DotPen Companion: Cross-platform client for reading pens

Manage reading pen content on Mac without a virtual machine

Problem: The official client for Xiaodaren reading pens is Windows-only, forcing Mac users to install a 30GB virtual machine just to manage audio packages. This wastes storage and adds friction. One user even built their own Mac tool to solve this.
Solution: A native Mac app that installs DAB/UNB audio packages, manages installed content, and edits book labels—no VM required, plug and play.
Users: Parents using reading pens, especially Mac users
MVP: Read pen file system; install DAB packages; list installed content; export/import data; simple UI.
Revenue: One-time purchase $5–$10; or freemium with advanced features paid.
Why now: Growing demand for home education and reading pens, but official software lags; indie developers can fill the gap.
