Widmark estimate based on drink volume, ABV, body weight and time, assuming the drinks are spread across the window. Legal limits vary: 0.2‰ in much of the EU, 0.8‰ in the US & UK. Individual results differ — this is not a legal or medical reference, and never a reason to decide whether to drive. The full experience — live tracking, group seshes, recaps — lives in the Sesh app.
