Software

Shortly after the Newton PDA's release in 1993, developers were not paying much attention to the new Newton OS API and were still more interested in developing for the Macintosh and Windows platforms. It was not until two years later that developers saw a potential market available to them in creating software for Newton OS. Several programs were made by third-party developers, including software to enhance the disappointing hand writing recognition technology of Newton OS 1.x. The basic software that came with Newton OS: *Works — A program for drawing and word processing, with typical capabilities such as: rulers, margins, page breaks, formatting, printing, spell checking and find & replace tools. *
Notes Note, notes, or NOTE may refer to: Music and entertainment * Musical note, a pitched sound (or a symbol for a sound) in music * ''Notes'' (album), a 1987 album by Paul Bley and Paul Motian * ''Notes'', a common (yet unofficial) shortened versio ...
— Used for checklists, as well as both drawing and writing in the same program either with a newton keyboard or a stylus pen. * Dates — Calendar program where you can schedule appointments and other special events. *
Names A name is a term used for identification by an external observer. They can identify a class or category of things, or a single thing, either uniquely, or within a given context. The entity identified by a name is called its referent. A persona ...

s, etc. *Calculator — A basic calculator with square root, percentage, MR, M+ and M- functions additional to the basic functions found on a calculator. *Clock — A small floating window type application, known as a desktop accessory on the Macintosh. The Newton clock also includes features for an alarm, minute timer and the date. *Book Reader — Support for displaying electronic books is built in.

. The earliest versions had weaknesses that resulted in bad publicity and reviews. However, with the release of Newton PDAs based upon version 2.0 of the OS, the handwriting recognition substantially improved, partially being a product of ParaGraph and an Apple-created recognizer pair: Apple's Rosetta and Mondello. Newton's handwriting recognition, particularly the print recognizer, has been considered by many reviewers, testers, and users to be the best in the industry, even 10 years after it was introduced. It was developed by
