Read full descriptionHide full description
DualText Scanner is a book scanner app for iPhone and iPad that lets you capture, enhance, read, search, and organize paper books and PDFs. Photograph book pages one by one and save them as easy-to-read digital data. Captured pages can be enhanced with distortion correction, shadow removal, whitening, contrast adjustment, and text enhancement. β Free Version and Pro Version This app is free to download. The free version lets you save up to two books and try scanning, image correction, OCR, and the built-in viewer. By upgrading to the Pro version through an in-app purchase, the book limit is removed. As long as your device has enough storage space, you can manage paper books and PDFs as your own searchable digital bookshelf. The Pro version is a one-time purchase upgrade, not a subscription. β Manage Scans by Book Scanned pages are managed by book. If you stop scanning partway through, you can check the next page number and resume later. You can gradually add pages and build your digital bookshelf over time. β Easy Capture and Page Correction When taking photos, the app displays a document detection overlay to help you check the page area. After capturing a page, you can manually adjust the four corners to correct open books or slightly curved pages. Perspective correction, shadow removal, whitening, and text enhancement help turn paper pages into clean, readable images. β Vertical and Horizontal OCR DualText Scanner supports OCR for both vertical and horizontal Japanese text. You can extract text from novels, practical books, reference materials, textbooks, and other book pages. You can also exclude top, bottom, left, and right areas from OCR. This helps avoid page numbers, chapter titles, margins, or repeated text, making it easier to focus on the main text. Extracted text can be edited while viewing the page image. On iPad or in landscape orientation, the image and text editor can be displayed side by side. β Export Searchable PDFs Captured pages can be exported as PDF files. By embedding OCR text into the PDF, you can create searchable PDFs for computers. β Export Text as CSV or Plain Text OCR text can be reviewed by book and exported as CSV or plain text. This is useful for study, research, note organization, checking text before quoting, and working with other apps. β E-Book Style Viewer Saved pages can be read in the built-in viewer. You can choose horizontal or vertical page turning, depending on the book and your preferred reading style. The viewer includes keyword search and search history, allowing you to quickly move to pages that contain the words you are looking for. β Clip Feature You can save favorite passages or sections as clips. Each clip can include the book title, author, page number, and text. Clips can be viewed across books and are useful for reading notes, study notes, and organizing references. Saved clips can also be copied or exported as CSV. β PDF Import You can import existing PDFs, convert each page into an image, and register them as book data. Imported PDFs can also be used with image correction, OCR, text editing, and viewer reading. β Backup and Restore You can back up book images, extracted text, clips, settings, and other data together. The backup destination can be selected by the user, such as iCloud Drive or the Files app. By restoring a backup file on another device, you can recreate the same book environment. β Privacy DualText Scanner does not send book images or extracted text to our company servers. Main processing such as image correction and OCR is performed on the device. When sharing PDFs, CSV files, extracted text, or other data with external apps or cloud services, please check the terms and privacy policy of the destination service and manage the data at your own discretion. DualText Scanner helps you create book data that you can read, search, and use later. Organize your important books as your own searchable digital bookshelf.

Transcribe turns speech into text, and text into another language β entirely on your iPhone or iPad. Record a meeting, a lecture or a voice memo and get a transcript. Import an audio file instead. Translate the transcript, read the translation beside the original, have a summary written for you, or ask the recording questions. NOTHING LEAVES YOUR DEVICE β’ No account, no sign-in, no subscription β’ No servers of ours: your audio and your text are never uploaded β’ Transcription needs no network at all, so it works offline and in airplane mode β’ The app collects no data β that is the whole privacy policy TRANSCRIPTION, ON DEVICE β’ Runs on the Neural Engine with Parakeet, built into the app β 25 European languages, no download β’ Need more languages? Download the optional Whisper large-v3-turbo model once for 99 languages β’ Live preview while you record, then a full-quality pass over the finished audio β’ Also transcribes audio files you import from Files or share from another app β’ Fix anything it mishears: the transcript is yours to edit TRANSLATION β’ Translate a transcript into the language you choose β’ Translation runs on device, and by default uses Apple's built-in translation β so there is nothing to download before your first translation β’ If the system is missing a language pack, the app says which one and where to get it β’ Prefer no limits on language? Download the optional on-device model once and every language the recogniser can hear becomes a translation target, direct between any two SUMMARY AND QUESTIONS β’ Ask the on-device model for a summary of a long recording: a few sentences, saved with the transcript β’ Ask questions about a recording and get answers drawn from what was actually said, in a conversation you can keep β’ Both are written in any language you pick β’ Both use the optional on-device model, which is installed once from Settings β’ Bring your own model instead: import any .gguf file you already have, and translation, summaries and questions all use it WHAT TO EXPECT β’ Apple's built-in translation covers the languages the system supports; the optional model covers all 99 the recogniser can hear β’ The optional on-device model is about 1.22 GB, downloaded once over Wi-Fi, and after that works offline permanently β’ The app is about 610 MB, and about 1.8 GB with the optional model installed β’ Automatic transcription, translation, summaries and answers are good but not perfect. They can mishear names, numbers and technical terms, particularly with background noise, strong accents or several people talking at once. Please check anything that matters β’ Transcribe is not a substitute for a professional interpreter or translator REQUIREMENTS β’ iOS 18.0 or later ATTRIBUTION Speech recognition uses Parakeet (CC BY 4.0 licence, Β© NVIDIA and moondream) or OpenAI's Whisper (MIT licence, Β© OpenAI). Summaries and questions use Qwen3 (Apache License 2.0, Β© Alibaba Qwen team). Everything runs locally on your device; no model is modified.

Verdict
The clearest difference is price: DualTextScanner at Free against Voice to Text Offline's $2.99. DualTextScanner also leads on iOS requirement (16.0 vs 18.0). Voice to Text Offline's advantage is in-app purchases (none vs 1) and update cadence (every 5 days vs every 2 months). On ads and device support there is nothing between them.
