This thread is super old, but I think this is still a relevant issue. I tried @kellerjustin's app. As it uses Tesseract OCR, it can read typeface really well. However, the ability to read handwriting is lacking a bit. The OCR built-in to the Rocketbook app is excellent for handwriting, so it would be advantageous to be able to get the generated text into Joplin easily. The Rocketbook built-in Evernote integration works well and would be a great feature to mimic.
