I need a simple, reliable document-scanner that runs on both Android and iOS and ships to the Play Store and App Store without hiccups. The core task is straight-forward: open the camera, capture one or multiple pages, detect the edges automatically, crop, enhance, then save or share the result as a single PDF. Key functions I must see working smoothly: • Auto-cropping and page-boundary detection so users don’t have to fiddle with manual corners. • Local file management: folders, rename, quick search and the option to delete or re-order pages before final export. • One-tap “Save as PDF”. No OCR or deep editing—just clean scans. • Although “cloud storage integration” was ticked, I actually want files to stay on the device for now, so please implement local mobile storage with the architecture left open for future Google Drive / Dropbox / OneDrive hooks. Deliverables 1. Source code (Flutter, React Native, Kotlin/Swift, or another well-supported approach—your call, as long as review and future maintenance are easy). 2. Test builds for Android and iOS that demonstrate the full scan-to-PDF flow. 3. Final store-ready packages plus a brief setup document covering build steps, entitlements, and camera permissions. Acceptance criteria: the app launches, scans multi-page documents in less than 10 seconds per page on a mid-range phone, auto-detects edges accurately under normal indoor lighting, produces a single PDF under 300 dpi, stores it locally, and lets me move, rename, or delete it from an in-app library. If you have a ready-made framework or past project you can adapt quickly, even better—just make sure it meets the flow and UI polish needed for public release.

Hi, I can build this as a **lean Flutter document scanner** focused exactly on the scan → auto-crop → enhance → multi-page PDF → local library workflow, without unnecessary OCR or cloud features. I’d use Flutter with native camera/image-processing capabilities where needed to ensure reliable edge detection and fast processing on both Android and iOS. The app will include multi-page scanning, automatic boundaries, PDF export, local folders, search, rename, reorder and delete, with the storage layer structured for future Drive/Dropbox/OneDrive integration. I’ll provide test builds, complete source code, store-ready packages, and setup documentation covering permissions and deployment. I’ll also test against your acceptance criteria for scan speed, edge detection, PDF quality, and device compatibility. I can keep the first version focused and production-ready rather than overengineering it. Let’s discuss the UI flow and target devices so I can confirm the timeline and fixed scope. Regards Abhishek

Hi, I can build and ship your document scanner as a polished Flutter app for both Android and iOS. I have 4+ years of Flutter experience building production-ready mobile applications, including camera-based features, local storage, PDF generation, file management, and App Store/Play Store deployments. I’d use Flutter with a modular architecture, native camera/image-processing capabilities, and local storage designed so cloud providers like Google Drive, Dropbox, or OneDrive can be added later without restructuring the app. I’ll deliver: ✅ Automatic document edge detection & cropping ✅ Image enhancement for clean scans ✅ Multi-page scanning and page reordering ✅ One-tap PDF generation under 300 DPI ✅ Local folders, rename, search & delete ✅ Local-first storage architecture ✅ Android & iOS test builds ✅ Store-ready APK/AAB & iOS build ✅ Camera permissions, entitlements & setup documentation I’ll also optimize the scanning pipeline to meet your <10 seconds/page target on a mid-range device and thoroughly test the complete scan → edit → PDF → save/share workflow. I’m comfortable taking an existing scanning framework or building the required functionality cleanly from scratch, depending on what provides the best reliability. Best regards, Khushal

Hi there, I can build your cross-platform Document Scanner app for both iOS and Android efficiently using React Native. To ensure native-level performance, fast delivery, and high quality, I will integrate robust native scanning plugins (like react-native-document-scanner-plugin). This approach guarantees precise edge detection, auto-cropping, and perspective correction without reinventing the wheel or inflating your budget. Quick question: Do you need OCR (Text Recognition) built into the app, or just the ability to export and share the scanned documents as standard PDFs/JPEGs? Also, is there any specific cloud integration (like Google Drive/Dropbox) required? Let’s chat about the details and get this started.

I can build this as a clean Flutter document scanner for both Android and iOS, focusing on the part that matters most: fast and accurate automatic document detection. The scanning flow will be: Camera → Edge Detection → Auto Crop → Perspective Correction → Image Enhancement → Multi-Page Preview → Reorder/Delete → PDF Export → Local Storage → Share I’ll use a reliable document-scanning approach to detect the document boundaries automatically, correct the perspective, and produce clean scans without forcing users to manually adjust corners every time. The app will support: • Single & multi-page document scanning • Automatic edge/corner detection • Auto crop & perspective correction • Image enhancement for readable documents • Page preview, reorder and delete • One-tap PDF generation • Local document library • Folders, search, rename and delete • PDF sharing • No cloud dependency for now • Architecture ready for future Google Drive/Dropbox/OneDrive integration I’ll provide the complete Flutter source code, Android/iOS test builds, store-ready packages, camera permissions, iOS entitlements and setup documentation. I’ll also optimize the scanning and PDF generation flow to meet your target of under 10 seconds per page on a mid-range device. The goal is simple: point the camera at a document, capture it, and let the app handle the difficult work automatically.

Hello, We reviewed your brief - a clean, reliable document scanner for Android and iOS: camera capture of single/multiple pages, automatic edge detection and crop, enhancement, one-tap Save as PDF, and a local library with folders, rename, search, reorder and delete - files kept on-device now, with the architecture left open for Google Drive/Dropbox/OneDrive later. We build camera and document-processing apps in Flutter/React Native with accurate edge detection and clean PDF export, ready for both stores. Team of 20. One question: any target minimum iOS/Android versions, and should scans support colour, grayscale and black-and-white enhancement modes? - APIE Technologies

Hi, Your scanner app has a focused MVP, and the key is making the scan-to-PDF flow fast and effortless. I can build it as a cross-platform app while keeping document processing local and leaving a clean integration layer for future cloud storage. I’d recommend Flutter for Android/iOS, with native camera/document-detection capabilities where required and local storage for documents. This gives you one maintainable codebase while allowing platform-specific optimization for camera performance and permissions. My approach will include: * Camera capture with automatic edge/page-boundary detection * Auto-cropping and image enhancement * Multi-page scanning and page reordering * Local folders, rename, search and delete * One-tap PDF generation under the required resolution * Local-first document storage with future cloud hooks * Smooth UI optimized for quick scanning * Camera/storage permissions handled correctly * Android and iOS testing on representative devices * Store-ready APK/AAB and iOS build preparation * Setup, build and entitlement documentation I’d be happy to discuss your vision and suggest ideas to make Fabulous Garments stand out online. Looking forward to working with you! Best Regards, Prachi Webix Infotech

Auto edge detection is the whole product. Everything else in a scanner app is plumbing — if the crop is unreliable, users go back to their phone's built-in scanner within a week. So that is where the effort belongs: - Edge detection using a proven computer-vision pipeline rather than a hand-rolled one, with a manual corner-adjust fallback for the cases it gets wrong. It will get some wrong; hiding that is worse than handling it. - Enhancement modes that actually help — a contrast-boosted black-and-white for text, colour preserved for anything else. - Multi-page capture into one PDF, with reorder and delete before saving. - Local file management: folders, rename, search, share. All on-device, no account needed, which is also what keeps store review simple. - Built cross-platform from one codebase so Android and iOS stay in sync, then submitted to both stores. Proof: cross-platform apps in production on iOS, Android and web from one codebase, already through both store review processes — plus document-processing and PDF generation pipelines running in production, which is the other half of this app. Questions: do you want OCR text search inside saved documents? It is a common follow-up request and cheaper to plan for now than to retrofit. And should files stay purely local, or is cloud sync expected later? Martin

Hello, Creating a seamless document-scanner for Android and iOS involves prioritizing user experience over complex features. The main focus should be on intuitive auto-cropping and page-boundary detection to streamline the scanning process. Implementing efficient local file management with options for organization and customization will enhance user satisfaction. The one-tap "Save as PDF" feature should be straightforward, ensuring clean scans without unnecessary complexities. While cloud storage integration is a future consideration, the initial emphasis will be on local mobile storage to maintain simplicity. To achieve this, I would begin by reviewing the existing architecture and selecting a well-supported approach like Flutter or React Native for easy maintenance. I have experience in developing similar mobile scanning applications that prioritize efficiency and user-friendly functionalities. A few questions: - Have you considered any specific design preferences for the app's UI/UX? - Are there any specific performance benchmarks you would like to meet for the scanning process? Best regards,
