IMPORTANT NOTE: THIS IS NOT A SUBSCRIPTION! AFTER THE 30 DAYS, IT JUST STOPS WORKING. You don't have to cancel it...YOU AREN'T GOING TO BE CHARGED. If Speak for Yourself is the right choice, purchase the full version! It’s FINALLY here! This is the answer to everyone who has been hesitant to purchase the full version of Speak for Yourself without being able to try it. SFY-Lite 2.0 (and above) gives you access to the full Speak for Yourself app capabilities* for a 30 day FREE trial!  SfY-Lite includes access to the almost 5000 word vocabulary, full programming capabilities, the unparalleled search feature, history feature, Hold That Thought, and voice options. By doing this, AAC users, SLPs, other professionals, and family members are able to use the intuitive programming and features of Speak for Yourself and access the library of almost 11,000 Smarty Symbols®. SFY-Lite is not intended to be an individual's permanent AAC language system. It was designed to determine if an individual is able to access the button size, activate the buttons, and use Speak for Yourself to improve communication.  The free trial will only last for 30 days. After the 30 days, it will go back to the static main screen where it started. HOWEVER, you will be able to access your history data and your vocabulary file, even after the trial ends. That means that any of your programming and customization will be saved so that you can transfer it into the full version. Speak for Yourself was designed by two ASHA-certified speech-language pathologists (SLPs) with an extensive knowledge of AAC devices and implementation. We're very excited to give EVERYONE the ability to have the full functionality of Speak for Yourself in their hands and homes for free! You have nothing to lose and every reason to take 30 days and give it a try. With the release of a new and improved SFY-Lite, we invite you to join us in our mission to change the world...one voice at a time. *The only features that are not available in SfY-Lite are Acapela premium voice offered in the full version as in-app purchases and multi-user capabilities (the full version can hold 40 different user vocabulary files).

Verdict

The call

The clearest difference is update cadence: Fast AAC at every 3 days against SFY's every 52 months. Fast AAC also leads on review sentiment (80% vs 58%) and rating (4.4 vs 4.2). SFY's advantage is ratings volume (150 vs 8) and iOS requirement (15.6 vs 17). On price, ads, in-app purchases and monetization model there is nothing between them.
