i use this for my Kindle (the tablet kind), just for small things, but iv started using it to read pdfs and would appreciate the added feature of swiping to the next page or slide when not in note taking mode. i don't know if this is a feature already or not, but iv given it a good look. I hope this gets added cuz I really quite like it other wise :)

This app is the best of the best if you're looking for a 3rd party noting app. I've been using it on my phone with a disc pen so I haven't tried it out with my tab but im pretty sure it will be even better (im not sure if it has palm rejection support on S-Pen or Apple Pencil etc.) But overall my favorite feature is creating notebooks, which helped me with organisaton.

Best Note Taking App out there. I use it with my table for documentation of inspections (on the go) and also for protocoling meetings. It just completely replaces the need for paper. Additional features like inserting image etc. are just great. Currently, it just defines my work a d could not go without it. Only missing feature but currently no real need (nice to have): synchronization of multiple devices or access over pc/browser.
