Kanyasumi - Liver Rest Days

Drink, but rest too.

Kanyasumi is not a sobriety app. It is the simplest rest-day calendar for people who love drinking but want liver rest days — especially if your last health checkup made you think twice.

ONE TAP
Just tap "Drank" or "Didn't drink" each day. Drinking days turn amber, rest days get a green mark. Log servings per drink (0.5 steps, several kinds in one day) and pure alcohol grams are calculated automatically. Reorder the list so your usual drinks come first.

YOUR LIVER'S FACE
Based on your last 7 days, the liver face above the calendar changes across 5 stages. Keep resting and it brightens; keep drinking and it turns pale. (The face reflects your records only — it is not a medical diagnosis.)

CHECKUP NOTES
Track γ-GTP, AST, ALT and triglycerides over time, and set your next checkup date to see "X days until checkup" with reminders a week before and the day before. (No medical judgment is made — consult your doctor.)

BLOOD PRESSURE, MORNING AND EVENING
Log blood pressure and pulse twice a day, see 7-day and 30-day averages and trends, and share a month as a single table image for your doctor.

MONTHLY CARD
Your rest days, money saved and liver face in one shareable card. The one-time support plan adds liver outfits such as a headband or an onsen towel.

OUR PROMISE
