About

I am an indie developer and the maker behind Humpy Camel Studios, where I built Calmbox. After helping my wife navigate her mental health using CBT and DBT, I saw firsthand how frustrating it is when wellness apps lock basic support behind paywalls. My goal is to build practical, offline-first tools for nervous system regulation and mental health that are 100% free, ad-free, and accessible to anyone who needs help.
