About

We make the world simpler.

Runesmith Studio is an independent app studio in Shanghai. We believe technology should make life simpler, not busier — so we build a small, carefully made collection of iOS apps, each designed to do one useful thing, work offline, and respect the person using it.

Story

Small software, clear purpose.

Your data is yours. No ads, no tracking that follows you, no selling.

Values

How we decide what belongs.

Simple by design

Every app does one thing, and does it well. No clutter, no bloat.

Your data is yours

No ads, no data brokers, no cross-app tracking. Many of our apps work fully offline.

Fewer, better

We'd rather make a few apps we're proud of than many we forget.

AI-built, human-finished

We use AI to move fast, and human craft to get it right.
