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 :-)

The developer of the only clinically-validated language therapy application MITA that was downloaded by over 3 million families, brings you a series of Speech Therapy apps: Speech Therapy Step 1 – Preverbal exercises Speech Therapy Step 2 – Learn to sequence sounds Speech Therapy Step 3 – Learn to say 500+ words Speech Therapy Step 4 – Learn to say complex words Speech Therapy Step 5 – Record your own model words and exercise articulation Speech Therapy Step 4 is for children who already learned many words and want to exercise on their articulation. HOW IT WORKS? Speech Therapy Step 4 uses 1000+ prerecorded video exercises. These videos encourage children to mirror words’ pronunciation. A proprietary AI algorithm measures similarity between model words and children’s vocalizations. Improvements are rewarded with reinforcers and PlayTime. This technique was demonstrated to improve speech production in toddlers, late talkers (speech delay), children with Apraxia of Speech, Stuttering, Autism, ADHD, Down Syndrome, Sensory Processing Disorder, Dysarthria. Video exercises are followed by a PlayTime. Improvements in performance are rewarded with reinforcers and a longer PlayTime. In order to achieve a longer PlayTime, children try to improve their articulation. In this way the app works autonomously all the time encouraging children to improve articulation. LEARN WITH SPEECH THERAPY STEP 4 - The only speech therapy app that rewards your child proportionally to the improvement of their articulation. - Uses scientifically proven video modeling for effective speech development. - Voice-activated functionality provides a fun, interactive learning experience. - The app basic version is completely FREE! - No ads. SCIENTIFICALLY-PROVEN LEARNING TECHNIQUES Speech Therapy Step 4 uses video modeling to create an immersive learning environment. When children watch model videos in real time, their MIRROR NEURONS are engaged. This is scientifically proven to be highly effective in speech development. FROM THE DEVELOPERS OF THE CLINICALLY-VALIDATED LANGUAGE THERAPY APPLICATION MITA Speech Therapy Step 4 is developed by Dr. A. Vyshedskiy, a neuroscientist from Boston University; R. Dunn, a Harvard-educated early-child-development specialist; MIT-educated, J. Elgart and a group of award-winning artists and developers working alongside experienced therapists.
