QR Code Reader ·
by App Lock LLC
Released in 2017 and still actively updated, QR Code Reader by App Lock LLC covers more than 15 code formats, adds scan history with folder organization, and supports batch scanning. At 78 MB it runs heavier than a basic camera utility, and the free tier is ad-supported with usage caps. The near-670K rating base is a credible signal of broad real-world usefulness, even if the subscription structure complicates the value equation for heavier users.
Broad format support with practical organization features
The core scanning proposition is strong. Beyond standard QR codes, the app reads EAN-8, EAN-13, Code39, Code128, Datamatrix, and Google Authenticator codes, covering retail, logistics, and two-factor authentication in a single install. Scan history, folder organization, and CSV export are practical features that most single-purpose scanner apps skip entirely. Batch scanning is a genuine standout for anyone processing multiple codes in sequence. Product and food detail lookups add a layer of context that raw scan data cannot provide. The breadth of format coverage alone separates this app from the stripped-down alternatives built into iOS.
Reliable scanning held back by file size
A 78 MB install is notably large for a utility whose primary job is pointing a camera at a code, and users on older or storage-constrained devices may notice that. That said, the 4.71 average across 669,000 ratings is a volume-weighted signal that day-to-day scanning is reliable for the vast majority of people. Update history through July 2026 indicates the developer is actively addressing bugs and compatibility. Qualitatively, apps in this category live or die on camera lock-on speed and false-positive rates; the rating volume here suggests neither is a chronic complaint. Ads on the free tier do interrupt the workflow between scans.
Free tier limited, subscriptions favor heavy users
The free tier functions, but scan caps, lookup limits, and ads make it feel provisional rather than complete. Three subscription tiers exist: monthly with a 3-day trial, quarterly, and annual. The 3-day trial is genuinely tight for evaluating whether Pro features justify ongoing cost, especially for occasional users who may not scan enough in three days to stress-test the limits. Annual billing offers the best per-scan economics for heavy users such as small business owners doing inventory or anyone relying on the product lookup feature daily. Casual users who scan once a week may never encounter the paywall at all.
Camera access necessary, privacy label review recommended
A QR and barcode scanner necessarily requests camera access, which is expected and unavoidable. Product and food lookups likely involve network requests that could carry device or usage identifiers. The developer name, App Lock LLC, does not obviously correspond to a scanning utility, which is worth noting when evaluating trust. The definitive source for what data is collected and how it is used is the App Store privacy nutrition label on the app's product page. We recommend reviewing that label before granting permissions, paying particular attention to data linked to your identity and any third-party advertising SDKs that support the free tier's ad model.
Functional design with minor ad workflow friction
The interface follows familiar iOS utility conventions, with a live viewfinder as the primary screen and history accessible from a persistent tab or menu. Folder organization and CSV export suggest the design accounts for power users, not just one-off scanners. Standard iOS accessibility features including Dynamic Type and VoiceOver should function as expected, since the app targets a 4-plus content rating and is built on native platform components. The ad placements on the free tier do add visual noise that can work against a clean scanning workflow. No significant departure from platform accessibility norms has been widely reported in the review base.
Actively updated across nearly a decade
A July 2026 update on an app first released in February 2017 is a positive signal. Nine-plus years of continuous availability, combined with a rating count approaching 670,000, indicates the developer has sustained the product through multiple iOS generations and App Store policy changes. Version 2.6.0 suggests incremental rather than wholesale revision, which is typical for a mature utility. The combination of recent update cadence and high rating volume gives reasonable confidence that critical bugs are addressed promptly and that the app will remain compatible with current iOS releases in the near term.
Pros
- Covers 15-plus code formats including Datamatrix, Code128, and Google Authenticator codes in a single app
- Scan history with folder organization and CSV export add practical utility beyond raw scanning
- Batch scanning saves meaningful time when processing multiple codes in sequence
- Nearly 670K ratings at 4.71 stars is a credible, high-volume signal of reliable everyday performance
Cons
- Free tier combines ads with scan and lookup caps, making it feel like a trial rather than a complete product
- 78 MB install size is disproportionately large for a utility built around camera scanning
- 3-day trial period is too short for occasional users to meaningfully evaluate whether a Pro subscription is worthwhile
