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.

Verdict

The call

The clearest difference is review sentiment: Astral Tutor at 100% against Readability's 56%. Astral Tutor also leads on in-app purchases (none vs 2). Readability's advantage is rating (4.6 vs 4.0) and ratings volume (25K vs 4). On price, update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Readability holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Readability has 25K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 56% of Readability's written reviews are positive against 100% of Astral Tutor's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Readability ships an update fortnightly, Astral Tutor daily. The most recent releases landed on November 4, 2026 and October 14, 2026 respectively.
