Everyday apps for everyday life.
Three Brain Apps is a founder-owned software studio. We build small, focused apps for iPhone and Mac. Each one does a single thing well, then stays out of your way. Every project starts with a problem we ran into ourselves and couldn't solve with what already existed.
No feature bloat, no accounts you don't need, no dark patterns. If it needs a manual, we designed it wrong.
We release when it's ready rather than when the calendar says so, and we keep maintaining what we release.
The best tools quietly take work off your hands and fit into the rhythm of your day. Ours are built to be useful first and invisible after: you feel the result, not the app.
An outfit visualizer. Photograph a piece you own, or one you're considering, then pair it with a second piece and see the two styled together as a single Look before you buy it or wear it out. Built for the moment in the fitting room when you're trying to remember what's hanging in your closet at home. Launching 2026.
A menu-bar utility for anyone running an RME audio interface. It maps the Mac's volume keys to the master fader in TotalMix FX over OSC, so F10, F11 and F12 control the hardware the way they always should have. Works with the Fireface, Babyface, MADIface and Digiface families.
A native Mac app for running an Android TV box (Xiaomi Mi Box, Google TV, and the rest) over wireless ADB. Manage apps and settings from your keyboard instead of pecking through a television menu with a remote.
A trend-watch tool for the mobile app market. It surfaces recently released apps that are already climbing the charts, so you can catch what's breaking out early.
A learning app. We're validating the ideas behind it with a language bot first, and the app follows once they hold up.
