Morph is the reading app that shapes itself to you. Read, listen, or do both — it adapts to however you want to experience your books. READ WITH FOCUS Import any EPUB and read in a clean, distraction-free reader. Customize your font, theme, and spacing. Highlight passages with smooth, marker-style highlights and save quotes as you go. LISTEN WITH NATURAL AI VOICES Turn any book into an audiobook with AI-powered text-to-speech. Follow along with word-level highlighting that keeps you in sync. Play in the background while you cook, commute, or work out. READ AND LISTEN AT THE SAME TIME Studies show you retain significantly more when you read and listen simultaneously. Morph makes it effortless — just tap play and follow along. Focus mode highlights the current word as it's spoken, so your eyes follow naturally without strain. Less effort, more retention. RSVP (Rapid Serial Visual Presentation) The First RSVP paired with audio to allow you to not only read faster, but have better comprehension, memory and focus! BROWSE THE MORPH STORE Explore hundreds of public domain classics — from Austen to Dostoevsky — curated into collections and ready to download with one tap. Search by title or author, browse by genre, and build your library without leaving the app. New users get a free book to start reading immediately. ASK YOUR BOOKS QUESTIONS Stuck on a concept? Curious about a character? The AI assistant reads along with you and answers any questions about what you're reading, right from the page. TRACK YOUR READING LIFE Set daily goals, build streaks, and see your reading stats over time. Watch your habits transform. YOUR LIBRARY, EVERYWHERE Sync your books, highlights, and progress across all your devices. Pick up exactly where you left off. BUILT FOR READERS, NOT JUST LISTENERS Most TTS apps treat reading as an afterthought — they strip the book down to an audio feed and call it done. Morph was built the other way around. Reading comes first. The text is always beautiful, always yours. TTS is there when you want it, gone when you don't. Switch between reading, listening, or both with a single tap. No mode feels like a compromise. WORKS 100% OFFLINE Morph runs a local AI voice model directly on your device. No internet needed, no streaming delays, no buffering. Import a book, close your wifi, and listen. It just works. MORPH EXCLUSIVE VOICES Custom-built voices you won't find anywhere else. Warm, natural, and designed specifically for long-form reading. Choose from multiple voices or switch to whisper mode — soft, slowed ASMR-style narration perfect for winding down before sleep. IMPORT ANYTHING EPUBs from your device, articles from the web, PDFs — if you can read it, you can Morph it. Import by file, URL, or share sheet. DESIGNED FOR YOUR LIFE Set a sleep timer and drift off to a book. Listen in the background while you drive, cook, or work out. Seamlessly switch between reading and listening without losing your place. Morph fits around your day, not the other way around.

Listen to Safari articles and imported documents entirely on-device — no internet required for playback. NaturalLocalReader offers English and Chinese text-to-speech with voice cloning, optional AI-powered multi-voice narration, a Safari extension, offline audio preparation, and a saved reading library. Use the Safari extension to send any article straight into the app, or import `.txt`, `.epub`, `.pdf`, `.md`, or `.html` files and keep them in a reading library with saved progress. Pick up where you left off, jump to any paragraph or chapter, and listen with simple playback controls. **English and Chinese playback, fully on-device.** English content is read using PocketTTS — a fast, natural-sounding engine with voice cloning support. Chinese content uses MOSS — a CoreML-powered voice engine also with voice cloning. Record a short clip or import any audio file, and the engine reads in your voice. No internet connection needed for any engine. **Voice cloning for English and Chinese.** Record a short clip in Settings → Voice Reference and the engine reads in your voice — available for both PocketTTS (English) and MOSS (Chinese). MOSS also lets you save multiple named voice references and switch between them instantly. **Multi-voice narration, for an audiobook feel.** Turn this on in Settings with your own free Gemini API key, and imported Chinese or English books are automatically read with a distinct voice per character — narrator, dialogue, and each speaker read separately. It's entirely opt-in and off by default; the resulting audio is still prepared and played back on-device. For longer listening sessions, NaturalLocalReader can prepare offline audio for any saved file so you can keep listening with fewer pauses. Preparation is resumable — start, stop, and pick up again any time. NaturalLocalReader requires a subscription or one-time purchase to access all features. A 7-day free trial is included with the subscription. ### Highlights - Send article text from Safari to the iOS app with one tap. - Import and save `.txt`, `.epub`, `.pdf`, `.md`, and `.html` files in an in-app reading library. - Read English text aloud using PocketTTS with voice cloning — record your voice and PocketTTS reads in your style. - Read Chinese text aloud using MOSS with voice cloning — record your voice and MOSS reads in your style. - Save multiple named voice references for Chinese and switch between them in Settings. - Jump to any paragraph by tapping it; navigate chapters with the chapter list. - Return to the home screen without losing the current article or saved text. - Keep your reading progress for any reopened saved file. - Prepare offline audio for any imported file and resume unfinished preparation later. - Adjust playback speed: 0.75×, 1×, 1.25×, 1.5×, or 2×. - Use on-device playback — your content stays private, nothing leaves your device. ### Current playback experience - **English** uses PocketTTS (on-device, voice cloning supported). - **Chinese** uses MOSS (on-device CoreML, voice cloning supported) or Qwen (on-device, no internet required). ### Good fit for - People with dyslexia, ADHD, or reading fatigue who prefer listening - Reading articles while walking, commuting, or doing chores - Listening to Chinese web novels, articles, or study material on the go - Reducing screen fatigue - Saving long documents to listen later - Listening to imported ebooks (EPUB, PDF) with saved progress Terms of Use: This app uses Apple’s standard End User License Agreement (EULA). https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict

The call

ReceptionRating · Positive reviews · Number of ratings

NaturalLocalReader holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: Morph Books has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 75% of Morph Books's written reviews are positive against 0% of NaturalLocalReader's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 days. Both last shipped on October 31, 2026.
