Notational Velocity is a computer program for Mac OS X used for notetaking. It allows users to create notes using solely a computer keyboard and search them using incremental find. Other features include database encryption, basic text formatting, tags and spellcheck.{{cite web|url=http://lifehacker.com/5815743/the-best-syncing-note+taker-for-mac|last=Dachis|first=Adam|publisher=Lifehacker|accessdate=2012-01-11|date=2011-06-27|title=The Best Syncing Note-Taker for Mac}}. In addition, users can synchronize notes with Simplenote and export to a variety of formats, including plain text, HTML and rich text. It has been recommended along with Simplenote as a solution for taking and syncing notes by both Wired and Lifehacker.{{cite news|last=Sorrel|first=Charlie|title=Simplenote and Notational Velocity Bring Document Syncing to iPad|url=https://www.wired.com/gadgetlab/2010/04/simplenote-and-notational-velocity-bring-document-syncing-to-ipad/|work=Wired|accessdate=11 January 2012|date=27 April 2010}}
