When Will I Be Sober?

Features & Capabilities

Are you ok to drive? Track your alcohol level in real time, get notified when you're clear to drive, predict your hangover, and make smarter choices every night out

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.

The app is great. Only downfall is it slows overtime. About every 6 months I have to delete and redownload.

This app is far inferior to Green Light, which I used for years but for some reason is no longer available. I know this app only cost $.99, but that is actually too bunch considering it is functionally useless.

This app has some nice features. My old favorite app, which hasn’t been updated in years, crashes frequently and it makes me incredibly sad. I’ve been looking for another app that will show me a graph of my estimated BAC and allow me to add multiple drinks. This app doesn’t feature the duration option, where I can show that I’ve been sipping on the same drink for an hour and therefore would alter my “time until sober”. That is my biggest issue with this app. I likely won’t use it until that feature is added but once it is, I can see this being a huge hit. The UI is nice looking and it’s easy to use. The other comment I have would be to fix the grammar on the banner. The sentences aren’t capitalized at the beginning and that’s just a bit picky thing that bring it down just a bit. Otherwise, keep updating developers, and I think this will be a great app to use in the future.
