Unlike single-purpose PDF readers, TTS apps, or media players, Nexo Player brings reading, listening, playback, export, and private storage into one Android app. Turn PDFs, EPUBs, and pasted text into narrated audiobooks, continue from saved progress, and export as M4B, MP3, WAV, or ZIP. It also plays local video and music and includes a PIN/biometric vault. Narration is offline-first, so your documents and generated audio stay on your device.
