Jellow Plus is also an extension of Jellow Basic. It has all the icons and much more in this version. The expressive buttons, which were part of the Emotional Language Protocol (ELP) driving Jellow Basic, are available in Jellow Plus. These features make it easy for children using Jellow Basic to graduate to Jellow Plus as they grow up, making it possible to communicate better.

Jellow’s library of icons can help adults communicate using pictures along with their corresponding word labels.
