A full course library in your pocket.

Phone University is a mobile learning app that lets you download and consume educational courses on your iPhone or iPad.

How courses work

Courses are stored as zip files on a Cloudflare R2 bucket and contain markdown text files for reading and MP3 audio files for listening. When you download a course, the app extracts it, parses the markdown into chapters and sections, and presents the content in a clean, readable format with chapter navigation.

Audio player built for learning

The app features a full-featured audio player for listening to course content, complete with playback speed control (0.5x to 3x), skip forward/back, chapter navigation, and background audio support with Lock Screen controls.

Your listening position is automatically saved when you pause, and playback resumes after interruptions like phone calls or text messages.

Course visuals

Each course can have a cover image or per-chapter images that display during reading and audio playback.
