TEKNOFEST 2026 finalist. A wristband and mobile app that catch gambling-craving waves: if heart rate and skin conductance rise together with risky phone use inside the same 3-minute window, an intervention screen opens. Raw data never leaves the phone.

ESP32-S3 wristband measuring heart rate, skin conductance, skin temperature and motion
The app watches the foreground app through Android's accessibility service; when both signals rise together, a 3-level intervention starts
No server: raw data is processed on the phone and discarded, only the triggered level and its time are kept
The app is installed on a real phone, and the fusion engine and physiological layer pass 14 unit tests. The wristband is not built yet
