What it does
-
Logging you can do tipsy
Tap the picture of your drink once. From the second glass, “Another” logs the same again. Pick the size in everyday words like a medium mug or one gō — or just “Not sure”.
-
When it wears off
From what you drank and your body size, it estimates when the alcohol wears off as three times — early, typical and late — with an illustrative graph.
-
Stop before it's too much
A quiet note when you pass the amount in Japan's drinking guideline or drink fast. Log water with one tap, and get a hint of how much and when.
-
Lock Screen and Dynamic Island
Log from the Live Activity, Control Center or Siri, and check the time left without opening the app.
-
On Apple Watch too
Log from your wrist with one tap. Time left, another round and water — all there.
-
Last-train support (optional)
Register your home, and on a night out it finds the last train from a nearby station and shows when to leave on the Lock Screen. Times are estimates and don't reflect same-day delays.
