Optical character recognition (OCR) functionality based on Tesseract via Intents
About this app
This app bundles OCR functionality (based on Tesseract) that can be called from other apps via Intents. It listens for Intents with action "org.totschnig.ocr.action.RECOGNIZE" and expects an Uri pointing to a JPEG file as data. The recognized text is passed back in the extra "result" as an object of a parcelable data class Text, that must be copied into the client app.
This app is not intended to be useful stand-alone. It was created out of the motivation to not blow up the size of an application that makes use OCR for a feature that is not needed by all users. Currently it is used by My Expenses for scanning receipts.
Before you start using it, you need to configure the language that Tesseract should use, which triggers the download of the necessary trained models, hence the need for INTERNET permission.

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)

Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be org.totschnig.ocr.tesseract is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 2.4 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall OCR (Tesseract) first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of OCR (Tesseract), and a listing is removed when the evidence for it stops holding up.
