What's New in Senstream
1.2.3
February 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
