SixTwelve Studio · Native apps for the Mac

Curated Shelf · 20 Instruments

Native apps for the Mac

For the hours you spend at the desk. Verso and roono are places to write. Linen Editor is the zero-prompt workbench for raw text and code. Folio puts unruly PDFs in order. Lumen and CaptureMood are darkrooms for your photographs. Mocksyy is a sketchbook for people who design apps. Each is made to feel at home on the Mac, and to stay out of your way.

Why this shelf Philosophy & Standards
01 The Intention

One tool, one craft, zero noise.

Every instrument in this collection is designed for a single dedicated practice. We do not bury simple tasks under complex settings, bloated feature sets, or algorithmic recommendations.

02 The Independence

Local files and perpetual ownership.

You buy these tools once. They live directly on your device, work completely offline, and keep all your photographs, writing, and documents strictly in your own custody.

The Bench, a weekly letter

Every Tuesday, a short letter from the studio: one app worth a closer look, one small idea for using it well, and a glimpse of what is being made next.
