About
RESEARCH RING: LAB GRADE PHYSIOLOGICAL DATA ACQUISITION PLEASE NOTE: The Senstream Researcher Ring is not a medical device and is not intended to diagnose, treat, cure, monitor, or prevent medical conditions or illnesses. The app is designed to record physiological signal data, but not to make medical decisions. Multi-Sensor: Electrodermal activity (EDA, aka GSR), ECG, PPG, temperature and motion, captured from a single, user friendly device with long battery life. Electrodermal Data: Our initial product is the first ring form factor device that captures electrodermal activity with lab quality, enabling new types of research. ECG and/or Pulse: Capture electrocardiograph (ECG) and/or photoplethysmograph (PPG) data, depending on the specific needs of a study or application. Temperature and Motion: Capture temperature data from the finger, and contextualize physiological data with motion data captured by the Research Ring. Mobile and Cloud Apps: Start capturing data with just a ring and mobile app, which seamlessly connects to the cloud. BIOPAC integration offers powerful tools. Bold Vision: The Senstream roadmap, supported by a rich patent portfolio, leverages the convenience and unique physiology of the finger. Stay tuned!
What's New
Version 1.2.3 • Feb 4, 2026
Siri, Spotlight & Shortcuts Integration - Added App Intents: check ring status, start/end sessions, and flag events using Siri, Spotlight, or the Shortcuts app - Configurable Siri phrases like "Check my Senstream ring" and "Start Senstream session" Live Activity Improvements - Fixed Lock Screen Live Activity using the wrong view on iOS 18+ — was incorrectly showing the Apple Watch layout instead of the iOS Lock Screen layout - Redesigned Lock Screen Live Activity layout with proper spacing, improved typography, and HIG-compliant margins - Fixed stale Live Activities persisting after force quit — activities are now cleaned up on app launch - Fixed Dynamic Island clipping by using compact sensor mode names and adding padding to prevent corner cutoff - Reverted compact Dynamic Island to original tight sizing around the sensor array Chart & Signal Fixes - Fixed live session chart window durations for all signal types (ECG, PPG, EDA, Temperature, Acceleration) with appropriate per-signal window sizes - Fixed accelerometer conversion to correctly handle signed 16-bit values — negative G-force readings were being misinterpreted as large positive values
