Every QR code, every barcode — scanned, generated, saved. If you have ever fumbled with a built-in camera in a dim restaurant, or hunted through screenshots for that WiFi QR you scanned three months ago, a proper QR tool earns its place on the Home Screen. This is a complete QR code reader, barcode scanner and QR code generator in one app, with a fast camera, a tidy scan history and design tools for the codes you create yourself. Nothing you scan or generate leaves the device, no account is required, and the app never asks for an email just to read a code from a menu. Every feature described below is unlocked only with an auto-renewable subscription purchased inside the app. New users receive a 3 day free trial; you may cancel anytime during the trial to avoid being charged. Open the camera and the qr scanner reads QR, barcode, UPC and EAN even in low light, with auto-zoom for distant labels and a torch toggle for the back row of a warehouse. The barcode reader handles damaged or smudged codes that the built-in camera gives up on, and a scanner app history saves every scan with the location, timestamp and decoded payload so you can find that wifi qr you used at a hotel last winter without retyping the password. Generate QR codes for URLs, plain text, WiFi credentials, contacts, email, SMS or location, and dress them with your logo, brand colors, eye styles and gradients for a custom qr code that still scans cleanly on cheap printers. The qr maker also covers volume work: batch generate from CSV when you need a hundred unique codes for a campaign, an event, a numbered ticket roll or a sticker run, and the barcode generator can sequence numeric SKUs across an entire product line in seconds. Pin the qr widget to your Home Screen for instant scan or share, drop QR passes into Apple Wallet for boarding-style use, and export print-ready PDF, SVG and PNG so a designer can drop your code straight into a poster, a packaging file or a brochure. Scan history can be tagged, starred and exported, and a focused code scanner mode strips everything but the camera frame when you just want to read fast. This qr tool ships in 39 languages with full VoiceOver support, and everything works offline — the camera does not phone home, your library lives on your device, and there is no third-party server in the loop. Designed to serve a cafe printing menu QRs, an event team checking tickets, a marketer running campaign codes, a parent saving their home WiFi QR for guests, and anyone who simply scans a lot. Recent codes appear in the qr history with a single tap to copy, open or share, and saved generated codes can be edited in place when a URL changes after print. Unlock with Pro: • Unlimited scan and generate history (free: last 100) • All QR design styles, logo embedding and color gradients • Batch generation from CSV import • PDF, SVG and PNG print-ready export • Apple Wallet QR passes and ad-free interface Subscription Pricing & Terms Features require a subscription.

Verdict
