## What is Unbuzz?

Caffeine has a 5-hour half-life. A coffee at 3 pm is still circulating in your bloodstream at midnight, and that's why you can't sleep. Unbuzz tracks every drink, models your personal caffeine decay, and tells you the exact moment you're sleep-ready.

SLEEP-READY ALERTS
• Real-time caffeine curve based on your personal half-life
• A gentle notification when your level drops below your bedtime threshold
• Customisable bedtime goal, drink portion sizes, and sensitivity factors

SMART TRACKING
• Quick-tap logging for your favourite drinks
• Barcode scanner for canned and bottled drinks
• Apple Health integration (read & write)
• Offline-first: every measurement stays on your device by default

INSIGHTS
• Daily and weekly caffeine breakdown
• Streaks and achievements that reinforce mindful habits
• Trends you can finally tie back to how you slept

UNBUZZ PRO
• Apple Watch app + complications, log a drink from your wrist
• Home Screen and Lock Screen widgets that show your live caffeine level
• Siri Shortcuts for voice logging ("Hey Siri, I just had a coffee")
• Sleep-correlation analytics (how each day's caffeine maps to your night)
• Weekly and monthly trend reports
• Guided tolerance-reset programs (one of the most common asks)
• Cloud backup and sync across your devices
• Available monthly, yearly, or as a one-time Lifetime purchase

PRIVACY
• Works fully offline by default
• Optional cloud sync uses end-to-end encryption
• No third-party tracking, no ads, no data sales
