awareness.
Sipora estimates your blood alcohol content (BAC) and tracks your drinking sessions — so you stay informed, not guessing. A calm, private tool with no cloud dependency.
Sipora provides estimates only. Not medical advice. Not legal advice.
What Sipora does
BAC Estimation
Estimates blood alcohol content using the Widmark formula, based on drinks consumed, body weight, elapsed time, and biological sex.
Session Tracking
Log drinks as you go. Track session duration and cumulative intake in real time.
Legal Limit Awareness
Compare your estimated BAC against common legal driving limits. Always informational — not a legal determination.
Time Calculator
Estimate how long until your BAC returns to zero based on your current session data.
Drink History
Review past sessions to understand your patterns over time. All data stored locally on your device.
Privacy First
No account required. No cloud sync. No analytics. Everything stays on your device.

Why Sipora
Sipora is not a medical tool. It doesn't certify sobriety, authorize decisions, or claim precision. It's a practical awareness tool — designed to give you useful estimates, not to tell you what to do.
Every BAC reading is an estimate influenced by variables the app cannot measure: individual metabolism, food intake, health conditions, and more. The app gives you a number to think with, not a number to act on blindly.
The goal is awareness, not false certainty. Use it to understand your patterns and make better-informed personal choices.
Built by one person
Sipora is an independent project. If it's useful to you, consider supporting its development.
