Khan Academy Kids is a free educational app designed primarily for children ages 2–8. Store listings and Khan Academy materials describe its reach, content library, platform ratings, curriculum alignment, and assessment work, while the available figures come from different sources and measurement contexts.

Audience, access, and product position
Khan Academy Kids is positioned for children ages 2–8, according to the Khan Academy Kids app page. The same source describes the app as designed to grow with children from age 2 through 8 and beyond. Khan Academy’s annual report for SY24–25 also describes the program as designed for young learners ages 2–8. These age statements describe the intended audience, not a measured count of children in each age group.
The app page markets Khan Academy Kids as 100% free. It also states that the app has no ads and no subscriptions. Those three claims describe the product’s access and business model as presented by Khan Academy Kids; they are not estimates of household costs, usage, or retention.
The Google Play listing identifies Khan Academy Kids as “Teacher Approved” and presents it for ages 2–8. The Apple App Store classifies it in the Education category, gives it an age rating of 4+, and lists Khan Academy as the developer. The Apple listing identifies English as the app language. The 4+ store age rating and the 2–8 educational audience are different kinds of labels: one is a platform classification, while the other describes the intended learners.
Ratings, reviews, downloads, and platform facts
Store figures provide a snapshot of public platform activity, but they should not be read as a single standardized popularity index. Apple and Google publish separate ratings and review counts, and their figures can change over time.
| Platform or source | Rating or reach figure | Additional listed metric |
|---|---|---|
| Apple App Store | 4.8 rating | 125K ratings |
| Google Play | 4.6 rating | 53.4K reviews |
| Google Play | 5M+ downloads | “Teacher Approved” listing |
| Google Play | More than 21 million students helped | Preschool and elementary students |
| Google Play | More than 180,000 5-star reviews | Listing claim |
The Apple App Store shows a 4.8 rating from 125K ratings. It lists the app size as 207.3 MB. The Google Play listing shows a 4.6 rating from 53.4K reviews and reports 5M+ downloads. The download figure is an open-ended threshold rather than an exact total, and it should not be added to the Apple ratings count or treated as the number of unique children using the app.
Both store descriptions include a much larger reach claim. The Google Play listing says Khan Academy Kids has helped over 21 million preschool and elementary students, while the Apple app page repeats the claim that it has helped over 21 million preschool and elementary students. The wording describes students helped, not necessarily current active users, and the supplied source information does not specify a measurement date for that claim.
The Apple app page reports more than 180,000 5-star reviews, and Google Play gives the same “more than 180,000” figure in its listing. Because this is a listing claim rather than a platform-specific review total in the figures above, it should be kept separate from Apple’s 125K ratings and Google Play’s 53.4K reviews.
The Apple listing identifies the product as a 207.3 MB Education app with an age rating of 4+. These details are useful for understanding the store presentation, but they do not measure educational effectiveness or learning outcomes.
Learning content and developmental coverage
The Google Play listing says children can explore over 5,000 educational games and activities. The Apple app page also says the app contains over 5,000 educational games and activities. Both references describe the same scale claim, so it is counted here once rather than treated as two separate inventories.
The Apple app page says Khan Academy Kids includes hundreds of children’s books and videos. The Khan Academy Kids home page similarly describes hundreds of books, videos, and creative activities, and elsewhere on that page describes thousands of playful activities, books, and videos. These phrases use different quantity bands: “hundreds” applies to the books and videos description, while “thousands” describes the broader collection of playful activities, books, and videos. They should not be combined into a new total.
The app page lists several learning formats and domains: social-emotional learning, math games, reading games, phonics lessons, and interactive storybooks. It also says the app supports preschool, kindergarten, and early elementary learners. Together, these descriptions place the product across early literacy, early mathematics, language-related practice, social-emotional development, and story-based learning.
The Khan Academy Kids home page says the program supports early literacy, reading, writing, language, and math. It also says the program combines academic skill-building with social-emotional growth and creative play. These are descriptions of scope and design, not quantified outcome measurements. No supplied figure establishes that one domain produces a particular improvement or that children complete a specific number of activities.
Curriculum, characters, and learning design
The Khan Academy Kids home page says five whimsical characters guide the experience. The characters are presented as part of the app’s learning design, alongside creative activities and a collection of books and videos. The figure of five refers to the guiding characters, not to the number of instructional pathways or subjects.
The same home page says the app is aligned with the Head Start Early Learning Outcomes Framework and that its curriculum aligns with Common Core. These alignment statements indicate how the curriculum is positioned relative to established educational frameworks. They do not, by themselves, quantify standards coverage, classroom adoption, or student performance.
The home page also says Khan Academy Kids was created in collaboration with learning experts at Stanford. This describes the stated development collaboration. It does not provide a numeric estimate of the number of experts, the duration of the collaboration, or the effect of that work on outcomes.
The Google Play listing says the app offers over 5,000 educational games and activities and is intended for ages 2–8. The Apple app page says the app is designed to grow with children from age 2 through 8 and beyond. Read together, these facts describe a broad early-learning product with a large activity catalog and an age range spanning preschool through early elementary learning.
Product growth and first-grade expansion
The Khan Academy Kids blog says the app launched in 2018. A first-grade lessons post describes a later expansion that added more than 5,700 first-grade-aligned activities, more than 80 animated instructional videos, and 59 new books.
| First-grade expansion item | Quantity reported |
|---|---|
| First-grade-aligned activities | More than 5,700 |
| Animated instructional videos | More than 80 |
| New books | 59 |
The same post says the new books included nonfiction science books from National Geographic and Bellwether Media. It also says the collection included original fiction stories for early readers. The publisher references describe the kinds of books added; they do not establish that every book in the app came from those sources.
The first-grade expansion figures are additions described in that blog post, not a replacement for the app’s broader “over 5,000 educational games and activities” figure. They should therefore not be added together without a defined common inventory and date. The blog’s launch reference places the beginning of the product in 2018, while the expansion figures describe a particular first-grade content update.
Social-emotional learning and assessment research
Khan Academy’s annual report for SY24–25 says Khan Academy Kids added more than 70 new social-emotional lessons. The report says those lessons were created with Harvard professor Dr. Stephanie Jones. The “more than 70” figure describes lessons added in the annual-report period; it does not describe the total number of social-emotional lessons in the app.
The same annual report says the team conducted a second pilot of a Pre-K math and literacy assessment with 300 students. This is a pilot-participant count, not a population estimate and not a claim that 300 students represent all Khan Academy Kids learners.
The Khan Academy Kids PreK assessment page says the tool covers four core domains: math, literacy, receptive language, and executive function. It says there are approximately 56 assessments in total, and that each assessment takes about five minutes. The page also says the assessments are available in English and Spanish.
The assessment page reports that its pilot covered more than 1,000 students, 67 classrooms, and five states. These figures describe the scope of the assessment pilot as presented on that page. They are distinct from the annual report’s second pilot of 300 students; the supplied facts do not establish that the two participant counts refer to the same study, date, or group.
The four-domain structure and approximately 56-assessment count describe the tool’s measurement design. The five-minute duration is a per-assessment estimate, not the time required to complete the full set. Multiplying the figures would create an unsupported total because the page does not say every child completes every assessment or that all assessments take exactly five minutes.
School availability and comparison points
Khan Academy’s districts page says Khan Academy Kids for Schools is available free for publicly funded PreK programs in the 2026–27 and 2027–28 school years. The school-year dates matter: this is a stated availability window, not a permanent-access guarantee or a count of participating programs.
The school offering can be considered alongside the product’s other reported characteristics. The intended learner range is ages 2–8, the app is marketed as free with no ads and no subscriptions, and the educational scope includes early literacy, reading, writing, language, math, social-emotional learning, and creative play. Store listings add platform-specific ratings of 4.8 on Apple and 4.6 on Google Play, while Google Play reports 5M+ downloads.
The available figures answer different questions. Ratings and reviews describe public store feedback; downloads describe a platform threshold; “over 21 million students helped” describes a broad reach claim; content counts describe catalog scale; pilot figures describe research participation; and the 2026–27 and 2027–28 dates describe school-program availability. Keeping those measures separate gives a more accurate statistical picture of Khan Academy Kids than treating them as interchangeable indicators of usage or effectiveness.
