1月31日 的 Always-On Heart Rate 應用程式分析

This Wear OS application shows the following metrics while keeping the device awake: • Heart rate (bpm). • Time (hours and minutes). • Duration (minutes and seconds). • Average and maximum heart rate for the last 60 seconds. • Battery percentage. Gesture Control: • Swipe left to open Settings to customize your experience. • Swipe right for the History tab, showing the maximum and average heart rate for 1-minute intervals and for the whole workout. • Swipe up to change font color to white and increase thickness for better readability in sunlight (increases power consumption). • Swipe down from the middle to check power consumption (~8%/hour on a 44mm Galaxy Watch 6). • Tap to enlarge heart rate font. Text-to-Speech: • The app can read your heart rate aloud when it exceeds user-defined HRmax or HRmin limits. • Tap the screen to hear the current time. • Supports most languages. Important Notes: • Optimize your workout by setting HRmax and HRmin. The app alerts you with visual, audio (beeps, voice), and tactile notifications every 2 seconds when HR exceeds HRmax or drops below HRmin. • The duration metric can either show the total time or only the time when your heart rate exceeded the HRmin limit, based on your preference. • Set HRmin to 95% of your resting HR to wake you up if you fall asleep. • All values update every second, except battery percentage and time (once a minute). • The display stays on until you quit the app. • For uninterrupted use, disable Samsung Health workout detection. Power-Saving Features: • Minimal UI design. • No internet or GPS usage. • You can quickly pause or resume the heart rate sensor and timer between exercises. • Only the green subpixels are used to reduce power consumption. • Adjust brightness using the rotating bezel or crown. • Numbers shift up or down the screen in the first second of every minute (e.g., 11:05:00, then 11:06:00, etc.) to prevent screen burn-in and give a better sense of time.
