VitalGauge — Your Body's Dashboard for Pebble Time 2

VitalGauge is a fully autonomous, 100% offline health and recovery suite built specifically for the Pebble Time 2. Designed for privacy, battery efficiency, and meaningful physiological insights, VitalGauge transforms your watch's heart rate, heart rate variability (HRV), movement, and sleep measurements into an intuitive picture of your body's activity, stress, recovery, and estimated energy reserves.

No accounts. No subscriptions. No cloud processing. Just your health insights, right on your wrist.


ENERGY RESERVE & MORNING RECOVERY
Understand how your body responds to the demands of everyday life.
Energy Reserve combines sleep quality, recovery, cardiac efficiency, physical exertion, and physiological stress into a dynamic 0–100 score estimating your available energy.
Energy Contributors provides a colorful perimeter visualization showing how recovery, cardiac response, activity, and stress influence your current Energy Reserve.
Morning Recovery evaluates how well your body recovered overnight using sleep quality, resting heart rate, and HRV measurements.
Personalized HRV Baseline establishes your individual HRV reference through a seven-day calibration process, making your measurements more meaningful over time.

COMPREHENSIVE ACTIVITY & SLEEP TRACKING
Go beyond basic step counting with detailed visualizations of your daily physiological patterns.
Activity Tracking monitors daily movement, step progress, and activity patterns throughout the day.
Advanced Sleep Analysis combines native Pebble sleep detection with movement and heart-rate information to identify sleep periods, brief awakenings, and estimated sleep stages.
Sleep Architecture visualizes Deep, Light, and Awake periods using VitalGauge's signature perimeter graphs.
Historical Trends lets you review seven-day trends across Energy Reserve, Sleep, Stress, and Activity.
Persistent Health Data keeps your previous measurements available when reopening the app, even before new information finishes refreshing.

INTELLIGENT STRESS & HRV MONITORING
Understand how your body responds to physiological stress through personalized heart-rate variability analysis.
Native HRV Measurements calculate RMSSD heart-rate variability directly from the Pebble Time 2's pulse-to-pulse interval data.
Automatic Background Monitoring uses a lightweight background worker to identify suitable resting conditions and sustained heart-rate changes.
Automatic HRV Scans collect measurements during qualifying resting periods without requiring you to manually launch the app.

HRV Quality Filtering rejects questionable pulse intervals and unreliable readings to improve measurement consistency.
Personalized Stress Assessment compares HRV measurements against your individual baseline to help identify potential physiological stress.
Manual Stress Scans let you initiate a dedicated 60-second measurement whenever you want to check your current condition.

GUIDED BREATHING & PERSONALIZATION
Take an active role in your wellness with accessible tools and a customizable interface.
Guided Breathing provides a five-minute breathing exercise featuring animated pacing rings and audio cues.
Customizable Appearance offers Light and Dark modes, adjustable haptic feedback, breathing styles, and backlight settings.
Touch-Based Navigation provides intuitive access to health dashboards, detailed measurements, and historical trends.
Pebble-Native Design combines colorful dashboard rings, edge-to-edge perimeter graphs, readable typography, and straightforward navigation.

BUILT FOR PRIVACY & BATTERY EFFICIENCY
Your biometric information belongs to you.
100% Offline Operation means health tracking, calculations, and visualizations run directly on your Pebble Time 2.
On-Device Health Processing keeps your measurements stored and processed locally without requiring external health servers.
Incremental Health Synchronization reuses cached measurements and retrieves only missing history, with a small overlap, instead of repeatedly requesting the entire day.
Battery-Conscious Operation reduces unnecessary processing, redundant health queries, and persistent-storage writes.
No accounts, subscriptions, cloud synchronization, or external servers required.
