Top pick for rating accuracy: users have trusted it for years and describe specific real-world workflows.
Praised
Auto-crop and manual crop with zoom work precisely. Users describe it as perfect for photo-to-PDF and easy to use with great features in daily professional contexts.
Complaints
Email sending broke after one update and never recovered. Folders cannot be sorted manually, so the order is random and becomes a problem with large archives.
Best for: Field professionals and anyone who scans daily and needs organized document storage.

A time-tested scanner with solid file organization, but export has been glitchy lately.
Praised
Users keep coming back year after year for the predictability: shoot, crop, send. The file system handles large archives without losing navigation.
Complaints
Email delivery stopped working for some users after an update and documents don't get through. Auto-capture mode requires manual confirmation for each page, slowing down multi-page scans.
Best for: People who store documents inside the app and occasionally send them by email or to the cloud.

A reliable professional scanner with a great quality-to-file-size balance, but stability dropped after recent updates.
Praised: Users highlight speed and clarity as the main draw: 'unbelievable speed and clarity.' The balance between image quality and file size is a rare strength that experienced users notice.
Complaints: After the latest update the app crashes regularly when shooting two pages back to back. Dropbox and Google Drive sync stopped working for some users.
Best for: Professionals who need sharp scans with file size control and reliable cloud export.

A feature-rich PDF toolkit with a wide range of operations but a rough UX in complex workflows.
Praised: Compression, merging, splitting, and JPG conversion all in one app. Users say it replaces Acrobat for everyday tasks.
Complaints: Every action exports a new file to a new folder, so you can't chain multiple operations in sequence. The app crashes without auto-save, which means all work is lost.
Best for: People who work with PDFs regularly and need a wide range of operations without Adobe.

A fast and convenient scanner with built-in fax, but unreliable email delivery undermines trust.
Praised: Flattens crumpled receipts and sends a PDF right away without extra steps. Users appreciate the speed and folder organization.
Complaints: Emails with scanned documents can take hours or never arrive at all. Documents don't sync to the cloud and disappear when the app is reinstalled.
Best for: Field workers and freelancers who need to quickly send a document or receipt without a scanner nearby.

Strong OCR and auto-crop, but export became confusing and unstable after updates.
Praised: Page auto-crop is accurate: users describe a 'perfect scan' with no manual corner adjustment. Integrates with Adobe cloud without extra steps.
Complaints: The save button disappeared in one update and people can't figure out how to download a PDF locally. Some users lose pages when exporting multi-page documents.
Best for: Office workers in the Adobe ecosystem who need precise cropping.

A mature PDF editor with solid annotation tools, but it broke user trust by revoking already-paid features.
Praised: Precise text alignment with snap guides when adding text. Annotation for academic work with Apple Pencil. Users from 2017-2018 praise stability and speed under the old model.
Complaints: The company revoked features from users who had paid for a lifetime license. PDF tabs close when switching between apps, and some articles fail to load fully.
Best for: Those willing to subscribe who need a professional editor for annotation on iPad.

A veteran scanner that got ruined by updates and a subscription paywall.
Praised: '10 documents in a minute.' People have kept it for years for its reliability and simplicity of the basic flow.
Complaints: Every major update complicates the interface instead of simplifying it. The subscription wall blocks document sending, which is the only reason people open the app.
Best for: Anyone who scans occasionally and wants the fewest steps from button to PDF in their inbox.

The proven ABBYY OCR engine in a mobile wrapper, with degradation since switching to a subscription model.
Praised: Voice recognition is accurate. Long-term users trust the scan and OCR quality for professional documents including invoices and legal papers.
Complaints: After recent updates, OCR adds phantom text. Auto-capture scans the same page multiple times. The output format silently changed from PDF to JPEG.
Best for: Professionals with heavy document volumes who are willing to pay a subscription and can accept instability in new versions.

A functional scanner with good recognition, but recent updates broke stability.
Praised: Supports drag-and-drop for photos and documents directly into the app. The basic path of scanning receipts daily and emailing them works without extra steps.
Complaints: When editing, color documents get converted to black and white, which breaks scanning of artwork and color forms. The trash folder in new versions freezes when you try to empty it.
Best for: People who scan receipts and documents regularly and want to store them in organized folders.

A proven scanner with a good track record, but auto-capture is degrading in recent versions.
Praised: Cloud storage connections and fast scanning on the phone. Users keep the app for years for its reliable core cycle: shoot, save, send.
Complaints: Auto-capture has become finicky: it says 'get closer' when the document already fills the screen. In recent updates the feature only works under ideal lighting conditions.
Best for: People who scan documents on the go regularly and want cloud sync.

One of the oldest mobile scanners with a solid user base, but email integration is broken and the paywall is aggressive.
Praised: Document recognition and scan quality have been consistent for years. Works as a reliable tool in the field and while traveling.
Complaints: The email send button does not work in the current version. Flash removes shadows unevenly and the final scan is sometimes darker than the original.
Best for: Users who need an offline scan without sending, or longtime users who haven't updated.

Once a reliable scanner with solid photo processing, now degraded after the camera engine changed in newer versions.
Praised: Batch scanning into a single PDF and sharing via Gmail. Long-term users describe it as a precise tool for receipts and multi-page documents.
Complaints: After a forced switch to the ultrawide lens, small text on receipts became unreadable. The frame border in new versions crops the useful scan area.
Best for: People who scan standard documents and receipts regularly, on older versions of the app.

A mobile fax app with a clean interface but unreliable delivery.
Praised: The built-in document scanner works well. The automatic cover letter looks professional and saves time.
Complaints: Fax delivery is unreliable: multiple users waited 2-3 minutes per page and the fax never went through. The sending mechanism is not stable enough for critical documents.
Best for: People who send a fax occasionally and can accept some unreliability.

A simple workhorse scanner that handled daily tasks well, but auto-capture has become too aggressive.
Praised: For office routine it works without extra steps: shoot, get a PDF, send. Long-term users describe it as a lifesaver for document work.
Complaints: After an update, auto-capture fires too fast and doesn't let you adjust the angle before it locks in. Pages look less sharp after manual correction, according to recipients.
Best for: Staff members who need to send a few pages quickly and don't need precise frame control.

A fast photo-to-PDF converter with a friendly interface, but fragile: all files are stored locally and lost when you delete the app.
Praised: '40 minutes with other apps, 40 seconds with this one.' The core scanning engine gets praise for clean output.
Complaints: Auto-alignment distorts documents with curled corners, stretching them to an unreadable size. All files live locally and vanish completely when the app is deleted.
Best for: Students and one-off tasks. Not suited for anyone storing important documents long-term.

A veteran scanning app with a long-term user base, but support has been declining and it has issues on iPhone 14 Pro.
Praised: Simple scanning flow and a wide range of export options. Lawyers and field workers use it to scan documents on-site without extra equipment.
Complaints: Documents are lost after a phone switch and support doesn't respond. Autofocus is broken on iPhone 14 Pro due to the wide-angle camera and the developer hasn't updated the app.
Best for: Experienced users on older devices who are tied to their document history in the app.

A simple scanner with basic quality, ruined by broken email export and inappropriate ads.
Praised: Detects documents from as far as 1.5 meters away. Long-term users appreciate the simplicity and speed of basic scanning.
Complaints: Email sending is systematically broken: documents get stuck in the outbox or never reach the recipient. Ads inside a work app are a problem for professional use.

A market veteran that degraded from a convenient scanner into an aggressive subscription funnel.
Praised: Previously valued for scanning speed and easy document sending without extra steps. Scan quality itself was described as good enough for work tasks.
Complaints: Core features like PDF compression and watermark removal are locked behind a subscription that users discover only after shooting. Full-screen ads appear even for paying users.
Best for: People who scan a single page once in a while and don't care about quality.

A standard mobile scanner that handles one-off tasks but is unreliable under regular use.
Praised: Automatically straightens a page when the phone is held at an angle. One user used it for university admission transcripts and was satisfied with the result.
Complaints: Scan quality is inconsistent and depends on lighting and the angle the phone is held. The built-in eraser tool charges separately for each action.
Best for: People who scan occasionally and don't rely on consistent OCR quality.

An OCR scanner with strong printed-text recognition and weak handwriting recognition.
Praised: Printed text from photos converts accurately and quickly. Users describe real work scenarios: text from books, work documents, contact sheets.
Complaints: Handwritten text recognition produces errors and is worse than iOS built-in OCR. No batch upload: each image must be added one at a time, which kills productivity at high volume.
Best for: People converting printed documents to text. Not suitable for handwriting.

The former Scanbot with strong auto-crop and cloud sync, ruined by aggressive monetization junk after the ownership change.
Praised: Auto-crop works precisely and filters improve readability. Automatic upload to cloud storage (iCloud, OneDrive) is the key feature for regular users.
Complaints: Crashes increased after the ownership change (formerly ScanBot). Scan quality has degraded according to long-term users. Intrusive notifications with AI upsells and occasional double charges through pop-up upgrades.

A basic PDF editor for one-off form filling, an Adobe alternative without deep editing.
Praised: Quickly handles form filling without an Adobe subscription. The interface is simpler than professional editors.
Complaints: Color images get converted to black and white during editing. Document formatting is not retained on re-open as the app doesn't recognize its own markup.
Best for: People who fill a form once a month and don't want to pay for Adobe.

A file manager that was good years ago and has degraded into an aggressive subscription model.
Praised: The built-in browser and music player kept people using the app for years. It worked as an iTunes replacement without constant pop-ups.
Complaints: Files are hard to find after saving and folder navigation is confusing. Several users report the app stopped opening entirely, locking them out of their saved files.
Best for: People looking for a file manager with a browser, not a document scanner.

A feature-rich scanner with a broad toolset that breaks in edge-case scenarios.
Praised: Extensive set of tools for photo and PDF work. Simple tasks like scan and save are fast and reliable.
Complaints: AI editing is unpredictable: it can delete all matching elements instead of just the one you selected. After updates, auto-scan stops saving the crop.

Praised: The folder system is convenient for keeping documents on hand. Long-term users value having their archive accessible on the phone.
Complaints: The fax feature breaks regularly and has no proper password recovery on reinstall. Documents are lost when the app crashes on 25+ page scans.

A PDF editor with powerful capabilities, but the interface is cluttered with AI features and annotations disappear.
Praised: Paid subscribers value PDF markup and form work on desktop. Basic PDF reading and document navigation are stable.
Complaints: Markup (annotations) disappears on reopen for about half of users. Exporting a PDF with markup takes too many steps and often doesn't work as expected.

A technically functional scanner with filters and batch shooting up to 30 pages, locked down by a paywall for any export.
Praised: Lets you scan up to 30 pages at once with filters to improve readability. PDF conversion is fast.
Complaints: After scanning, any action with the file, export, sending, or printing, requires a subscription. Users who tap 'move document' get a rating prompt instead of the action.

Praised: Converts document photos to PDF quickly, the interface is simple. A few users note its convenience for storing standard paper documents.
Complaints: OCR struggles with handwriting according to the users' own five-star reviews. No direct PDF-to-email: you have to save to cloud and send from there.

A scanner that destroyed itself by tying everything to Evernote and putting a hard paywall on basic export.
Praised: Previously: fast scan and instant send to Evernote without extra steps. The image quality at capture is described as good.
Complaints: The app constantly signs out of Evernote and re-login takes multiple attempts. Saving a scan to Camera Roll or sending it directly without Evernote is now paid.

Praised: In basic scenarios, converts photos to PDF quickly. Some note its convenience for work documentation.
Complaints: Paying users lose features over time: the email button stopped working, Dropbox disconnected, and Google Drive blocked access due to an unverified integration. OCR produced unreadable output on a current iPhone.

An image-to-PDF converter with aggressive monetization and an unreliable subscription cancellation mechanism.
Praised: Basic screenshot-to-PDF conversion works quickly without extra steps. The task completes in a trial.
Complaints: The subscription keeps charging after cancellation and there is no cancel button in the interface. One user wrote directly that the conversion is 'fake' and doesn't work.

About scores
Two scores — two sources
They help compare apps, but they don’t replace checking your own job.
Review score · up to 100
The stored score from inApp research on review texts. It rates the app overall in the archive, not the reliability of any one feature.
Store rating · up to 5
The rating from the app’s page when the data was collected. The current rating and version may differ.
In the archived sample for this topic: 52 apps and 22,040 reviews read. That is the total size of the research, not the number of reviews per app.
A gap between the scores doesn’t prove manipulation. The calculation date and the full scoring method aren’t in the mobile archive. Compare the job descriptions and the source quotes, and check the terms in the current version.
