Description

Turn your smartwatch into an advanced, standalone biometric engine. Completely rebuilt for V2.1, VitalGauge moves beyond basic step counting to give you a holistic, real-time view of your central nervous system.

By analyzing your heart rate variance, sleep architecture, and daily exertion, VitalGauge calculates your Energy Reserve—a dynamic "body battery" that drains when you are stressed or active, and actively recharges when you sleep or perform guided breathing.

100% offline. No cloud accounts. No battery drain. Just your data, beautifully visualized on your wrist.

🌟 Key Features
🔋 The Energy Reserve Hub
Glance at the 3-Ring Hub (Activity, Sleep, Stress) to see your day at a macro level. In the center is your live Energy Reserve (0-100%). It calculates your starting charge based on how you slept, and actively drains throughout the day based on your calorie burn and stress levels.

🧘 Live EKG Scanning & Guided Breathing
Tap into the Stress Dashboard to take a live, 60-second heart rate variance scan. If your stress is high, use the physical buttons to launch an interactive breathing session. Choose between Box Breathing (4-4-4-4), Relax (4-7-8), or Sleep (4-8) styles, complete with adjustable audio cues leveraging the built-in speaker. Successfully lowering your heart rate will actively reduce your stress penalty and recharge your Energy Reserve!

🛌 Advanced Sleep & Morning Readiness
Pebble's native sleep tracking is good; ours is better. VitalGauge uses a custom hybrid algorithm to strictly map your exact sleep boundaries, cross-referencing it with deep sleep data. Every morning, it checks your lowest heart rate during the 2 hours after you wake up. If you wake up stressed, your "Readiness" score takes a penalty, giving you a true morning baseline.

📊 On-Device 7-Day Trends
Leave your phone in your pocket. The dedicated Trends dashboard lets you use your watch's hardware buttons to cycle through beautiful, 7-day historical bar charts for your Energy, Sleep, Stress, and Activity goals.

🤫 Silent Background Monitoring
Health tracking shouldn't be intrusive. VitalGauge runs silently in the background, monitoring your heart rate against your physical movement. If it detects a severe stress spike while you are sitting completely still, it pushes a native, silent "Stress Spike" alert directly to your watch's system tray for you to review when you are ready.

⚡ Built for Battery Life & Privacy
100% Offline: All math, algorithms, and 7-day history arrays are processed and stored locally on the watch.

On-Demand Engine: VitalGauge does not constantly chew through your battery with background processing. It fetches and crunches your health data instantly only when you open the app or force a manual sync.
