About

I'm Kou, an indie iOS developer based in Japan, building under the brand kouworks. I focus on small, focused apps that solve real problems for creators and travelers — with a strong emphasis on privacy and on-device processing. Recent apps include RekiMap (a historical map app for travelers in Japan), ListenBack (an audio playback tool), and most recently VlogMask, a real-time face mosaic camera app for vloggers who film in public. I believe the best software comes from solving your own frustrations. Every app I ship is something I personally wanted to exist. Always happy to connect with fellow indie devs, creators, and anyone interested in privacy-first apps. → kou-works.jp → contact@kou-works.jp

VlogMask - Tap to protect your face. Mosaic everyone else.

VlogMask is an iOS camera app that mosaics every bystander's face in real time while you record. Tap your face to protect it — everyone else gets pixelated automatically. No post-editing. On-device processing only. Built for street vloggers, travel creators, and anyone who films in public.
