixes!
1.0.1 18/09/2025

▶ 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.
