This is a QR code and barcode scanner built around how people actually use codes in real life — not just one scan at a time, but across every format, every content type and every situation where a code appears and you need to know what is inside it immediately. The app reads. The app generates. The app remembers what you scanned. Here is when each part becomes useful. WHEN YOU JUST NEED TO SCAN SOMETHING FAST * Point the camera at any QR code or barcode and the result appears instantly — no button press, no loading screen * The scanner recognizes URL, text, phone number, email, SMS, WiFi credentials, vCard contacts, geographic coordinates and standard barcodes automatically * Each result type opens the right action directly: a URL goes to the browser, a phone number to the dialer, WiFi connects without typing, a vCard saves as a contact WHEN YOU HAVE MULTIPLE CODES TO GET THROUGH * Switch to Batch Scan and move through a stack of QR codes or barcodes without stopping between each one * Every scanned result is captured and logged as you go — nothing is lost, nothing needs to be re-scanned * Use this when you are processing inventory, checking in items, scanning products in sequence or any situation where stopping after every single code slows you down WHEN YOU NEED TO CREATE A CODE FROM SCRATCH * Open the Generator and choose what type of code to create: URL, plain text, phone number, email, SMS, WiFi network, vCard, location or standard barcode * Fill in the details, generate the code and save or share it immediately — no design tools, no third-party service required * Use Creator to produce codes for business cards, product labels, links, contact sharing or any use case where you need a scannable code ready fast WHEN YOU WANT TO GO BACK TO SOMETHING YOU SCANNED * Every scan is saved automatically to History with the content type, the result and the time it was scanned * Open any past entry to copy the result, trigger the action again or share it without rescanning * History keeps your scanned codes organized so nothing useful gets lost between sessions WHAT'S INSIDE QR Code Scanner — instant recognition of all standard QR code formats with automatic content type detection Barcode Reader — full barcode scanning across common retail and inventory formats Batch Scan — continuous multi-code scanning that logs every result without stopping between scans Generator and Creator — QR code and barcode creation for all supported content types, ready to save or share History — complete log of all scanned codes with content, type and timestamp for every entry Supported Content Types — URL, Text, Phone, Email, SMS, WiFi, vCard, Geo coordinates, Barcode SUBSCRIPTION & ACCESS Important: Subscription required; no free content.
