Most BAC calculators give a boring, static number. This app uses a detailed Widmark formula variation to map your metabolization curve over time. Enter your drinks and physical stats to get a real-time projection of your Blood Alcohol Content, a hangover forecast, and your current drinking "Alter Ego" (like The Karaoke Champion or The Chaos Generator). It even includes a Phone Risk Indicator to warn you before you text your ex!

Hey Product Hunt! 👋 I built My Hangover because I was tired of generic BAC calculators that just give you a static number and don't factor in the actual timeline of a night out. I wanted a tool that didn't compromise on the math, so this uses a detailed variation of the Widmark formula to map your metabolization curve. The trade-off is that it requires a bit of detailed data entry (drinks, food, water, sleep), but the result is a highly accurate hangover forecast and a brutal reality check on your current "Alter Ego" (like The Karaoke Champion or The Chaos Generator). I also just pushed a live update to include a lbs/kg toggle based on some early user feedback, so it's fully localized now! I’ll be here answering questions. Let me know what Alter Ego you end up with, and please don't ignore the Phone Risk Indicator!
