See how it works— About Ethelium
Ethelium Apps is the one-person iOS studio of Ethan Brown. I build apps for things I personally do — boxing, hosting, and whatever comes next — because the existing apps for those things were almost always over-subscribed, over-designed, or over-engineered.
Every Ethelium app ships free, runs entirely on-device when possible, and never sells your data. If something's broken or missing, tell me — I read every email.
