** Winner of prestigious Mom's Choice Award! Featured on Appolicious.com, iHeartThisApp.com ** Inference Ace helps kids who have trouble with reading comprehension. The app builds inference skills step-by-step until mastery. ***** 5 Stars - Nice app for practicing inference. Tons of examples. ***** 5 Stars - My son struggles with comprehension and doesn't like reading long passages. This app teaches a high level of skill in a format he enjoys. Thanks!

With over 450 examples, a fun and engaging reward center to increase motivation, and content designed by professional teachers and researchers, this app is bound to capture the attention of your kids. Best of all, there is detailed reporting for up to 10 students to meet the needs of teachers, therapists and parents. Key Features: - Incremental learning. New levels are unlocked only when your child is ready. - Guided learning for less frustration. Your child will always be guided to the correct answer. - Fun and engaging Reward Center to increase motivation. - Contains over 450 examples, with content designed by professional teachers and researchers. - Inferences are taught from multiple perspectives: what inferences are possible, which are not possible, multiple inferences per sentence, etc. - Our own Smart Sentence technology is used to infinitely vary the examples to prevent learning by rote. - Advanced levels include timers to ensure fluency. Research shows fluency in the foundation skills is critical to reading comprehension. Our apps are designed for and tested by typical and special needs children.

You can try this app by downloading the free version. The free version has 4 free levels for one player. You can purchase levels and players separately through in-app purchases. We are a member of the Moms with Apps program. We collect NO private information in our app, and our apps do not allow unrestricted web access. Inferencing is a key component of reading comprehension. If you can't infer fluently, you can't understand the story. Help your child now by getting started with our Inference Ace app. While you're at it, check out our other apps that target WH questions, identifying inference clues and identifying the main idea of a sentence or paragraph. We take customer service very seriously! If you ever have a problem or find that we've missed something, contact us at our website and we will do our best to fix the problem. ** Note: Inference Ace and Inference Clues intentionally use similar data sets. However, different skills are targeted. Also, when working through this app, you will encounter different variants of the same examples many times as we teach our players to derive multiple inferences from a single sentence -- just like expert readers do. This is an intentional feature, not a bug :-)

SPEAKplay!™ is an evidence-based therapy app to introduce mobile interfaces to prospective users of augmentative and alternative communication (AAC). SPEAKplay! offers a series of gesture-based games that directly target the difficulties in learning complex and multi-step motor skills to access content on mobile AAC devices. The intended outcome of engaging with these games is to enhance motor functioning of the young child or first time AAC user to maximize operational competence in navigating touchscreen-based content. With better gesture and operating skills, children can get started earlier on mobile devices and benefit from AAC applications to the full extent. Training with SPEAKplay! focuses on the critical gestures of (1) Directed and Sustained Touch, (2) Drag and Drop, and (3) Vertical and Horizontal Swipe. The gestures are introduced through a series of fun and engaging games, including “Pop the Bubbles” (for Targeted Touch), “Fly the Rocket” (for Targeted and Sustained Touch), and “Feed the Dino” (for Horizontal and Vertical Swipes as well as Drag and Drop). In the “Pop the Bubbles” game the user is faced with multicolored bubbles that emerge from a bathtub on the bottom. When the bubbles are tapped or “popped” by the user, they disappear from the screen with an auditory “bubble pop” cue. The task for the user is to “pop” all the bubbles till the “You win!” screen appears. To increase the game’s difficulty, the size and number of bubbles available to “pop” can be modified. The “Fly the Rocket” game teaches its users to respond to a visual stimulus, the movements of the stars. The stars either pulse, shake or flash, signaling the user that they need to be touched to fly the rocket through space. With each star that is pressed the rocket moves closer to the moon, and once it reaches the moon the user wins the game. Three levels of difficulty involve four, six, or eight stars to be tapped. Randomization of the sequence in which the stars appear makes the game different each time and unpredictable. The “Feed the Dino” game teaches the user to press and hold onto a dinosaur and move it around to collect food and bones scattered across the screen. To reward and encourage the user to keep playing, the dinosaur dances for a moment as bones are collected before continuing. Once all the food and bones are gathered, the user drags the dinosaur to its home to complete the game and reach the win screen. The game has two modes, one with a free moving dino and one with a path that the dino must follow. This path can be adjusted to be shorter or longer to change the difficulty for completion. SPEAKplay! is a research-based application and complements intervention provided through SPEAKall!® and SPEAKmore!®. The SPEAK application suite has received strong recognition in the AAC industry as documented by prestigious awards including among others: ● 2025 European Academy of Childhood Disability (EACD) Technology & Innovation Award, First Place ● 2018 Anna Kennedy Online Autism Charity, Autism Hero Award – First Place, Entrepreneurial Category ● 2017 Milken Family Foundation Grand Prize and Overall Winner, Milken-Penn GSE Education Business Plan Competition ● 2017 ChanceLight Behavioral Health and Education Prize, Milken-Penn GSE Education Business Plan Competition ● 2017 Edison Innovation Award – Gold, Language Learning Products Thank you for your continued support and please continue to send us your feedback and ideas!
