About
Codex is an audiobook player that looks different, feels different, and works different. Not a generic app — a device.
Inspired by the design philosophy of Dieter Rams, Codex combines precise haptics with minimalist aesthetics. Every element has a function. No element is decoration.
YOUR PLAYER, YOUR DESIGN
The centerpiece of Codex is the Jog Wheel — rotate it to scrub, tap to navigate. Add physical toggle switches, faders, and an interface that feels like a real device.

What's New in Codex
1.0.1
June 9, 2026
• Audiobook lengths are now shown accurately – totals and chapters are correct. • Chapters end where they should – no more playing past the end of a chapter. • Precise duration detection for MP3, M4A/M4B, FLAC, and Ogg/Opus files. • Cassette deck: the chapter buttons no longer interrupt playback. • Finished audiobooks automatically move to "Listened". • "Mark as unlistened" now also works for the currently loaded audiobook. • Minor stability and detail improvements. Tip: Re-import previously imported audiobooks once to pick up the corrected lengths and chapters.
