QR code scanner app maker

A QR code scanner app maker lets you build a scanner without the clutter and pop-ups of the ones in the store, or a scanner that does one specific job for your business. Describe what should happen after a scan, the AI agent writes the app, you test the flow in the emulator preview, and you download the APK to scan real codes with your phone's camera.

What your QR code scanner app will have

From the idea above, the agent builds:

• Scanner — the camera viewfinder with a clear scan frame, a flashlight button and a short vibration when a code is read.
• Result screen — what the code holds and what kind it is: link, text, phone number, email, Wi-Fi or product barcode.
• Smart actions — Open link after showing the full address, Copy, Share, Call, or the Wi-Fi network name and password with a Copy button.
• History — every scan with the date and type, searchable, with swipe to delete.
• Create — type text or paste a link, get a QR code, and save it or send it from the share menu.

Scans and history are kept on the phone. Scanning itself needs no internet.

Features you can ask for

• Continuous mode that scans code after code without leaving the camera, for stock counts.
• Export the history as a CSV file to open in a spreadsheet.
• Favorites for codes you scan often.
• A business card maker: your name, phone and email in one QR code.
• Colors and a logo in the middle of the QR codes you create.
• A warning when a link looks suspicious, such as a very long address or a lookalike domain.
• Your own app name, icon and theme.

Ideas to make it yours

Get it on your phone

1. Press Build this QR code scanner app and sign in with Google.
2. In the emulator preview, run a simulated scan and check the result screen, the actions and the history.
3. Ask for changes in plain words: "bigger scan frame", "beep on scan", "open the camera on the back tab by default".
4. Press Download APK, install it on your Android phone and allow camera access when it asks. Scan a few real codes: a link, a Wi-Fi code, a product barcode.
5. To publish on Google Play, build the signed APK and AAB from the same menu; the APK builder page explains the steps.

Test in bad light and at an angle. Most scanning complaints come from dim rooms and shiny labels; the flashlight button and a larger scan frame fix most of them.

Scanning safely

A QR code can hold any link, and people point their camera at codes on posters, menus and parking meters without a second thought. A good scanner protects them. Never open a link automatically: show the full address, highlight the domain, and wait for a tap. Ask for a clear warning on shortened links and addresses that do not start with https. Keep the camera permission request until the user first opens the scanner, with one line that says why. And keep history on the phone unless your use case needs sharing; a personal scanner has no reason to send anything anywhere.
