Development
Kulatunga, a Sri Lankan computer engineer, wrote a program in Visual Basic for an English–Sinhala dictionary, using the dictionary entries from the English–Sinhalese Dictionary of Gunapala Piyasena Malalasekera. The program was marketed from 23 November 2002. In 2008 he started a free internet version of it, the first online English–Sinhala dictionary. Kulatunga later admitted that he had infringed the copyright of the Malalasekera English–Sinhala dictionary in creating his software, but he said in 2015 that he no longer infringed on copyrights. In 2017 he developed and added Sinhala keyboard input method to his Google Play android app.
