The app allows you to write phrases and listen to them with synthesized voice and view corresponding graphic symbols using the PECS symbol library from SymbolStix.

In PCS mode, you can also build simple phrases by choosing from a few graphical choices displayed at each step. ioParlo also allows you to add custom images to the app by typing a word and pressing "Speak," then touching and holding the word to associate the new image.
