[1][2] The device was designed by the Simputer Trust, a non-profit organization formed in November 1999 by seven Indian scientists and engineers led by Dr. Swami Manohar.

Similar in appearance to the PalmPilot class of handheld computers, the touch sensitive screen is operated on with a stylus; simple handwriting recognition software is provided by the program Tapatap.

Software packages include: Scheduling, Calendar, Voice Recording and Playback, simple spreadsheet application, Internet and network connectivity, Web browsing and email, an e-Library, games, and support for Java ME, DotGNU (a free software implementation of .NET), and Flash.

In 2005, they were used in a variety of applications, such as automobile engine diagnostics (Mahindra & Mahindra in Mumbai), tracking of iron-ore movement from mine pithead to shipping point (Dempo, Goa), Microcredit (Sanghamitra, Mysore), Electronic Money Transfer between UK and Ghana (XK8 Systems, UK), and others.
