I build small apps on my own, from the first sketch to the store page.

See the apps or say hi

On the shelf.

Bro brings back a sample, I bottle it. Four so far.

Meet the element.

I'm febroine, and I make apps. Mostly for phones, sometimes for servers.

I design them, write the code, run the servers and fill in the store forms myself. Every app gets a page here, and the support address goes straight to me.

Most of what I build keeps your data on your phone. When something has to go to a server, the app's privacy page says what goes, and for how long.

The astronaut over the pool is Bro. He's out collecting samples of element 119, and he doesn't mind being poked.

Pick a reagent and an app, and the email starts with a template.

I read everything. Code lives on GitHub.
