Doc Scanner: Offline PDF OCR

Scanning with OCR and Translation in One Flow

The camera opens to a live preview with a floating capture button. Point it at a document, and the app draws a white outline around the edges. It detects the page automatically. Tap the button, and the app captures the image, straightens the perspective, and applies a default enhancement filter. The result appears on the next screen. You can adjust the crop, change the filter, or add more pages. Each page stacks into a multi-page document. When you finish, you tap the export button. The app processes the images, runs OCR on each page, and generates a PDF with an embedded text layer. The text layer makes the PDF searchable in any PDF reader. You can also export the recognized text as a Word document or plain text file. The entire process happens on your device. No data leaves your phone. The workflow from capture to export takes under a minute for a single page.

The translation feature sits inside the OCR results screen. After the app recognizes text, a translate button appears. Tap it, and the app uses on-device translation models to convert the text into one of over 50 languages. The translation happens without an internet connection. This is useful for travelers, students, or anyone dealing with foreign-language documents. The translated text can be copied, shared, or exported alongside the original. The combination of offline OCR and offline translation is rare in free scanning apps. Most competitors require cloud processing for translation. This app does everything locally. The trade-off is that translation accuracy depends on the OCR accuracy. If the OCR misreads a word, the translation will be wrong. The app does not warn you about this dependency.

How It Stacks Up Against Adobe Scan

Adobe Scan is the market leader in mobile document scanning. It offers similar features: edge detection, OCR, PDF creation, and cloud storage. The key difference is the cloud dependency. Adobe Scan requires an internet connection for OCR and most advanced features. It uploads your documents to Adobe's servers for processing. This app does everything offline. Your documents never leave your device. For privacy-conscious users, this is a significant advantage. Adobe Scan also pushes its subscription model. The free version is limited, and many features require a Creative Cloud subscription. This app is completely free, with a one-time Pro unlock for extras like removing the export footer. Adobe Scan has better OCR accuracy for complex layouts and handwritten text. It also has more polished UI and better integration with other Adobe products. However, for users who value privacy, offline operation, and zero recurring costs, this app is a strong alternative. The trade-off is occasional bugs and less polished performance, as noted in user reviews.

What the Updates Actually Changed

The developer has not published a detailed changelog for this app. The Play Store listing shows no "What's New" section. Third-party sites like AppBrain show an empty changelog section. This tells you nothing specific. No mention of which bugs were fixed, whether performance improved, or if any features were added. The current version is 1.6.0, but without a changelog, it is impossible to know what distinguishes it from previous versions. This lack of transparency is common among smaller developers, but it leaves users guessing. If a bug that annoyed you in an earlier version has been fixed, you would not know until you installed the update and tested it yourself. The developer has not provided any official communication about the update cycle, so the version number is essentially a black box. Users have reported issues like app crashes, inconsistent file conversion, and lack of auto-cropping. None of these are mentioned in any changelog. Users are left to discover whether an update helps by trial and error.

When the Pro Unlock Becomes the Only Option

The free version of the app includes a small footer on exported PDFs. The footer says "Made with Doc Scanner" or similar text. It is not intrusive, but it is present on every page. The Pro unlock removes this footer and adds extra features like batch scanning and additional export formats. The Pro unlock is a one-time purchase, not a subscription. This is a fair model. However, the free version also includes ads. The ads appear during the scanning workflow, which can be disruptive. Some users have reported that the ads are intrusive enough to hinder basic functionality. The Pro unlock removes the ads as well. For users who scan documents frequently, the Pro unlock becomes necessary for a smooth experience. The app does not clearly communicate the ad frequency or the footer placement before download. This lack of transparency can be frustrating. The app is free to download, but the full experience requires a purchase. The pricing is not disclosed on the Play Store page, so users must install the app to see the Pro upgrade options.
