Atharok's Barcode Scanner, version 1.26.3, was updated on July 10, 2026. It reads QR Code, Data Matrix, PDF 417 and AZTEC, plus 1D formats such as EAN 13, UPC A and Code 128. It can also look up food through Open Food Facts and cosmetics through Open Beauty Facts. It is free, 7.9 MB, GPL-3.0-only licensed, and shows no ads.
Bluetooth QR & Barcode to PC by fabik sends a scanned value as text to a connected Bluetooth device, such as a PC, with no software needed on the receiving side. It works offline, offers different keyboard layouts, and has no ads or in-app purchases. Version 2.3.2 is 11.2 MB, updated September 15, 2026, under GPL-3.0-only.
Secure QR Share by Jonathan Drolet passes passwords and links between people who are nearby. The sender enters text and a shared PIN, the app encrypts it with AES-256 and shows a QR code, and the receiver scans it and enters the same PIN. The developer says there is no server or cloud. It is 19.1 MB and MIT licensed.
QRshare by mrwm works in the other direction: it creates QR codes from links, contacts or text sent through the share menu. You can edit the text, then copy or share the code. At 0.8 MB it is the smallest app on this page. Version 1.0.22 dates from December 7, 2025, with an Apache-2.0 license and no ads.
QR Code Scanner by Triple Tap Limited shows no ads and has no in-app purchases. The developer says it works without an internet connection, so scanning does not depend on a signal.
Ad status and the labels in our catalog data decide the order. The small ad-free apps come first, followed by one more app that also shows no ads. Install counts and ratings come from Google Play and appear only where we have them.
Six of the 11 apps show no ads. All five picks on this page are among them. QR & Barcode Scanner, QR Code Scanner & Scanner App, FreeScan, QRbot and QR & Barcode Scanner Launcher all show ads.
QR & Barcode Scanner leads with over 500 million installs and a 4.8 rating. QR Code Scanner & Scanner App follows with over 100 million and the same rating. FreeScan QR Code Scanner has over 50 million installs and a 4.4 rating.
Pick by task, not by install count. For reading product barcodes, Barcode Scanner covers the most formats in this list. For typing scanned values into a PC, Bluetooth QR & Barcode to PC is the specific tool. For handing a link or password to someone beside you, QRshare and Secure QR Share cover the two cases. Note that QR & Barcode Scanner Launcher is described as a launcher app, so it works differently from a normal scanner. Check the ads and in-app purchase flags on each listing before installing.
