# CatVerse Lab

> CatVerse Lab is an independent app studio that crafts joyful, beautifully designed mobile apps: CatVerse (cat games for iPhone, iPad and Android), Cathena (an AI photo studio and cat-care assistant) and VISEFF (AI photo effects that keep your face and pose). Every app is free to download on the App Store and Google Play, beautifully designed and built with respect for privacy.

CatVerse Lab designs, builds and cares for every app itself. Our apps need no account, AI features ask for consent before sending anything, and each app has a plain-language privacy policy. Contact: hfl.athena@gmail.com.

- [VISEFF](https://catverselab.com/viseff): VISEFF turns one photo into AI effects, portraits, photo booth strips, magazine covers and outfit changes in about 15 seconds, while keeping your face and pose exactly as they are. It also includes free on-device tools: AI Eraser, background removal for stickers, blur, text, filters and crop.
- [Spirun](https://catverselab.com/spirun): Spirun is a calm running app for Taiwan: run or walk in a park or on a track and you may collect nature spirits drawn from real habitats, each with a runner's motto and real conservation facts.
