A — Overview
One calm app instead of five
Sleep sounds, meditation, breathing exercises and habit tracking usually come as separate apps. StillKoi brings them into one product, built around something most meditation apps don’t have: a mixer for layering natural sounds into your own soundscape. You can use that soundscape on its own or alongside guided sessions, breathing and daily rituals.
It was a solo project. I came up with the idea and the name, designed the brand and UI, and built the mobile app, backend, database and website. I also took both store releases through review. StillKoi has been live on the App Store and Google Play since January 2026.
