## What is CalmQuake App?

CalmQuake detects the early signs of stress, irritation, and anxiety — before they escalate — and gently nudges you to pause and breathe.

■ What is CalmQuake?
Using Apple Watch's heart rate and motion sensors, CalmQuake identifies subtle physiological changes that often precede emotional spikes. It's not about logging moods after the fact — it's about catching them in the moment.

■ How it works
1. Start a monitoring session on Apple Watch
2. CalmQuake tracks heart rate changes and wrist motion
3. When a pattern is detected, a gentle haptic alert fires
4. Choose: breathe for 30 seconds, take a quick action, or snooze
5. Your "was this accurate?" feedback improves detection over time

■ Key Features
• Monitoring sessions: 15, 30, or 60 minutes
• 3-level intervention: light alert / breathing guide / action suggestions
• 30-second breathing: 4s inhale → 2s hold → 6s exhale × 3 sets
• Accuracy tracking via post-alert feedback
• iPhone dashboard: hourly trends and session history

■ Perfect for
• Staying calm in meetings and client interactions
• Parents wanting to manage frustration with children
• Anyone prone to anxiety before high-stakes situations
• People who want to catch stress signals before reacting
