About this app

Nyanlog is a new cat diary app that lets the whole family record their beloved cat's daily life.

Simply take a photo, and the AI ​​will tell you what your cat is feeling. Preserve the little expressions and gestures of your precious family member every day.

[Main Features]

◆ Daily Record "Nya-u"
Record your cat's mood, photo, comment, and tags in 30 seconds. It's simple, so you can keep it up every day.

◆ AI Mood Diagnosis
The AI ​​observes your cat's photo. It translates their feelings for the day into words based on their expressions, gestures, and posture. A great way for the whole family to communicate, saying things like, "So this is how our cat was feeling right now!"

◆ Family Sharing
You can record the same cat's life together with your partner, children, grandparents, and others. When someone posts, it instantly appears on everyone's screen. You can share daily updates even with family members who live far away.

◆ Comments and Likes
Comment on posts and send likes to each other. You'll receive notifications in real time.

◆ Calendar View
View past posts in a calendar format. Easily recall how many days before your birthday it was, and how you felt on that day.

Even if you have more than one cat, you can keep separate records for each.
