Bloox - an on-device-AI audiobook player

Bloox is an on-device AI audiobook player for iOS that adds transcription, character tracking, and spoiler-aware question answering to help listeners follow complex narratives. It is built for avid audiobook listeners who lose focus during long or intricate books and want a way to catch up without rewinding blindly. The app shows live, word-level transcription synced to the audio, tracks the cast of characters with descriptions and name highlighting, and lets users ask Book Chat questions about what they have heard so far. A "What Did I Miss?" feature generates AI catch-up summaries for moments when attention drifts, and a smart rewind automatically backs up after calls or pauses. Bloox plays personal audiobook libraries imported from Audible, Audiobookshelf, Google Drive, iCloud, or Wi-Fi upload, and supports M4B, MP3, and CUE chapter markers. Listening features include 0.5x to 2.0x playback speeds, a sleep timer with a gentle chime, smart bookmarks with transcript context, a home-screen resume widget, listening insights, and Siri and Shortcuts integration. Because the AI runs on-device, processing stays local to the phone. Bloox is completely free with no subscriptions, in-app purchases, or ads, and no account is required to play personal files.
