The most advanced comic book reader for iPhone, iPad, and Apple Watch. CBR, CBZ, and PDF with on-device translation, read-aloud bubbles, guided panel reading, Right-to-Left manga, 3D depth, HDR, TV & Glasses Mode, and your whole cloud collection - in a stunning Liquid Glass library. TRANSLATE ANY COMIC, RIGHT ON THE PAGE Found a series that never got translated? Tap the globe. Lenticule reads the lettering and paints the translation back into the bubbles - same colors, same style, same energy. Not subtitles. The actual page, in your language. Translate a page or the whole issue in the background while you read, flip between original and translated instantly, and reword any line yourself. HEAR EVERY BUBBLE Tap a speech bubble to hear it read aloud - the original, the translation, or both - with a delivery that follows the mood of the scene. Turn on Natural Voices for lifelike narration. A great way to learn a language, one panel at a time. PRIVATE, OFFLINE, AND YOURS TO KEEP Text recognition, translation, voices, and an optional Apple Intelligence pass that keeps names and tone consistent all run on your device. Nothing is ever uploaded. Works in airplane mode, and exports as a fresh CBZ. The app speaks English, German, Spanish, French, Italian, and Macedonian. READ ON YOUR APPLE WATCH Send a comic from your iPhone and read it on your wrist, offline. Guided mode frames one panel at a time, the Digital Crown zooms in, and your place follows you back to the phone. Keep it in your Smart Stack or ask Siri to continue. GUIDED PANEL READING Lenticule maps every panel and guides you through the action one beat at a time - just the story, as the artist intended. TRUE RIGHT-TO-LEFT MANGA MODE RTL mode flips page order, navigation, and double-page spreads so gestures, panel guidance, and transitions all flow right. COLOR AND DYNAMIC RANGE True Hue for artist-accurate color, Noir for black-and-white contrast, and Accent to spotlight one color - set per comic. Extended Dynamic Range uses your screen's full brightness: vibrant inks, deep blacks, highlights that shine. YOUR CLOUD LIBRARY Connect Dropbox and OneDrive, or add any folder through the Files app - iCloud Drive, network shares, USB drives. Browse thousands of issues by cover and download only what you read. Run your own Komga, Kavita, or OPDS server? Add its address and your library arrives with covers, series, and metadata intact. Lenticule reads the server you host - it doesn't provide comics or help you find any. SCAN AND RESTORE Scan physical comics with your camera into clean CBZ files. Already have rough scans? Enhance crops the borders, straightens pages, and upscales the art with on-device AI - originals kept, so you can always undo. SPATIAL 3D, TV & GLASSES MODE The Spatial Engine gives flat art a parallax that makes characters feel alive. Plug in USB-C display glasses - XREAL, VITURE, RayNeo, Rokid - or AirPlay to your TV, and your phone becomes the remote. Side-by-side glasses get true stereoscopic depth. INTELLIGENT LIBRARY Every comic opens on an Overview of its cover, credits, and story. Pinch to resize covers from Showcase to Compact, and metadata organizes thousands of issues effortlessly. Huge PDFs scroll without lag, and any comic exports as the original or an optimized copy. DEVICE COMPATIBILITY Guided Panel Reading: 4 GB RAM+ (iPhone 11+; M-series iPads). Ultra-Detail: 6 GB RAM+. Natural Voices: 6 GB RAM+; one-time download. English, Spanish, French, Japanese, Chinese. HDR / EDR: Super Retina XDR or Liquid Retina XDR display. TV & Glasses Mode: any AirPlay screen or USB-C glasses; 3D needs side-by-side (SBS) glasses. Comic Translation: iOS 18 or later; language packs download once, then run offline. Apple Watch: watchOS 26 or later, paired with your iPhone. Watch reading is part of the full version. NOTE: Lenticule does NOT contain or distribute comics.
