Raketten Cropper vs iScan

The cropper tool from Raketten is a very small tool which solves a big problem. Whenever you take a photo of some rectangular shape, like a box or a book. TRaditional cropping will not give you a good result due to the perspective error. Either you have to accept some air around the box, or you have to accept loosing part of your box. This is where Raketten cropper can help you. It lets you select each of the 4 corners and warp your box to show only the box. The tool does not require an account or any personal information, just install and use.

iScan-D is a document scanner for anything from receipts and contracts to posters — no fixed page size. Capture, de-skew, OCR, search, and export all happen on your device. There's no sign-in, and your images and recognized text are never sent to a server. ■ Two scan modes • Normal scan: capture receipts, business cards, postcards, and everyday documents one sheet at a time. • Long scan: move the camera slowly downward to stitch a very long receipt into a single tall image. ■ Import from your photo library Already have a photo? Select one or several and bring them in as pages — no need to reshoot. ■ Precise cropping and de-skewing • The document's four corners are detected automatically. Fine-tune them by hand, with a magnifier so your finger never hides the corner. • A perspective transform straightens the page so a photo taken at an angle looks like it was shot head-on. • Corner cropping and a final rectangular crop are separate steps. ■ Finishing touches • Rotate, rectangular crop, brightness, contrast, saturation, sharpness, grayscale. • One-tap "Enhance" removes shadows and uneven lighting, whitens the background, and makes text crisp. • Brightness, contrast, and saturation preview in real time and can each be reset individually. ■ OCR in 9 languages Japanese, English, Italian, Spanish, French, German, Korean, and Chinese (Simplified / Traditional). OCR runs on device using Apple's technology, and the language follows your app language automatically. Recognized text is fully editable, and pages that fail recognition can be typed in by hand. ■ Find it, share it • Full-text search across titles, notes, and OCR text, with a snippet of the matching text. • PDF export embeds an invisible text layer so you can search inside the exported PDF. • Export as PDF, JPEG, or PNG, with paper sizes (A4, A5, B5, Letter, custom) and image sizes (original, large, medium, small, custom). • Combine multiple pages into one PDF in order and share it. ■ Organize and manage • Give each document a title and a note; the title is generated from the capture date. • The original image is always kept, so you can redo corner adjustment, perspective, editing, and OCR even after saving. • Deleted documents go to Trash. They can be restored for 10 days, then are permanently deleted automatically. You can also delete permanently right away. ■ Privacy • Images, OCR results, and document information are never sent off device. • All key processing, including OCR, works on device and offline. • No account or sign-in. • No cloud sync or built-in backup. ■ Requirements Supports the latest iOS and the two previous major versions.
