QR & Barcode Scanner

What it is

QR & Barcode Scanner is a utility from Gamma Play, listed under Tools. It is free, rated Everyone, and has been on Google Play since March 2015. The latest update was on 2026-10-19. It reads QR codes and barcodes, and the developer describes it as the fastest option available, which is a self-assessment and not a measured claim.

What it does well

The listing says scanning starts on its own once the camera points at a code, with no button press, photo or zoom adjustment needed. It reads many formats, among them plain text, web links, book ISBNs, store products, contacts, calendar entries, email, places and Wi-Fi details, and offers actions suited to each type. You can also scan from the gallery or from images shared in from other apps. The app generates QR codes too, including from clipboard content, and lets you change colors and theme. Further extras named include a flashlight, pinch to zoom, dark mode, favorites, a batch mode for several codes at once, and export to CSV or TXT files.

What the ratings show

The ratings are the strongest part of the data. The app averages 4.8 across 4,790,109 ratings and has 500,000,000+ installs. Of those ratings, 89.4% are five stars and 6.4% are four. Only 2.3% are one star, 0.5% two stars and 1.3% three stars. For a tool used by that many people, that is a very clean split.

Where it falls short

The description reads like a block of search keywords, with the same phrases repeated over and over, so it is hard to pull out clear details. It does not say whether the app shows ads, sells anything or asks for a subscription. Free apps in this category often rely on one of those, but the listing is silent, so check before you rely on it. The text is also cut off in the data, so the full permission picture is unknown.

Anyone who wants a quick scanner and a small QR generator will find the feature list ample. With near-universal approval in the ratings, it is a safe first thing to try.
