Thanks.

I am in need of a better scan process for my receipts. This sounds like a plausible ingress tool. I'll give it a try.

I always had trouble with OSS. My fat fingers can never square off the documents properly. Actually, I wasn't able to install Open CV manager for some reason. I think that was the real reason I stopped using OSS. I think I mixed up apps about the problem squaring docs.

Thanks for sharing.

I've been using [OSS Document Scanner](https://github.com/ossdocumentscanner/OSS-DocumentScanner) for a while now. I'll check this out.

I have struggled for years to find a good, open source android scanner to use on my graphene OS pixel. I think my search is over. I installed MakeACopy a few weeks ago, and it has really performed well. The app is uncluttered and intuitive. Scanning, saving and sharing files is simple.

I know the universe of people who might find this app useful is limited, but if you need a good open source mobile scanner without Apple or Google ties, give it a try.

MakeACopy is an open-source document scanner app for Android that allows you to digitize paper documents with offline OCR functionality. The app is privacy-friendly and works completely offline — no cloud connection, no tracking.

• Camera scanning: Capture documents using your device’s camera

• Edge detection: Automatic document boundary detection using OpenCV, enhanced by a custom-trained ONNX inference model

• Perspective correction: Manually or automatically adjust document perspective

• Grayscale export: Optional grayscale filter applied during PDF creation

• OCR: Offline text recognition using the open-source Tesseract engine

• PDF export: Save scanned documents as searchable PDFs

• Share & save: Export locally or share via other apps

• Dark mode: System-based Material 3 theme with light and dark appearance

• Privacy-focused: Fully offline — no data leaves your device
