Hada Koyomi: Skin Journal

Record daily skin feelings, care, and optional context. Compare any two on-device photos and share a text-only recap—with no scoring, diagnosis, or photo upload.

A gentler way to keep track of the days you spend with your skin.

Hada Koyomi is a 28-day skin calendar for recording how your skin feels, morning and evening care, optional context, and photos taken with consistent conditions in mind.

It does not score your skin or diagnose photos. It helps you save small observations in your own words and reflect at a pace that feels comfortable.

TODAY'S SKIN IN 10 SECONDS Choose the feeling that fits today: calm, a little dry, feels warm, or needs care. Then mark morning and evening care.

THREE GENTLE STEPS FOR TODAY The app suggests three low-pressure, general care ideas based on the feeling you selected, such as gentle cleansing, familiar moisturizer, sunscreen, or reducing friction. They are not medical instructions.

OPTIONAL CONTEXT FOR EACH DAY Add context tags for things you noticed, such as sleep, masks, or sunlight. You choose every tag yourself. The app does not infer that a tag caused a skin change.

CHOOSE ANY TWO PHOTOS TO COMPARE Use a guide to repeat the same spot, angle, and distance. Take a photo with the camera or select one from your library. Choose any two saved photos and move the slider to compare them manually. The app does not analyze photos or determine effectiveness.

YOUR REAL SKIN CALENDAR Daily feelings, care records, notes, and photo days appear in a month-by-month calendar. Empty days remain empty—there is no demo history or invented score.

A 28-DAY REFLECTION Gather care days, photos, and personal notes into a gentle recap. Hada Koyomi does not declare an outcome or improvement percentage; it reflects only what you recorded.

TEXT-ONLY SHARING When you open the iOS share sheet, you can share a text summary of record counts and context you selected. Photos and your free-form reflection are excluded. You choose the destination and can cancel before sharing.

JAPANESE AND ENGLISH Switch the entire app between Japanese and English in Settings.

OPTIONAL LOCAL REMINDERS Choose morning and evening times. The app asks for notification permission only after you turn reminders on. Every journal feature remains available without notifications.

PRIVACY BY DESIGN No account is required. Skin entries and photos are stored on your device and are never sent to our servers. There are no third-party ads, ad tracking, face recognition, or automated photo diagnosis. Delete one photo at a time, or delete all records and photos from Settings.

All Version 1.1 features are free. There are no ads.

Hada Koyomi is not a medical device and does not provide diagnosis, treatment, or treatment-effect assessment. If you experience strong pain, a sudden change, or ongoing discomfort, consult a dermatologist or another qualified professional.
