## What is PulseBrew?

PulseBrew is the intelligent pour-over coffee companion designed for baristas and specialty coffee enthusiasts who demand precision and consistency. Never guess your flow rate again—turn any gooseneck kettle into a digital smart brewing tool.
By leveraging real-time acoustic resonance analysis through your iPhone's microphone, PulseBrew tracks your water flow rate and pouring consistency as water hits the coffee bed—without requiring expensive or bulky Bluetooth smart scales.
KEY FEATURES:
• Acoustic Flow-Rate Tracking
Instant, on-device audio spectral analysis guides your pouring stream to match optimal extraction curves. All audio processing runs 100% locally in volatile RAM and is never recorded, stored, or transmitted off-device.
• Real-Time Canvas Visualization
Experience smooth 60fps Bézier flow-rate curve tracking with interactive target baseline guidance to train professional pouring muscle memory.
• Live Activities & Dynamic Island
Keep your phone on the counter next to your dripper. Monitor stage countdowns and pouring metrics directly on your Lock Screen and Dynamic Island without touching your device.
• Multi-Dimensional Flavor Radar
Log and evaluate every brew session with an interactive 5-axis flavor profile (Acidity, Sweetness, Bitterness, Body, Clarity) to scientifically dial in your grind size and temperature.
• Multi-Device CloudKit Sync
Your custom multi-stage recipes and brewing journal sync seamlessly and privately across all your Apple devices via your personal iCloud container.
