Description

BAC2Sober is a premium, real-time blood alcohol tracking companion for your Pebble smartwatch. Built with a focus on speed, privacy, and native Pebble aesthetics, it utilizes the trusted Widmark formula to dynamically calculate your current BAC and estimate the exact time you will be completely sober.

Whether you are sipping a craft taster or splitting a full bottle of wine, BAC2Sober makes logging your drinks effortless.

Features:

- Real-Time Tracking: A live dashboard tracks your current BAC and continuously updates your "Sober By" countdown every minute using the system tick timer.
- Built-In Watchface: Check your current BAC and countdown to sobriety directly from your wrist without needing to launch the app.
- Dynamic Geometric Graphics: Watch your drinks fill up on the screen! Native 2D vector graphics beautifully replicate standard cans, tallboys, bottles, growlers, wine glasses, and shots—keeping the app incredibly fast and lightweight.
- Precision Logging: Dial in exact volumes (Metric or Imperial) and ABV percentages down to 0.1% for maximum accuracy.
- Timeline Integration: Optionally push a notification pin to your Pebble Timeline when you mathematically hit a specific Target BAC (e.g., 0.05% or 0.00%).
- Theme Engine: Fully supports Dark, Light, and Auto modes to match your watch's hardware, highlighted with vibrant UI colors on modern displays and clear high-contrast layouts on monochrome screens.
- Accessibility: Fully respects system-wide Pebble OS text size preferences (Large/Small) so text dynamically scales to match your readability settings. Fully touch-enabled interface including a 'back' gesture (for PT2 and PR2). 
- Privacy First: 100% of your data remains locally on your wrist. No accounts, no cloud sync, no tracking.
