The app Last Call was legendary. ### 1/5 — Check your math *2025-08-18* You have the US legal limit at 0.8. It is .08. I doubt this app is any good in US units to say the least. **Developer response:** Hi, thanks for reaching out. The app uses the per mille (‰) unit for BAC, where the US limit is 0.8‰. This is the mathematical equivalent of the 0.08% standard. I'll look into making this distinction clearer in a future update to avoid confusion.
