Perfect OCR gives you both a general purpose OCR app and a document scanner. Now you can scan and OCR your letter-size or A4 documents with an accuracy of 90% or more, edit, copy and store the recognized text, and e-mail your documents as PDF files with text, SINGLE page image, or both together! NOTE: To ensure the advertised results it is important that you follow the OCR TIPS below (or in the app's help). Perfect OCR scans your documents using advanced image-processing algorithms to eliminate uneven lighting and shadows and improve contrast. The result is the clearest and most readable scans possible from the iPhone's camera. Perfect OCR also offers SureScan, our proprietary scanning mode that delivers sharper images with less jitter or smear. Our unique "Email to myself" feature lets you send documents to a predefined address, or even upload them to an online storage service like Evernote or Box.net, with a single tap. Uploading documents to online services via email is fast, secure, and can be done even if you're temporarily off line. Refer to app help for details. All processing happens on your iPhone, and the confidentiality of your data is never compromised. There is also no subscription fee, and no Internet access is needed to scan documents or run OCR. PERFECT OCR FEATURES: • Letter-size or A4 page OCR with accuracy of 95% for model 3GS, 98% for iPhone 4, and up to 90% for 3G • OCR languages: English, French, Spanish, German, Dutch, Italian, Portuguese, Swedish, Russian, Polish, Hungarian, Czech and Ukrainian. • Email multipage PDFs with text, SINGLE page image, or both • Automatic document edge detection and perspective correction • Multipage text recognition with accuracy indicator • Text editing and copy-to-clipboard operations • Built-in OCR text archive with file sharing via iTunes • "Email to myself" feature • Email text and image files (.TXT + .JPG), or save image to library • Searchable PDFs with document images (single page) • Preserves simple text formatting • Option to auto-remove line breaks • SureScan mode for jitter-free scans • Simple yet powerful user interface • Instant brightness, rotation, and color controls • Compact attachments with adjustable size IMPORTANT TIPS FOR OCR: • Make sure your document is flat and well lit. Hold your iPhone still while shooting. • Always scan documents using "SureScan 3x" mode. • Glossy paper may not work well (avoid glare). • When scanning books keep the pages as flat as possible and your iPhone parallel to the surface. • Perfect OCR cannot recognize handwritten, very large text or spreadsheets correctly. • Make sure to select the right language for OCR in app settings.

SyncCal allows you to share your iOS calendars (e.g. iCloud and Exchange calendars) via Google Calendar with other people. E.g. if you would like to share your work calendar with your family, you can do it this way. And if you (or your employer) doesn't want the events' details to be uploaded to Google Calendar, you can only upload empty events instead, so that your family knows at least the times of your events. Just install SyncCal, enter your Google Calendar account, select which calendars should be synced and tap "Start". Afterward it will copy the selected calendars into new calendars in Google Calendar. It will also automatically keep them up-to-date by using background refresh and push notifications. It can also be configured to automatically sync when you leave your workplace. Just turn "Sync when leaving this place" on when you are at work. SyncCal will save the location and afterward it will automatically sync every time you leave your workplace. iOS' birthday calendar can also be synced into a Google calendar this way.

Verdict

The call

The clearest difference is rating: Perfect OCR at 4.7 against SyncCal's 3.5. Perfect OCR also leads on ratings volume (118 vs 22). SyncCal's advantage is review sentiment (76% vs 65%) and iOS requirement (8.0 vs 16). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Perfect OCR holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: Perfect OCR has 118 ratings behind it against 22, so its average is the more settled of the two. Written reviews complicate that: 65% of Perfect OCR's written reviews are positive against 76% of SyncCal's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Perfect OCR ships an update every 2 months, SyncCal every 3 months. The most recent releases landed on September 24, 2026 and September 25, 2026 respectively.
