Wemogee is described as 'Through the translation of text to emoji and vice versa, Wemogee allows people affected with Aphasia to communicate only through images'. There are three alternatives to Wemogee for a variety of platforms, including Android, iPad, iPhone, Linux and Mac. The best alternative is AACSpeechBuddy, which is free. Other great apps like Wemogee are LetMeTalk (Freemium) and Free Speech (Free, Open Source).
Free Speech allows users (and/or their caregivers) to create and edit their own personal boards using their device itself. Boards consist of one or more tabs. Tabs contain one or more buttons. Each button can speak a word or phrase.
