DESIGNATED — THE FIRST PASSIVE IMPAIRMENT DETECTOR Your phone already knows how you walk. Designated uses that to keep you safe. Unlike breathalyzers or drink-counting apps that need you to do something while impaired, Designated works silently in the background. It learns your sober walking pattern, then detects when something changes — and helps you get home. HOW IT WORKS 1. Calibrate once — Take a 60-second walk. Designated learns your unique gait baseline. 2. Go about your night — The app monitors passively using your phone's motion sensors. 3. Get alerted if needed — If your walking pattern changes, you'll know before you get behind the wheel. 4. Get home safely — One tap to request an Uber or Lyft with your home address pre-filled. INTELLIGENT DETECTION • Personalized baseline adapts to YOUR walking pattern — not a generic model • Multi-signal analysis combining gait, cognitive, and behavioral patterns • Three-tier escalation: gentle nudge → persistent alert → emergency contact notification • Smart dismissal requires biometric auth to prevent impaired override • Real-time confidence scoring that updates continuously 11 SOBRIETY TESTS When you want to check yourself: • Reaction Time — Tap speed across 5 rounds • Stroop Test — Cognitive interference detection • Balance — Postural sway analysis • Hand Tremor — Involuntary movement detection • Eye Tracking — Smooth pursuit evaluation • Voice Analysis — Speech pattern assessment • Finger Tracing — Fine motor coordination • Go/No-Go — Impulse control testing • Facial Symmetry — Muscle control analysis Plus a full drink logger with real-time BAC estimation using the Widmark formula ONE-TAP RIDES HOME • Uber and Lyft integration built in • Home address pre-filled — one tap and your ride is coming • Designated driver SMS with your live location • Rides requested directly from alerts SAFETY NETWORK • Pair watchers who monitor your status in real time • Trusted contacts get automatic SMS alerts with your location • Three escalation tiers ensure the right people know at the right time • Group mode for nights out with friends • Pre-commitment pledges — plan your safe ride before you go out PRIVACY FIRST • ALL processing happens on your device. No servers. No cloud analytics. • Raw sensor data is never stored — extracted and immediately discarded • No tracking. No ads. No data selling. • Impairment data never leaves your phone unless YOU alert a contact ALSO INCLUDES • Live Activity on Lock Screen showing real-time status • Home Screen widget for at-a-glance monitoring • Morning-after reports summarizing your night • Confidence timeline charting your evening • Venue detection and smart watch windows • Parking location reminder for the morning after IMPORTANT Designated is a wellness awareness tool. It does not measure blood alcohol content. It is not a medical device or breathalyzer. Never rely solely on this app to determine fitness to drive. When in doubt, don't drive. ## Version history (last 3 releases) ### 1.50 — 2026-07-02 marter Diagnostics Crashlytics now captures CPU, disk, and launch call stacks from MetricKit for deeper crash analysis Post-crash logs are automatically forwarded as breadcrumbs for faster triage Thermal state is correlated with hang reports to identify heat-related performance issues Session-level crash-free rate tracking Improved Detection Accuracy Fixed a state machine race where stopping monitoring during an active sample could leave the engine in an incorrect state BAC estimates now handle clock-drift scenarios correctly instead of silently dropping drinks CloudKit watcher check-in failures are now logged and reported instead of silently ignored Accessibility & UI Onboarding headings now scale properly with Dynamic Type Added missing VoiceOver header traits to section headers throughout the app Drink detail text no longer truncates at larger text sizes Privacy Hardening Biometric baselines (typing speed, tap precision, walking steadiness) are now redacted from system logs Watch window schedule times redacted from diagnostic logs Performance Instrumentation Wired performance signposts for CloudKit sync, calibration walks, and notification delivery MetricKit metadata (region, architecture) and disk I/O now tracked per signpost ### 1.25 — 2026-06-09 Here's the release notes for 1.1.0: --- **Impairment-Aware UI** The entire interface now adapts in real time to your state. As impairment confidence rises, touch targets grow larger, fonts increase, and non-essential controls fade away — so the actions that matter most (getting a ride, reaching a contact) are always easy to find and tap. **Redesigned Settings, Tests & Watcher Dashboard** Settings, sobriety test menu, and watcher dashboard have been rebuilt with the adaptive UI system. During elevated states, advanced options are hidden automatically and only safety-critical controls remain visible. **Science-Based Color Palette** Every color in the app has been re-tuned based on alcohol vision research. Blue undertones removed from dark-mode backgrounds, warm amber and high-contrast text throughout — designed to stay readable even when your color perception is compromised. All safety colors (red, amber, green) now meet or exceed WCAG AA contrast standards. **Stability & Performance** - Resolved all compiler strict-concurrency warnings across both iPhone and Apple Watch targets - Improved actor isolation for CarPlay, keystroke dynamics, and sensor pipeline - Fixed MetricKit call-stack parsing and Crashlytics device identification - Version management streamlined for faster future updates ### 1.0 — 2026-05-15 No release notes. ## More apps by Honorius Neogy - [ConvoAct ADHD & Autism Planner](https://appshunter.io/ios/app/convoact-adhd-and-autism-planner/id6754623039) - [ConvoAct: ADHD Focus & Habits](https://appshunter.io/ios/app/convoact-adhd-focus-and-habits/id6758873134) - [WakeAct — Puzzle Alarm Clock](https://appshunter.io/ios/app/wakeact-puzzle-alarm-clock/id6760993737) - [BudgetAct](https://appshunter.io/ios/app/budgetact/id6761248828) - [Ugh!
