New in v1.5.0 • Always-Visible Hypertension Graph – Blood pressure graph is now permanently displayed on the main screen – No longer hidden behind a modal or button – Shows a placeholder graph with reduced opacity when no readings exist yet – Automatically updates with each new reading – Color-coded zones: Low (cyan), Normal (green), Prehypertension (orange), Stage 1 (pink), Stage 2 (red) • Settings Persistence – User preferences are now saved between app sessions – “Save to Apple Health” toggle state is persisted – “Average (3 readings)” mode selection is persisted – Delay slider value is persisted (15s, 30s, 45s, or 60s) – Settings are restored automatically on app launch • Improved UI Layout – Streamlined interface with no shifting elements – Removed app icon from the main view to reduce clutter – Top bar now shows “LibreArm” on the left and “Blood Pressure” on the right – Status and battery information displayed on a dedicated line – Delay slider is always visible (disabled when not in Average mode) – Fixed layout prevents UI jumping when toggling settings • Enhanced Graph Integration – Hypertension classification graph embedded directly in the reading card – Proper axis labels (Systolic / Diastolic in mmHg) – Zone labels clearly positioned and left-aligned – Reading plot point includes a white border and shadow for better visibility • Version updated to 1.5.0

Battery Level Display: Real-time battery monitoring using standard BLE Battery Service (0x180F) Battery percentage shown in UI under connection status Low battery warning (≤20%) Critical battery alert (≤10%) Battery Notifications: Background notifications when battery crosses low/critical thresholds (only when app is backgrounded) Critical Battery Protection: Measurements are blocked when battery ≤10% to prevent incomplete readings Clear warning message displayed Stop button remains functional during ongoing measurements Strict Reading Validation: Enhanced data quality control Invalid or incomplete readings are no longer displayed or saved to Apple Health Readings validated for physiological plausibility (ranges, systolic > diastolic, pulse pressure) Clear warning messages when measurements fail validation Average Mode Improvements: Requires all 3 readings to be valid If any reading is invalid, the entire average session is rejected No partial averages saved to Health User prompted to retry if session invalid Automatic Battery Checks: Battery level read on connect, before measurements, and after completion Version updated to 1.4.0 Special Thanks: v1.4.0 was inspired by valuable community feedback: Battery percentage monitoring suggested by ashok-raj (https://github.com/ashok-raj) Inaccurate reading validation improvements suggested by stacksjb (https://github.com/stacksjb)

• Added a new delay slider — choose a 15, 30, 45, or 60-second pause between readings in Average Mode • Improved Average Mode clarity and accuracy, with better handling of invalid readings • Updated controls: all toggles and sliders are now disabled during active measurements to prevent accidental changes • Enhanced stability and reliability of multi-run sessions • General performance and UI improvements

• New Average Mode: the app now performs 3 readings spaced 10 seconds apart, and saves the averaged result • Live countdown display between runs (“next in Xs…”) • Stop button stays red and active until the entire 3-run sequence completes • Screen no longer sleeps during measurements • Added version label in the app footer for clarity

What’s New in Version 1.1.1 • Improved reliability when saving to Apple Health — readings are now only saved once a full blood pressure measurement is complete. • Minor fixes and stability improvements.
