simPODD is an app for the popular PODD system that makes communication more simple for those who can’t speak. Built in collaboration with Gayle Porter, it’s the only PODD app for iPad to bring digital page sets and a printing interface into one app. From the makers of Proloquo2Go, this augmentative and alternative communication (AAC) app is sure to become a favorite among PODD users, because it's the only PODD app built specifically for their needs. “simPODD’s integration of PODD communication books and electronic page sets in a single product supports people to "say what I want to say, to whoever, whenever and however I choose to say it.” - Gayle Porter, creator of the PODD system Highlights • Access to all PODD digital page sets: 15 Preschool, 15+ Preschool, 15 School, 15+ School, 60 Complex Syntax, 60 Expanded Key Word • Fully integrated printing interface in the app to print direct access individual and group PODD books (with yearly subscription) • Streamlined and simplified editing process • Uses SymbolStix • Regionally specific vocabulary and American, British and Australian voices • 38 natural-sounding text-to-speech voices including genuine children’s voices • Free 1-month trial How it works simPODD makes using PODD much simpler. First, it brings the digital page sets and printing experience into one app. No need to manage different payments and subscriptions, or learn how to use multiple programs. It’s all rolled into one. It’s easy to use, no matter who you are: parent, teacher, speech therapist or PODD user. Customizing and editing digital page sets is also very straightforward with simPODD. Quickly edit the vocabulary, create new buttons and link folders without following a lot of complicated steps. Since we worked closely with PODD users while building the app, we took all of the hassle and frustration out of these processes. The easiest PODD book printing experience The printing function for PODD books is right inside the app. Just select a book and customize. Print the book all at once, instead of page by page. It only takes a few minutes! You can create as many books as you need, and print them for all of the people in a PODD communicator’s life. What is PODD? PODD (Pragmatic Organisation Dynamic Display) is a popular AAC system created and owned by Gayle Porter. PODD organizes vocabulary around communication function and predicted likely usage to make it more efficient to get something across. PODD's range of books and page sets support language development from first words to complex syntax. The books and page sets for early communicators also include strategies like pragmatic branch starters. This supports more intelligible and varied communication.
