Several months ago, I mentioned a handwriting app named Note Anytime.
Afterward, I installed another app named Penultimate.
Having used both of them for some time, I feel Note Anytime is superior to Penultimate, though the latter is convenient to synchronize Evernote.
To give a few reasons, its "calligraphy pen" is beautiful, lasso tool is more useful, and "wrist guard" function is much better.
