Readability’s award-winning Smart Reading & Comprehension Learning App gives your child the effectiveness of 1-on-1 tutoring. Our breakthrough voice-based technology LISTENS while your child READS, highlighting, and correcting any problem words. Kids from kindergarten to 6th grade will improve their reading, vocabulary, and comprehension skills all in the convenience of a mobile app. IMPROVE READING WITH 1-ON-1 TUTORING Readability prompts your child to read aloud and listens while providing reading help and real-time pronunciation correction as your child reads. If they get stuck, they can tap on the speaker icon to have Readability read the selected passage or word aloud. Readability automatically selects the right reading material for each child to maximize improvement and minimize the reading struggle. Your child will be eager to learn as these fun and educational grade-level stories come to life with bright illustrations. IMPROVE CRITICAL THINKING SKILLS Our industry-first comprehension with Interactive Voice-based Questions & Answers (IVQA™) asks your child questions verbally about the story they just read to improve their critical thinking skills. Your child then is prompted to answer the question verbally to ensure they fully understand what they read. Comprehension is as important as reading fluency, we deliver both in our smart reading app for kids. IMPROVE VOCABULARY Readability makes it easy to learn new words and their meaning with a personalized vocabulary list for your child. Your child can long-press on any word while reading to learn its pronunciation, meaning, and add it to their vocabulary list. Their vocabulary list is neatly organized A-Z and by book to further practice, review, and perfect new or difficult words. SET AND TRACK READING GOALS Set goals and follow your child’s progress with your very own Parent Dashboard detailing what they have read, reading duration, accuracy, comprehension, and speed. It also provides daily and weekly reading reports for accountability that can be shared with a teacher.
