Try ScanLens for yourself
Privacy-first scanning with no ads, no account required, and a lifetime option. Free to start.
A fair side-by-side comparison of two iPhone document scanner apps. Privacy, features, OCR, and pricing — based on what each app actually does, not marketing claims.
Yes, we make ScanLens. That makes us biased, and you should keep that in mind. We have tried to write this page the way we would want a competitor to write it about us: factual, current as of April 2026, and willing to acknowledge what the other app does better. If you find anything inaccurate, email us at [email protected] and we will update it.
Pricing and features change. Verify current details on each app's App Store listing before making a decision.

This is the area where the two apps differ the most, and the difference matters for some users more than others.
ScanLens performs all scanning, edge detection, image enhancement, and OCR locally on your iPhone using Apple's Vision framework. Documents only leave your device if you explicitly choose to share them, export them, or sync them to a cloud service that you control (iCloud, Google Drive, Dropbox, or OneDrive). You do not need to create a ScanLens account. There are no analytics SDKs collecting usage data, and the company behind the app, BITFORGE PTE. LTD., does not have access to your documents.
CamScanner is a cloud-first product. Scanning and OCR rely on its server infrastructure, and many advanced features require uploading documents to the company's cloud. Sync, sharing, and team features are tied to a CamScanner account. Whether this is acceptable depends on the sensitivity of what you scan: marketing receipts and shopping lists are different from medical records and tax documents.
In August 2019, the free Android version of CamScanner on Google Play was found to contain a malicious advertising SDK from a third-party provider. Google removed the app, the developer removed the offending SDK, and the app was reinstated. The iOS version was not affected by that specific incident. This is widely reported and verifiable from coverage by Kaspersky, Reuters, and others.
Bringing this up is not to suggest CamScanner is unsafe today — it has had many years and many releases since. It is to make a broader point: when a scanner app embeds third-party SDKs (for ads, analytics, attribution), the developer cannot always guarantee what those SDKs do. ScanLens addresses this by not embedding ad or analytics SDKs at all.
CamScanner uses a subscription model. Pricing on the App Store as of early 2026 is approximately $4.99 per month or $49.99 per year for the Premium tier, with additional Business and Enterprise plans available for teams. CamScanner does not currently offer a lifetime purchase option. The free tier shows ads and watermarks exports. Verify current pricing on the App Store before subscribing.
If you scan documents regularly for years, the math eventually favors a one-time purchase. $79.99 for ScanLens Lifetime equals roughly 16 months of monthly premium or 2.7 years of yearly premium. After that, every year is free. Subscriptions also create the risk of losing access if you stop paying — which can be especially frustrating for an app you used to organize an archive.
CamScanner is generally safe for everyday use today. The 2019 malware incident, which affected the Android version on Google Play through a third-party advertising SDK, was resolved at the time. The current versions on Apple's App Store and Google Play go through standard platform review. The bigger ongoing concern for sensitive documents is that scanning and OCR are processed on CamScanner's servers, which means the company has access to your documents. If that is acceptable for your use case, CamScanner is fine.
Both apps offer accurate OCR for clean printed text. CamScanner uses cloud-based recognition that benefits from large server-side models. ScanLens uses Apple's Vision framework, which runs entirely on-device using the Neural Engine. For most everyday documents the difference is negligible. CamScanner historically supports a larger raw language count, but ScanLens covers 50+ languages and has the privacy advantage of never sending your document anywhere.
Yes. CamScanner lets you export documents as PDF or JPG and save them to Files, Photos, or any cloud service. Once exported, you can re-import them into ScanLens or any other PDF tool. There is no automated migration tool, so it is a manual process for documents you want to keep.
The free tier of ScanLens is genuinely usable for basic scanning: unlimited document scans, 3 pages per scan batch, basic image filters, and PDF export. Premium features such as OCR, cloud sync, e-signatures, advanced PDF tools, and watermark-free export require a subscription ($4.99/month, $29.99/year, or $79.99 lifetime). There are no ads in any tier and no account is required to use the free tier.
CamScanner's free tier on iOS has shown ads historically. The premium tier removes them. ScanLens has no ads in any tier, including the free tier.
