QRCode ScanStudio: PDF Lab is not a one-button QR reader. It is a structured code workspace for capturing, decoding, generating, exporting, and organizing machine-readable content on iPhone. The app combines a live camera scanning pipeline, still-image code extraction, semantic payload parsing, QR and barcode generation, document-to-PDF export, and a searchable local library in one native workflow. The result is a tool that behaves more like a compact content instrument than a disposable scanner utility. Live scanning is built on a real-time camera session with continuous autofocus, smooth focus behavior, center-weighted focus and exposure tuning, subject-area monitoring, torch control, and duplicate suppression logic. This helps the scanner remain stable during repeated reads and reduces accidental re-capture of the same payload. It also works beyond the camera. You can import an image from Photos and run barcode or QR detection on the still image, which is useful when codes are embedded in screenshots, posters, invoices, packaging, or archived media. Instead of treating every scan as raw text, the app classifies and interprets supported payloads into structured result types, including: URLs Email addresses Phone numbers SMS payloads Wi-Fi credentials vCard contact data Calendar event payloads Location-style payloads Plain text and generic barcode content When a payload contains structured data, decomposed fields are presented for faster review. For example, Wi-Fi content can expose network name, security type, and password fields; contact payloads can separate name, company, phone, and email; event payloads can surface title, location, start time, and end time. The built-in creation studio can generate scannable QR codes or barcodes for multiple real-world scenarios, including websites, text, Wi-Fi access, email, phone, SMS, contact cards, events, addresses, app links, crypto addresses, and selected social/profile shortcuts. Generated codes can be previewed, shared, stored, favorited, and revisited from the in-app library. For document workflows, PDF creation is available in two practical forms: Build one PDF from selected photos Capture paper pages with the document scanner and export them as a PDF file Everything is organized in a local history system with search, filters, favorites, generated-code records, scanned-result records, and PDF document records. Additional controls include optional scan history saving, haptic feedback, scan sound, detected-code highlighting, and automatic opening of scanned links when enabled by the user. Subscription & In-App Purchase Information Some features require a subscription. Payment will be charged to your Apple ID at confirmation of purchase.

About

ScanFlow PDF Scanner

Features
Read full description

ScanFlow PDF Scanner is a PDF workstation for scanning, converting, editing, protecting, and understanding documents in one structured workflow. It is designed for users who need more than a single-purpose scanner, allowing files to move from capture to OCR, conversion, page editing, privacy handling, AI processing, and export without switching between disconnected tools. The app is organized into dedicated workspaces for Scan, Convert, Library, AI, and Private. Scanning is only one entry point: documents can be recognized, converted, annotated, signed, reorganized, protected, summarized, and exported through a more complete document workflow. In the Scan workspace, the app supports camera capture, photo import, document scanning, and OCR-based text recognition. Its imaging flow helps improve real-world captures through document boundary detection, perspective correction, orientation adjustment, shadow reduction, contrast refinement, grayscale or black-and-white enhancement, and OCR-focused readability processing. The Convert workspace works as a practical hub for mixed document sources. It supports image to PDF, PDF to image, Word to PDF, Excel to PDF, PPT to PDF, web page to PDF, PDF merge, PDF split, page reordering, compression, and OCR text extraction. Preview and page-level controls help users check results before export. The PDF editing environment supports document viewing, page previews, highlights, underline, strikeout, squiggly markup, notes, text overlays, signatures, page rotation, blank page insertion, page deletion, and saving refined copies with clearer control over document state. The Private workspace is designed for confidentiality-oriented tasks. It supports sensitive-field detection, redaction workflows, password protection, privacy watermark generation, and local signature handling. For supported content, the app can analyze recognized text patterns such as email addresses, phone numbers, bank-card style strings, identity-like sequences, and other privacy-relevant fields to help users create safer document outputs. For content-heavy files, the app also provides AI document actions such as summarization, abstract generation, key-point extraction, rewriting, shortening, expansion, polishing, explanation, translation, tone adjustment, meeting-minutes generation, and follow-up chat based on the active file. Some features may require an in-app purchase or an active subscription. Subscription plans, if offered, will be displayed clearly inside the app before purchase. Payment will be charged to your Apple ID account after confirmation. Subscriptions automatically renew unless canceled at least 24 hours before the end of the current period. You can manage or cancel your subscription at any time in your App Store account settings.
