What parents say about our awesome apps: *** 5 stars! Brilliant! An app that understands how kids actually learn. Thank you. *** 5 stars! Every one of your apps that I’ve tried is great! When using “Comprehension Builder”, your learner will first read a passage. The learner must then hold the information in memory in order to answer a multiple choice question. To build sustained attention and working memory, early levels contain 2-sentence texts with limited word count. As comprehension is demonstrated and memory increases, the texts increase in length and difficulty. “Comprehension Builder” contains 200+ fiction and non-fiction texts on a variety of topics. This app is perfect for learners who: - when reading or listening, information seems to ‘go in one ear and out the other.’ - have trouble responding to questions about a text unless they can refer back to the text. - can understand each sentence, but don’t seem to put them together to make meaning from the text as a whole. Additional Features: - Incremental learning. New levels are unlocked only when your child demonstrates mastery. - Fun and engaging Reward Center to increase motivation. - Contains over 600 questions, with content designed by professional teachers and researchers.

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.
