What’s New in 1.7 This update fixes two issues related to daily stress insights and widgets. Daily complications and widgets now calculate stress averages consistently with the main app, improving accuracy and avoiding discrepancies between views. We’ve also improved the Daily Average chart by adding subtle visual markers, making it easier to understand stress levels at a glance.

What’s New in 1.6 This update improves stability, accuracy, and overall performance across the app. We fixed an issue where the interface could refresh unexpectedly and occasionally cause crashes in certain situations. The internal stress detection algorithm has also been improved using updated scientific evidence based on age and sex ranges, helping provide more accurate and personalized stress estimations. Finally, the overall experience should now feel smoother and more fluid throughout the app.

What’s New in 1.5 This update focuses on polishing the experience and fixing small issues to make the app more reliable. We’ve resolved a bug affecting smaller Apple Watch models where text in one of the complications could be cut off. Now it displays correctly, including the measurement time in a clear 24-hour format.

What’s New in 1.4 This update focuses on small but meaningful improvements based directly on user feedback. Watch face widgets have been enhanced and now show the time of your last measurement, giving you more context at a glance. We’ve also improved performance when opening the app for the first time and fixed two known bugs to make the experience smoother and more reliable.

Say hello to Liquid Glass — What’s New in 1.3 This update brings a refreshed and more professional look with the return of the original Stress Tracker app icon. We’ve also redesigned the interface to match Apple’s new Liquid Glass design in watchOS 26. The app will feel familiar, but with a sleeker, more modern look. Other improvements include fixes for minor issues reported by users and a more accurate recovery algorithm for clearer daily insights.

What’s New in 1.2 This 1.2 update builds on the improvements introduced in version 1.1 — including smarter stress algorithms based on age and gender, and the launch of Moodles, your personal stress avatars. Now, we’ve fine-tuned how stress levels are labeled. Previously, a score of 6 might be flagged as “high stress,” which could be misleading. Labels have been updated to more accurately reflect the 1–10 stress scale, giving you clearer, calmer insights. We’ve also expanded language support: Stress Tracker is now available in French, Brazilian Portuguese, Japanese, Italian, and Russian — in addition to English, Spanish, German, and Chinese.

This 1.1 update brings three major improvements: • Meet Moodles, think of them as your personal stress avatars, helping you understand how you feel at a glance. • The stress algorithm has been improved using clinical studies that account for age and gender, offering much more accurate estimations—especially for older users. • Third, the app is now available in four languages: English, Spanish, German, and Chinese. We’ve also optimized battery usage and improved widget visuals and performance.
