What's New in The Outsiders Fitness Tracker

1.8

September 14, 2026

The Outsiders are turning 1! In a way it feels like yesterday, but looking back it was a year full of meaningful updates and milestones. Thank you for being with us on this journey! This update is, as you can imagine, all about iOS 27 - it brings voice support, a glassier look, (bit of) on-device AI, and some more. ▶ SIRI APP INTENTS. Ask Siri “Training Readiness in The Outsiders” and get an answer without opening the app. Works for your readiness, workouts, sleep, or body metrics. Make sure to add The Outsiders to any prompt you make, otherwise Siri will sail its own way. ▶ ON-SCREEN AWARENESS. Go to any part of the app and ask Siri to make sense of what you see on screen, think of it as your fitness trainer on the go. For instance “summarize this workout for me”, “what does this chart mean for my training”, … find the way that works for you. ▶ WORKOUT TITLE SUGGESTIONS. On-device AI suggests a more detailed name for your recorded sessions. Like it? Save it. Not feeling it? Make your own or keep it default. ▶ DESIGNED TO FEEL LIKE HOME. Liquid Glass got glassier, improving readability across the app and making that icon really pop on your home screen. ▶ ADAPTIVE LAYOUT. Works smoothly on any screen you open it on, including upcoming iPhone Duo. We are small, independent, passionate about what we do and how we do it. If you like our ways, rate us 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!

Nice option to Garmin

I’m tired of my ultra runner friends and their Garmin watches. They’re not bad (the watches ;) but I still prefer my Apple Watch and want something sort of similar in aiding me on my fitness life. Now my bad friends who don’t use the Apple Watch…well I’ll just have to accept them.

Response from developer

Hi! Thanks for taking the time to share your thoughts on The Outsiders. While we're able to create a great app, we can't change your friends and their taste in watches, so you'll just have to accept them, yes 😜 Thanks again 💜 Vid

Nice app and modern interface

Really like the design waiting for features like body battery , bio age , stress

Response from developer

Hi! Noted. We are now working with twice the speed😉. Thanks for your help. Vid

This could be a great app!

This is one of the most visually appealing fitness apps I’ve used!

The interface is clean, modern, colorful, and does an excellent job presenting workout data. I also appreciate how much information is available—from training load and endurance fitness to heart rate zones and workout trends.

My biggest criticism is that the app often assumes users already understand advanced exercise physiology.

For example, labels like “Low Aerobic Shortage,” “High Aerobic,” and “Anaerobic” are presented without enough explanation of how the app defines those terms. During one of my indoor walking workouts, the app classified 67% of the session as anaerobic, which seemed surprising for a steady 50-minute walk. Whether the app is correct or not isn’t really the issue—the issue is that it never explains why it reached that conclusion.

I would love to see each metric include a brief explanation answering three simple questions:

• What does this metric measure?
• Why did I receive this result?
• What can I do to improve it?

Even something as simple as a tappable “Learn More” button beneath each chart would dramatically improve the experience. The app already excels at collecting and displaying data; now it needs to excel at helping users understand what that data means.

Overall, this is one of the most promising fitness apps I’ve tried. With clearer explanations and more educational context, I think it could become one of the best fitness platforms available.

Response from developer

Hi! Thanks for trying The Outsiders and for your feedback. We do have those "Learn more" buttons :) Some metrics have the "i" button on the right side of the screen, and others have short articles at the bottom of the page explaining what that metric means, why it matters and what the results tell you about your fitness. Is that what you had in mind? Also, could you drop by support@theoutsiders.app so we can check that 50-minute indoor walk? It sounds like some settings might be off on your end and I'll be happy to look into that and help you set it up correctly. Thanks, Vid

Not just for athletes

I absolutely adore this app as someone who is building fitness as I recover from chronic illness. I finally have the answer to “am I doing enough?” and “am I pushing too hard?” The best part of this app is looking back on months of history I already had with my Apple Watch, and seeing it through a recovery lens.

Response from developer

Hi! Thanks for the kind words and beautiful review💜 We're glad The Outsiders has been able to help you recover from your chronic illness and rebuild your fitness! Wishing you a speedy recovery and a smooth fitness journey! Vid

More features and google health integration

Missing lot of features like strain, recovery, sleep score and stress details important one Google health and fit but air integration. Also need weight body metric standards.

Response from developer

Hi! With the recent addition of Google Health synchronisation to Apple Health, your Fitbit should be able to record data in Apple Health, from which The Outsiders can read the data and use it to display your workouts, sleep and body metrics. Some of the other features you mentioned are already planned to be added or upgraded in upcoming updates but we’d rather focus on doing a few things at a high level than trying to cover too many segments and delivering them halfway. But we do appreciate the suggestions and will keep them in mind for the future. Thanks for giving The Outsiders a go! Vid
