Ok To Drive vs Designated

Know your limit. Own your night. We use a medically-informed algorithm — designed alongside doctors — to estimate your Blood Alcohol Content (BAC) in real time, based on your weight, gender, drinks consumed, food intake and fatigue. How it works Enter what you're drinking and we do the math. Your BAC updates as the night progresses, giving you a clear picture of where you stand — green, yellow, or red. What is BAC? Blood Alcohol Content is the percentage of alcohol in your bloodstream. It peaks 30–70 minutes after drinking. Despite what you've heard, nothing lowers BAC except time — not coffee, not cold showers, not water. We'll tell you exactly when you're clear. What you get - Real-time BAC tracking with a traffic light system - Notifications when you're fit to drive again - Hydration reminders to stay ahead of the hangover - Hangover predictions so you know what tomorrow looks like - Multiple user profiles — track the whole group - A calendar view of your drinking habits over time - A home screen widget so your BAC is always one glance away - A full drink library plus custom drink builder A word of honesty Everyone metabolizes alcohol differently. This app gives you a well-informed estimate — not a guarantee. Never use it as the sole basis for deciding to drive. I built this because I believe people make better choices when they have better information. Consider this your smarter drinking companion, not a substitute for medical advice.

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.
