Build a narrowly scoped Android podcast player with subscription import, a clearly labeled library, downloads, sleep controls, and heavily tested background and casting playback. Sell it through a one-time purchase or modest subscription, with an optional supporter tier, and avoid advertising or promoted content.

The signals show both dissatisfaction with ad-supported players and willingness to support a focused alternative. Recent playback regressions also demonstrate that reliability itself can be a differentiator, although mature free competitors make customer acquisition difficult.
