What's New in The Outsiders Fitness Tracker

1.7.6

July 28, 2026

More data, deeper analysis, and finally a Share button. This update adds new tools to help you spot where you have improved and where there is still room to push the pace or add some watts. ▶ BREAKDOWN. The old Splits section has been renamed and expanded. Breakdown now includes three types of data: • Splits are added automatically per distance. • Intervals appear if you follow a structured workout. In the Apple Watch Workouts app you can create a custom workout with warmup, work, recovery, and cooldown periods. • Segments are marked manually using a double-tap on Apple Watch or the Action button on Apple Watch Ultra. Next time you want to break a segment on your run or ride, mark the start and end, then analyse it in The Outsiders. ▶ SHARE. It took a while, but here it is. You can now share your oh-so-precious workout summary. ▶ RELATIVE INTENSITY FOR RUNNING. Now available for running workouts, based on your lactate threshold heart rate. ▶ SMOOTHER WORKOUTS TAB. The glitching on the Workouts tab is gone. Thank you for putting up with it. No more, now it's as smooth as silk. ▶ TEMPERATURE FOR NON-APPLE WATCH USERS. If you use a non-Apple Watch device for tracking temperature, this metric should now also appear in The Outsiders, as long as your tracker saves data to Apple Health. ▶ REFRESHED UI/UX FOR ADDING A PERSONAL GOAL. Adding training goals has a nicer and smoother interface now. If you like the update, especially the Breakdown and Share features, tag us on Instagram at @‌theoutsiders.app or on X at @‌theoutsidersapp Enjoy the outside!

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.

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.

Nice app and modern interface

Waiting for it to mature now

Grundsätzlich super Idee

Anfangs fand ich die App wirklich super. Mittlerweile habe ich festgestellt, dass die Daten aber nicht stimmen. Die Herzfrequenz im Schlaf sowie die Herzfrequenzvariabilität stimmen nie mit den tatsächlichen Daten im Handy überein und werden jedes Mal schlechter dargestellt wie sie eigentlich sind.
Mittlerweile leider ein Grund, die App zu deinstallieren.
