From first launch to advanced Pro workflows — a complete guide to every flow, gesture, and shortcut in QR & Barcode Scanner.
Tap the center tab (the scan icon) from anywhere in the app. The camera opens in under 200ms. Back camera is the default. The scan-line starts sweeping immediately — no extra taps.
Align the code within the reticle. The lime corners mark the target area. For small codes, pinch to zoom (1× to 5×). For damaged or blurry codes, hold still and let the auto-zoom assist. In low light, enable the torch — it's faster than ambient light compensation.
The moment a valid code is fully in frame, the camera feed pauses, a haptic pulse fires, and a beep sounds (both are toggleable in Settings). The payload is classified by type and the result card slides up with the right action ready.
The result card shows the decoded type as a chip, the payload formatted for readability, and the primary action as a full-width button. The right action is always front and center: "Open" for a URL, "Connect" for Wi-Fi, "Add contact" for vCard — no hunting through menus.
Tap the + button from Home, or use a Quick Action chip (QR Code, Barcode, Wi-Fi, Contact). The Generator sheet opens with a template grid — 14 types for QR, 6 for barcode.
Each template has the exact fields you need. URL gets a single field with protocol validation. vCard gets structured fields: name, phone, email, org, address. Wi-Fi gets SSID, password, encryption type. The QR preview updates with each keystroke.
Tap "Customize" to open the QR Designer. Pick from 8 foreground colors and 6 backgrounds, switch dot style (Square, Rounded, Circle, Diamond) and eye style (Square, Rounded, Circle, Leaf, Diamond), embed a logo image, and pick a printable frame.
Tap Save to add to history (optional folder + label). Tap Share for the system share sheet. Tap "Save to Photos" for a PNG. Tap Print for AirPrint or Android Print. Pro users can tap "Make Dynamic" to convert a static QR into a tracked, editable Dynamic QR.
Tap any point on the camera feed to manually set the focus and exposure point.
Pinch outward on the camera feed to zoom in, from 1× to 5× optical.
Double-tap the camera feed to flip between front and back camera instantly.
In History or Folders, swipe right on any item to archive it immediately.
Swipe left to delete a history item. Confirmation prompt appears before permanent delete.
Long-press any item in History to enter multi-select mode. Select more items to bulk move, delete, or export.
Pull down on the History list to reveal the search bar and start typing.
Volume Up or Down triggers a scan capture on compatible devices — one-handed use.
3D Touch or long-press the app icon for quick actions: "Scan now", "New QR", "History".

Asked the first time you tap the Scan tab. Required for live scanning. QR & Barcode Scanner never records or uploads camera frames.
Asked when you tap the gallery icon or "Save to Photos". Only reads or writes photos — never uploads.
Only asked if you enable "Tag scans with location" in Settings. Never asked proactively on first launch.
