PulseBrew 1.0.1 delivers major performance, precision, and sensory logging upgrades to our acoustic pour-over companion: • Zero-Allocation vDSP Acoustic Engine: Re-engineered real-time audio pipeline using Hann windowing, dedicated water flow bandpass filtering (1.0–8.5 kHz), and EMA smoothing to eliminate background noise. Pre-allocated FFT buffers and optimized UI throttling ensure zero thermal throttling and rock-solid flow tracking. • Stage-Aware Target Guidance & Auto-Completion: Introduced intelligent flow-rate targets across pouring (2.5 g/s) and drawdown (0.0 g/s) stages. Active sessions automatically conclude, dismiss Live Activities, and save to your brewing journal upon reaching the 180-second mark. • 10-Minute Full-Session Curve Replay: Expanded historical persistence capacity up to 1,200 samples (10 minutes), capturing every bloom, pour, and drawdown phase in granular detail alongside smooth 30-second rolling Canvas charts. • Interactive 5-Axis Flavor Radar: Dial in post-brew tasting notes with dynamic sliders for Acidity, Sweetness, Bitterness, Body, and Clarity—seamlessly synced via SwiftData and private CloudKit. • Embedded Dynamic Island & Live Activities: Integrated native Widget Extension target supporting seamless, race-condition-free countdowns and live flow gauges on your Lock Screen and Dynamic Island. • Subscription & StoreKit 2 Integrity: Enforced strict entitlement expiration and revocation validation across restore and purchase verification pipelines. • Performance, Accessibility & Reliability: Accelerated database operations with SwiftData #Predicate queries, added full VoiceOver accessibility labels across charts, normalized navigation stacks, and integrated structured os.Logger diagnostics.
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. --- PULSEBREW PRO SUBSCRIPTION: Upgrade to PulseBrew Pro ($2.99/month) to unlock: • Unlimited multi-stage recipe presets • Complete historical acoustic flow curve replay • Advanced multi-device CloudKit backup & sync • Full flavor radar analytics & data export Subscription Information: • Payment will be charged to your Apple ID account at confirmation of purchase. • Subscription automatically renews at $2.99/month unless canceled at least 24 hours before the end of the current period. • Your account will be charged for renewal within 24 hours prior to the end of the current billing cycle. • You can manage and cancel your subscriptions in your App Store Account Settings anytime after purchase.
