ShiftSense

Contactless clinician wellness check-ins powered by Presage vitals sensing and Gemini AI.

ShiftSense is an iOS app that uses your device's front camera to run 15-second physiologic check-ins during a clinical shift. It translates raw pulse and breathing data into plain-language insights, tracks wellness trends across a shift, and surfaces recovery actions before strain compounds.

What it does

• 15-second contactless scan — uses the Presage SmartSpectra SDK to measure pulse rate and breathing rate via front camera, no wearables required
• Gemini AI interpretation — each check-in generates a personalized clinical-style insight via the Gemini 1.5 Flash API, contextualized to shift type and prior strain history
• Shift-aware trend tracking — check-ins are grouped by shift (Day / Evening / Night) and stored persistently, surfacing cumulative strain patterns not visible from a single reading
• Adaptive recovery plan — recovery guidance adjusts based on wellness level (Calm / Elevated / Strained) and escalates if strain repeats across the shift
• Sustainability focus — uses existing device hardware instead of dedicated wearables, reducing cost, e-waste, and procurement burden for healthcare systems
