Support

Need help with QR & Barcode Reader? Most questions are answered below. If not, email [email protected] with your device model, iOS version and what happened — if a code doesn't scan, a photo of it helps. We read every message.

Scanning

The camera shows a black screen

The app needs access to the camera. Open the iPhone Settings app → Privacy & Security → Camera, and turn the app on. Then close and reopen the app.

A code won't scan

Hold the phone steady, 10–30 cm from the code, with the whole code inside the frame.
Make sure there is enough light and no glare on the code.
Supported codes are QR codes and EAN-8, EAN-13, PDF417 and Code 128 barcodes.
You can also scan a code from a photo or screenshot: choose the photo button and pick the picture.

Why do I see product details for some barcodes?

For product barcodes, the app looks the number up in Open Food Facts, a free public database. If a product isn't in it, no details are shown; you can search for the code on Google, Amazon or other sites from the result screen.

Is it safe to open a link from a QR code?

The app shows you the link first. Check that the address is what you expect before you open it, especially for codes in public places, and don't enter passwords or payment details on a page you don't trust.

History

Where are my scans?

In the History tab, on your device only. To delete scans, select them and tap the trash button. History isn't synced between devices.

Premium

I paid but premium isn't unlocked

Open the premium screen and tap Restore Purchases, signed in with the Apple ID you bought with. If it still doesn't unlock, email us the date of purchase and the plan; please don't include your Apple ID password.

How do I cancel my subscription?

Open the Settings app → [your name] → Subscriptions → QR & Barcode Reader. Deleting the app does not cancel it.
