• Improved GPS route accuracy during walking, running, and cycling workouts. • Speed display no longer gets stuck when you stop at lights or rest.

• Apple Watch: start outdoor workouts as Walk, Run, or Bike — each with its own activity type for accurate Apple Health stats. • Speed now drops cleanly to zero when you stop — no more stuck readings at traffic lights. • Watch-only workouts sync to iPhone more reliably, even after the app has been closed. • Tuned speed and route tracking per activity for walking, running, and cycling. • Recent workouts list now shows the correct activity name on each page.

Cardio Fitness Tracking： Cardio fitness trend on the calendar — toggle between average heart rate and cardio fitness for any day Automatically uses Apple Watch cardio fitness data when available, with an on-device estimate as a fallback Outdoor Activity： Map now auto-fits to your route for better viewing Improved distance and pace display for outdoor activities Cleaner list of recent outdoor activities Indoor Walking & Running： Improved pace and distance display when used with Apple Watch Stats now visible throughout your activity Apple Watch Companion： Opens directly into activity view for faster use Redesigned stop button with a hold-to-confirm progress indicator End-of-activity summary screen showing duration and distance Improved reliability when starting the app Better coordination between iPhone and Apple Watch General Improvements： Consistent hold-to-stop button across activity pages You can leave an activity page without interrupting it Faster app launch Smoother switching between different activity views Various UI polish and stability fixes

- New: Outdoor activity mode with real-time GPS route tracking and speed display - New: Indoor run mode with Apple Watch motion-based speed detection - New: Route map review with multi-track overlay comparison - New: Offline map tile caching for route viewing without internet - New: Apple Watch speed display for cycling and running with tap-to-toggle between speed and heart rate

- Faster data loading: analysis page opens instantly with BPM chart, ECG loads on demand - Improved ECG waveform display with envelope overview when zoomed out - Cross-day recordings now automatically split into per-day segments - Repaired historical recordings with missing data - Enhanced BPM chart with noise compression and better Y-axis scaling - Increased ECG zoom range to view individual heartbeats

• Fixed: v1.x paid customers now auto-unlock as Lifetime Member on launch. No need to tap Restore Purchase. • Long recordings are auto-split into activity segments (Rest / Office / Walking / Heavy Activity), shown as a color bar in Statistics. • Mode stats now count actual time spent in each mode, not whole recordings. • Import / Export shows a progress bar and completion message.

Added Terms of Use and Privacy Policy links to the subscription page Added Legal section in Settings

1 Subscription — ECG Suite now offers monthly and annual subscription plans. Existing users who downloaded the app before this update retain full lifetime access at no cost. New users get a 7-day free trial with full features. 2 Data Import/Export — Improved reliability of database backup and restore to ensure all ECG waveform and heart rate data are fully preserved.

1 Apple Health HRV Sync — When only Apple Watch ECG data is available, HRV metrics (SDNN) are automatically synced from Apple Health for improved results. 2 Smart HRV Tracking — HRV tracking now uses a multi-source priority system: Polar ECG data (best available), Polar+Watch cross-validation with divergence alerts, Apple Health sync for Watch-only recordings, and optimized BLE heart rate calculation as fallback. 3Improved Bluetooth Stability — Increased reconnection attempts (up to 10 with exponential backoff), continuous slow retry instead of disconnecting, and silent background audio keep-alive to prevent iOS from terminating BLE connections during long monitoring sessions. 4 Calendar Activity Filter — Daily average heart rate on the calendar can now be filtered by activity mode: All, Sleep, Work, Walk, or Sports. 5 UI Improvements — Streamlined toolbar layout across all pages, activity mode icons updated (sleep, work, walk, run), gauge needle pulses with heartbeat rhythm, and detailed health metrics now show normal ranges with wellness guidance.

1 Data Management — Users can now manually manage recording data from Settings. Added options to clean up old data by time range (1 month, 3 months, 6 months, 1 year, 2 years). Users can export and import database backups via the iOS share sheet to iCloud Drive, Files, AirDrop, etc. This allows users to back up and restore their personal health monitoring data across devices, ensuring full data portability. Automatic deletion of data older than 30 days has been removed — users now have full control over their data retention. 2 Improved Bluetooth Connection Stability — Significantly improved connection resilience for long-duration heart rate monitoring sessions. The app now retries reconnection more aggressively (up to 10 attempts with exponential backoff) and continues retrying indefinitely at slower intervals instead of giving up. Fixed a bug where BLE heart rate monitors could silently stop recording without triggering reconnection. Background audio keep-alive now runs in silent mode even when heartbeat beep is disabled, preventing iOS from terminating the Bluetooth connection during extended background sessions. 3 Calendar Activity Filter — The calendar page now allows filtering daily average heart rate by activity mode: All, Sleep, Work, Walk, or Sports.

Alcohol Tagging :Added a dedicated "Alcohol" toggle button on the BPM Monitor, Gauge, and ECG recording pages to easily tag your sessions. Fully supported on both iOS and Apple Watch. Health Data Isolation: Records tagged as "Alcohol" are now automatically grouped into an isolated category. They are excluded from your standard resting heart rate statistics and daily activity trends, ensuring your baseline health metrics remain pure and accurate. Dedicated Trend View: Added a new "Alcohol" filter chip in the continuous trend page, allowing you to specifically track and compare how alcohol consumption independently affects your heart rate over time. General performance improvements for the multi-view statistical charts and various bug fixes.

Added Apple Watch Support Apple Watch companion app now supports standalone heart rate monitoring Improved Watch ECG analysis accuracy with native 512Hz processing Stop on watch now correctly saves data on iPhone

• Continuous Background ECG Recording — ECG data now records reliably when the screen is off or the app is in the background, powered by a real-time heartbeat audio monitor. • Heartbeat Audio Monitor — A soft beep plays in sync with your heart rate during recording. The pitch rises with higher BPM, giving you audio feedback like a hospital monitor. • Bradycardia Alert — The app now alerts you immediately if your heart rate drops below 40 BPM. • Bug fixes and stability improvements.
