fxjima

An independent app studio

The special-effects island.

fxjima is a one-person studio making small, obsessive apps for iPhone, iPad, and Mac. The intelligence runs on your device — the island — and nothing leaves the shore.

The name

Why an island?

fx, as in special effects. jima (島), as in the Japanese word for island. Put together: a small island where effects are made — sound synthesized out of thin air, tone read between the lines, flashcards that write themselves.

The island is also how everything here is built. Modern apps ship your words, your habits, and your voice to someone else's computer. fxjima apps run Apple's on-device intelligence instead: the models live on your iPhone, the thinking happens there, and your data never leaves the shore.

One person. Native code. No ads, no trackers, no accounts. Apps ship when they feel right — not when a quarter ends.

fxjima — say it fx·jee·ma. Always lowercase.

How we build

Three rules of the island.

Native to the core

Swift, SwiftUI, and the platform's own frameworks — down to the audio render callback. Apps that feel like they came with the device.

Nothing leaves the shore

On-device intelligence by default. No analytics, no third-party SDKs, no data collection. Privacy isn't a setting; it's the architecture.

Feel over features

Haptics tuned by hand, motion at 120 Hz, sound at the speed of touch. If a detail can be felt, it gets obsessed over.
