Store description excerpt

This app helps you estimate when your blood alcohol level may be below your selected country's driving limit. Fully free to use — no subscriptions or hidden costs.* Choose your country, record drinks and follow an estimated timeline showing how alcohol may change throughout the day or night. The app focuses on timelines, transparency and cautious estimates, helping you understand how alcohol may rise and reduce over time using a safety-first approach. View your estimated alcohol timeline, record drinks quickly and see estimated key times including when you may be below your selected driving limit.
