Perfect OCR gives you both a general purpose OCR app and a document scanner. Now you can scan and OCR your letter-size or A4 documents with an accuracy of 90% or more, edit, copy and store the recognized text, and e-mail your documents as PDF files with text, SINGLE page image, or both together! NOTE: To ensure the advertised results it is important that you follow the OCR TIPS below (or in the app's help). Perfect OCR scans your documents using advanced image-processing algorithms to eliminate uneven lighting and shadows and improve contrast. The result is the clearest and most readable scans possible from the iPhone's camera. Perfect OCR also offers SureScan, our proprietary scanning mode that delivers sharper images with less jitter or smear. Our unique "Email to myself" feature lets you send documents to a predefined address, or even upload them to an online storage service like Evernote or Box.net, with a single tap. Uploading documents to online services via email is fast, secure, and can be done even if you're temporarily off line. Refer to app help for details. All processing happens on your iPhone, and the confidentiality of your data is never compromised. There is also no subscription fee, and no Internet access is needed to scan documents or run OCR. PERFECT OCR FEATURES: • Letter-size or A4 page OCR with accuracy of 95% for model 3GS, 98% for iPhone 4, and up to 90% for 3G • OCR languages: English, French, Spanish, German, Dutch, Italian, Portuguese, Swedish, Russian, Polish, Hungarian, Czech and Ukrainian. • Email multipage PDFs with text, SINGLE page image, or both • Automatic document edge detection and perspective correction • Multipage text recognition with accuracy indicator • Text editing and copy-to-clipboard operations • Built-in OCR text archive with file sharing via iTunes • "Email to myself" feature • Email text and image files (.TXT + .JPG), or save image to library • Searchable PDFs with document images (single page) • Preserves simple text formatting • Option to auto-remove line breaks • SureScan mode for jitter-free scans • Simple yet powerful user interface • Instant brightness, rotation, and color controls • Compact attachments with adjustable size IMPORTANT TIPS FOR OCR: • Make sure your document is flat and well lit. Hold your iPhone still while shooting. • Always scan documents using "SureScan 3x" mode. • Glossy paper may not work well (avoid glare). • When scanning books keep the pages as flat as possible and your iPhone parallel to the surface. • Perfect OCR cannot recognize handwritten, very large text or spreadsheets correctly. • Make sure to select the right language for OCR in app settings.

Verdict
The clearest difference is price: Proton Drive at Free against Perfect OCR's $0.99. Proton Drive also leads on update cadence (fortnightly vs every 2 months) and ratings volume (1.2K vs 118). Perfect OCR's advantage is rating (4.7 vs 4.1) and in-app purchases (none vs 9). On ads, device support and iOS requirement there is nothing between them.
