Sereno

The application reads biometric, sleep, activity, and contextual data collected by an Apple Watch and stored in Apple Health, then combines more than twenty signals into a single stress score that updates throughout the day. It presents the score in plain language, offers weekly reports that highlight patterns between meetings, movement, and rest, and supplies guided box‑breathing exercises—including customizable 4‑7‑8 routines—intended to lower the score when it rises.

When the score reaches an elevated range, the interface shifts to prioritize a breathing reset and provides one‑tap access to offline crisis‑support hotlines for twelve countries. All processing occurs on the user’s device, and the tool is positioned as a wellness aid rather than a medical diagnostic or treatment system.

The workflow consists of three steps: wear the Apple Watch as usual, read the daily stress insights in the app, and initiate a reset when needed. The product is in an experimental stage and has been tested by over five hundred beta users.
