QR codes & barcodes, made simple

Create, scan and keep every code in one place.

Qroko turns text, links, Wi-Fi and contacts into scannable codes, reads codes with your camera or from a photo, imports e-tickets from a PDF, and stores everything in a tidy personal library.

What Qroko does

Four things, no clutter.

Create

Make a code

Build a QR from text, a link, a Wi-Fi network or a contact card.

Scan

Read a code

Use the live camera or decode a code from a photo in your library.

Import

PDF e-tickets

Turn a PDF ticket into one scannable card per code, with validity dates.

Organize

Your library

Search, edit, colour and add codes to Apple Wallet — all stored on your device.

Create a code

The Create tab.

Pick what kind of code you want from the chips at the top, fill in the short form, and Qroko formats the payload for you.

Code types

Make it yours

  1. Open Create and choose a type.
  2. Fill in the form and, if you like, a title, colour and image.
  3. Tap Save to library — Qroko saves it and jumps to your library.

Scan a code

The Scan tab.

Qroko reads QR codes and common barcodes — EAN, UPC, Code 128, Code 39/93, ITF, PDF417, Aztec and Data Matrix. A scanned barcode is remembered in its own format, so it's redrawn exactly as it was read.

On deviceThe camera only works on a real iPhone — the Simulator has no camera. QR decoding from photos works everywhere.

Import a PDF e-ticket

Several tickets, one tap.

Many vouchers bundle several tickets in one PDF — for example a family pass with a separate barcode per person. Qroko reads them all and creates one scannable card for each.

  1. On the Scan tab, tap Import a PDF e-ticket and choose the file.
  2. Qroko finds every barcode and reads the validity dates from the ticket.
  3. On the review screen, un-tick any code you don't want, set a title prefix, and check the dates.
  4. Tap Import — each code lands in your library, ready to scan at the gate.

Validity dates

On deviceNon-QR barcodes (like Code 128 or PDF417 on a boarding pass) are detected reliably on a real iPhone. In the Simulator, only QR is dependable.

Your library

The Library tab.

Every code you create, scan or import is kept here — on your device, nowhere else.

Add to Apple Wallet

Codes in your pocket.

Open a card and tap Add to Apple Wallet to keep the code as a pass. The pass uses the card's colour, shows the barcode, and — for a ticket with dates — displays the validity and greys out once it has expired.

NoteWallet controls the size of the code on the pass. For the largest scannable code, open the card in Qroko or use Share.

Languages

Settings → Language.

Qroko follows your iPhone's language by default, or you can pick one of eight from Settings.
