QR Master: Scanner & Generator

Devs Wizard

About this app

QR Master is a fast, private QR code scanner and generator — no accounts, no tracking, and it works 100% offline.

SCAN ANYTHING, INSTANTLY
Point your camera at any QR code and QR Master detects it automatically — no button to press. Smart actions read what you scanned and offer the right next step:
• Website → open in browser
• Wi-Fi → connection details ready
• Contact → save to your contacts
• Email / Phone / SMS → act in one tap
• Location → open in maps
• Plain text → copy or share
No camera handy? Import a QR from any photo in your gallery.

CREATE ANY QR CODE IN SECONDS
Generate QR codes for links, Wi-Fi, contacts, email, SMS, phone numbers, location and plain text. Customize colors, corner style and error-correction level, then save as a crisp PNG or share it anywhere.

SHARE WI-FI THE EASY WAY
Turn your network into a QR code so guests connect without typing the password.

ORGANIZED, SEARCHABLE HISTORY
Every code you scan or create is saved locally and auto-sorted by type. Search, filter, favorite and manage — all on your device.
