The applications for creating notes are mass, but few of them support the possibility of handwriting, which for many of us is still the fastest and most intuitive.
Penultimate is created by the company that gave the world Evernote and made an application with not less love and attention. You can draw, write notes in multi-colored ink, choose one of the suggested substrates as background or upload your own. There is protection from accidental finger or wrist touches, there is also a convenient search.
It is obvious that the program is adapted to work with the stylus and has synchronization with Evernote.
