QR & Barcode Scanner by Gamma Play has crossed 800 million downloads on Android, and for most users it works without complaints. The 4.8 rating across 4.28 million reviews says as much. But a handful of specific issues drive the minority who go looking for QR & barcode scanner alternatives: interstitial ads that fire between scans, a privacy policy that covers behavioral data collection for advertising, and an auto-scan behavior that opens a URL the moment the camera recognizes a code with no confirmation step. For a tool that processes every QR code you point a camera at, that last detail is worth thinking about.
These 7 alternatives cover the same scanning territory. Some trade features for privacy, some add security checks that Gamma’s app does not offer. All of them are actively maintained.

Why people look for QR & barcode scanner alternatives
Ad interruptions. Gamma’s scanner shows banner ads during normal use and interstitial ads between actions. For a tool used in quick bursts throughout the day, the interruptions break flow more noticeably than in longer-session apps.
Behavioral data collection. The privacy policy covers collecting device identifiers and usage data to serve targeted ads. This is common in free Android apps, but it stands out for a camera-based tool that observes every code you scan.
No-confirmation auto-launch. Point the camera at a QR code and the app opens the linked URL immediately, with no “tap to open” step. For most legitimate codes this is convenient. For a code on an unfamiliar poster or a stranger’s business card, it opens a link before you have read what it points to.
App size. At around 45-50 MB installed, the app is larger than most dedicated scanners by 10-30 MB, which matters on lower-storage devices.
The best QR & barcode scanner alternatives
Google Lens — best for users who already have it
Google Lens is available on most Android devices through the Google app, Google Camera, and the built-in camera app on many manufacturers. It scans QR codes, reads and copies text from images, identifies objects, looks up products, and translates text. On most Android phones, the QR scanning component requires no additional install.
The scanning experience differs from a dedicated app. Results open inside Google’s search interface, and there is no dedicated scan history or QR generator.
Where it falls short: Google Lens is not a dedicated scanner. There is no scan history, no QR code generator, and batch scanning is not supported. Most functions require an internet connection.
Pricing:
- Free: everything
- Paid: none
- vs QR & Barcode Scanner: no ads, no behavioral data collection, no dedicated scanner UI
Migrating from QR & Barcode Scanner: No data to move. Scan history from Gamma’s app does not transfer, but Google Lens has no scan history anyway.
Bottom line: The right pick for occasional scanning on any Android phone. Not a replacement if you need scan history, a QR generator, or offline capability.
ZXing Barcode Scanner — best for privacy
ZXing Barcode Scanner (pronounced “zebra crossing”) is the open-source scanner that most of the Android QR scanning ecosystem is built on. The Apache 2.0 licensed codebase is publicly auditable at github.com/zxing. There are no ads, no analytics libraries, no third-party SDKs, and no server connections. Scans are processed entirely on-device.
It supports QR, Data Matrix, Aztec, UPC-A, UPC-E, EAN-8, EAN-13, Code 128, Code 39, ITF, Codabar, and RSS/Expanded formats. For the vast majority of barcodes encountered in daily life, the coverage is complete.
Where it falls short: ZXing receives infrequent updates. Some newer QR code variants and edge cases may not scan reliably. The UI has not changed materially in years and shows its age. There is no generator built in.
Pricing:
- Free: everything, always
- Paid: none
- vs QR & Barcode Scanner: smaller, faster to load, sends zero data anywhere; trades a more basic feature set for that
Migrating from QR & Barcode Scanner: Nothing to transfer. ZXing stores no scan history.
Bottom line: The strongest pick for privacy. No other free scanner sends less data. Skip it if you need a QR generator or a regularly updated app.
QR Code Reader by Scan — best overall replacement
QR Code Reader by Scan from Scan Inc is the closest like-for-like swap for Gamma’s scanner in terms of UX. Auto-detection works at comparable speed, scan history is maintained locally, and there is a built-in QR generator that handles URLs, Wi-Fi credentials, contacts, and plain text. The app is available on both Android and iOS, which makes switching easier for households that use both platforms.
The free tier carries banner ads. A paid tier removes them entirely for a low annual fee.
Where it falls short: The privacy policy is not significantly different from Gamma’s, so this is not a meaningful privacy upgrade. The improvement is in ad behavior (no interstitials) and cross-platform consistency.
Pricing:
- Free: full scanning, history, and generator with banner ads
- Paid: ~$3-4 per year (ad-free)
- vs QR & Barcode Scanner: comparable free tier; low-cost paid option
Migrating from QR & Barcode Scanner: Scan history does not transfer between apps. The new history starts from day one in the replacement app.
Bottom line: The easiest switch for users who want familiar behavior without changing their habits. Not a privacy upgrade; an ad-behavior and cross-platform upgrade.
Kaspersky QR Scanner — best for scanning unfamiliar codes
Kaspersky QR Scanner adds a safety layer that no other free scanner in this list provides: each URL is checked against Kaspersky’s threat intelligence database before the browser opens. If the link points to a known phishing site, malware distribution page, or flagged domain, the app stops and warns you before anything loads. For codes encountered in the real world, on posters, packaging, or business cards from strangers, this is a meaningful difference.
The app is clean, ad-free, and scans quickly. The URL check is near-instantaneous for most links.
Where it falls short: Android only. The safety check requires a live internet connection. Kaspersky is a Russian company, and some users are not comfortable routing scan data through their infrastructure regardless of the product; this is a judgment call based on your own threat model.
Pricing:
- Free: full scanning and URL safety checking
- Paid: none
- vs QR & Barcode Scanner: no ads; adds URL threat detection that Gamma’s app lacks entirely
Migrating from QR & Barcode Scanner: Nothing to transfer.
Bottom line: The right pick for anyone who regularly scans codes from sources they do not fully trust. Not suitable if Kaspersky’s data routing is a concern.
QR & Barcode Scanner Plus — best for product barcodes
QR & Barcode Scanner Plus by Digital Alchemy goes beyond QR codes with product barcode support that integrates price lookup and shopping comparison. Scan a grocery item, book ISBN, or retail barcode and the app surfaces pricing data from online retailers alongside the scan result. For anyone who wants to know what something costs online before paying in-store, this is a practical addition that Gamma’s scanner does not offer.
Where it falls short: The UI is more complex than a minimal scanner. The free tier carries ads. Price comparison data is sourced from third parties and is not always current.
Pricing:
- Free: full scanning and basic price lookup with ads
- Paid: small one-time purchase to remove ads
- vs QR & Barcode Scanner: similar ad model; adds product lookup
Migrating from QR & Barcode Scanner: Nothing to transfer.
Bottom line: The best pick if product barcodes matter as much to you as QR codes. Not worth switching if QR-only scanning is your primary use case.
QR & Barcode Scanner by Scan Team — best lightweight swap
QR & Barcode Scanner by Scan Team covers the same basics as Gamma’s app: fast auto-detection, scan history, QR generator, and Wi-Fi code support. It is a lighter install and carries a simpler privacy policy. Users who switched from Gamma’s scanner to this one consistently report the same scanning speed without the interstitial ad cadence.
Where it falls short: No meaningful differentiator from Gamma’s scanner beyond a slightly lighter footprint and different ad behavior. No security URL checking, no product lookup, no paid tier to remove ads entirely.
Pricing:
- Free: full feature set with banner ads
- Paid: none
- vs QR & Barcode Scanner: comparable feature set; different ad behavior
Migrating from QR & Barcode Scanner: Nothing to transfer.
Bottom line: A solid lateral move if the main complaint about Gamma’s scanner is the interstitial ad frequency. Not a privacy upgrade.
Trend Micro QR Scanner — best for work devices
Trend Micro QR Scanner is the other safety-focused option in this list. Like Kaspersky’s app, it checks each scanned URL against a threat database, in this case Trend Micro’s Smart Protection Network, before opening. The interface is clean, there are no ads, and Trend Micro’s enterprise security reputation means the app appears on approved lists for many corporate mobile device management policies.
Where Kaspersky and Trend Micro differ: Trend Micro has a stronger iOS presence and avoids the geopolitical questions that come with Kaspersky’s Russian ownership. For a personal phone, the distinction may not matter. For a managed work device, it often does.
Where it falls short: Requires internet for URL safety checks. No scan history or QR generator. The feature set is minimal.
Pricing:
- Free: full scanning and URL safety checking
- Paid: none
- vs QR & Barcode Scanner: no ads; adds threat detection; removes history and generator
Migrating from QR & Barcode Scanner: Nothing to transfer.
Bottom line: The better choice for work phones or corporate environments where Kaspersky’s infrastructure is not acceptable. Equally good for any user who wants free, ad-free scanning with a URL safety layer.
How to choose
Pick Google Lens if you scan a few codes per month and do not want another app on your phone. It is already present on most Android devices.
Pick ZXing Barcode Scanner if privacy is the primary concern. It sends no data anywhere, is fully open source, and handles the formats you will actually encounter in daily use.
Pick Kaspersky QR Scanner or Trend Micro QR Scanner if you scan codes from unknown sources, for example at events, on packaging from unfamiliar brands, or on printed materials from third parties. The URL safety check is a real protection that standard scanners skip.
Pick QR Code Reader by Scan as the cleanest like-for-like swap if you want familiar behavior, a cross-platform app, and a low-cost way to remove banner ads.
Pick QR & Barcode Scanner Plus if product barcodes matter and you want price comparison built in.
Stay on QR & Barcode Scanner by Gamma Play if the batch scan mode and CSV history export are part of your workflow. None of the free alternatives match that combination.
Frequently asked questions
Is there a completely ad-free QR scanner? Yes. ZXing Barcode Scanner is permanently ad-free and open source. Google Lens is also ad-free. Kaspersky QR Scanner and Trend Micro QR Scanner are both free with no ads. None of these require a subscription or one-time purchase.
Does Google Lens replace QR & Barcode Scanner? For basic code scanning, yes. For scan history, batch scanning, or a dedicated QR generator, no. Google Lens keeps no record of scanned codes and does not let you create them.
Which QR scanner is the safest to use? Kaspersky QR Scanner and Trend Micro QR Scanner both run URL safety checks before opening links. ZXing Barcode Scanner is the most private in a different sense: it processes everything locally and makes no network calls at all.
Can QR scanner apps steal my data? The apps themselves do not extract data from your device beyond what they need to function. The real risk is the URL a code points to, which can be a phishing or malware site. That is the specific threat Kaspersky and Trend Micro address with their safety checks.
What happened to QR Droid? QR Droid is still available but has not received significant updates in several years. The alternatives in this article are all more actively maintained.
