I plan to buy an Android tablet and write a matching pen for the university. I have already seen that there's a wide range of apps for handwritten notes, but for such a system to work for me I have to be able to convert my notes into PDFs, so that I can easily transfer and use them later on PC and laptop. That stood however with none of the relevant Apps thereby as far as I saw that, knows someone which has these functions?
With OneNote that goes as far as I know. All functions require an Office365 subscription. https://www.heise.de/...-app-94144
Squid
The app runs wonderfully on my Galaxy Tab S4 and the S-Pen is also supported.
For the college / school life Squid Premium makes sense. Even without premium run the basic functions such as export, insert images or write with the pen.
