OCR apps that actually get it done?

Yes - the regular Google Play and F-Droid versions are currently identical. The PaddleOCR variant is experimental for now and only published on GitHub mainly because of the significantly larger APK size (models are included for fully offline use. MakeACopy will always remain offline-first). It is still fully open source. I extended the existing ONNX Runtime build script, which is already used for the standard version as well.
