Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Castbox

  • App frequently crashes, requiring users to reload it to continue listening
  • Approximately half of saved podcasts do not automatically refresh or send notifications for new episodes
  • Free version displays unskippable minute-long ads that sometimes play as blank screens
  • Interface is described as cluttered with excessive focus on mainstream podcast recommendations
  • Tracking requirements for certain features like background playback limit privacy

IINA

  • There is no Apple TV or iOS app, so it cannot be used for a living room streaming setup the way Infuse can.
  • It has no polished network share or cloud storage library browser, so streaming from a NAS or cloud drive is more manual than with Infuse.
  • As a volunteer open source project, new feature development and bug fixes depend on contributor availability rather than a funded team.
  • It is Mac only, so there is no equivalent app for Windows users in a mixed household.
  • Advanced mpv configuration is still exposed for power users, which can be confusing for someone who just wants simple playback with no options.
