Best Apps for Kids to Learn Science in 2026: 7 Apps Compared

Khan Academy Kids is our pick for younger children because it removes every barrier that usually worries parents. It is free, has no ads and no in-app purchases, and its science content sits alongside reading, math and social-emotional learning in one friendly app. Animated characters guide children through books, videos and activities, and offline mode helps on trips and in cars.

The limit is age. Children near the top of the 2 to 8 range will outgrow the difficulty quickly and need to move to the main Khan Academy app or a subject-specific tool. For preschool and early elementary science basics, though, Khan Academy Kids is the safest and simplest start.

Tappity feels like a science teacher in an app. A real teacher leads lessons across topics like animals, space, weather and the human body, and children follow along with hands-on activities they can try at home. The science journal lets kids record discoveries and experiment results, which builds the habit of observing and noting, not just watching.

Access is mainly iOS and web, so Android families should check current availability. A subscription gives access to the full lesson library, while a trial lets you test whether your child engages with the teacher-led style. For elementary kids who ask why about everything, Tappity turns that curiosity into structured learning.

PBS Kids Games brings science play to preschoolers through characters they already know. Games cover topics like animal habitats, weather, plants and simple machines, wrapped in short, friendly activities that suit young attention spans. As a nonprofit product, it avoids the advertising and purchase pressure found in many free kids apps.

Depth is limited by design. These are short games, not a curriculum, and elementary children will want more challenge soon. For ages 2 to 8, especially for a first science app, PBS Kids Games is a safe, free and genuinely enjoyable choice.

ABCmouse offers the most structured early learning path on this list, with ten levels that move from basic concepts to more complex ones. Science appears alongside reading, math, art and music, so a child who loves science also builds surrounding skills. Parents can track progress and see which activities their child has completed.

The subscription is the main drawback, and the reward-heavy design can distract some children from the learning itself. A free trial helps you judge whether the structure suits your child. For families who want a guided curriculum rather than a loose collection of games, ABCmouse is a strong option.

Lingokids takes a play-first approach to learning, with games, songs and shows that cover science alongside literacy, math, art and music. The ad-free design and kidSAFE certification reassure parents, and up to four child profiles make it practical for siblings. Offline play helps on the go.

Science is part of a broad curriculum, not a dedicated science app, so children who want deep science exploration will need a second tool. For younger kids who learn best through play and who enjoy variety, Lingokids is a cheerful and safe choice.

PhET Interactive Simulations, from the University of Colorado, lets children and teens experiment with science rather than just reading about it. Build circuits, mix chemicals, explore gravity and test how atoms behave, all in a safe virtual lab. The simulations are research-based and free, which makes PhET a favorite in classrooms worldwide.

Younger children may need a parent or teacher to guide them, since the simulations assume some reading and reasoning. For upper elementary kids, middle schoolers and teens, PhET is the closest thing to a real lab without the cost or safety concerns, and it pairs well with school science topics.

BrainPOP Jr. explains science through short animated movies that make tricky ideas feel simple. Topics cover animals, space, weather, the human body and more, with quizzes and activities to check understanding. The tone is friendly and the explanations are clear, which suits younger elementary children who learn by watching and listening.

It is less hands-on than PhET or Tappity, since children watch and answer rather than experiment. A subscription gives access to the full library, though a trial shows whether the style clicks. For a child who loves to ask how things work and enjoys animated explanations, BrainPOP Jr. is a reliable pick.
