Four-year-olds occupy an exciting developmental space. They are beginning to recognize letters, count with purpose, understand patterns, and express increasingly complex ideas. They have the fine motor control to interact with touchscreens more precisely than younger toddlers and the attention span to engage with longer activities. This makes four an ideal age to introduce apps that build pre-reading and pre-math skills in preparation for kindergarten. We tested the top contenders with real preschoolers to find the ones that deliver genuine educational value.
How We Evaluated
Each app was tested by four-year-olds over a three-week period, with parents and a preschool educator observing engagement and skill development. We scored on five criteria:
- Kindergarten readiness — Does the app build skills that prepare children for kindergarten (letter sounds, counting, patterns, fine motor)?
- Age-appropriate challenge — Is the difficulty right for four-year-olds, avoiding both boredom and frustration?
- Independent use — Can a four-year-old use the app without constant adult help?
- Safety standards — Is the app free of ads, predatory in-app purchases, and inappropriate content?
- Replay value — Will the child return to the app over weeks and months?

Homer — Best Reading Readiness
Homer (formerly Homer Reading) creates a personalized reading pathway based on your child’s interests and current level. For four-year-olds, this typically means letter recognition, letter sounds, and early blending. The app asks parents to identify their child’s interests — dinosaurs, princesses, trucks, space — and weaves those themes into the reading lessons. This personalization keeps children engaged because they are learning with content they already care about.
The structured lessons follow a proven progression from letter identification through phonemic awareness to early decoding. Between lessons, children access stories that reinforce the skills they are learning. The combination of explicit instruction and applied reading practice is exactly what literacy research recommends.
Why parents love it: Children make visible progress in letter knowledge and phonics within weeks. The interest-based personalization means children ask to use the app rather than resisting it. Progress reports help parents track what their child has mastered.
Limitation: The subscription cost adds up over time, and the app requires consistent daily use to see the best results.
Khan Academy Kids — Best Free Comprehensive Option
Khan Academy Kids covers reading, math, social-emotional learning, and creative expression in a single free app. For four-year-olds, the app offers letter tracing, phonics activities, counting exercises, shape recognition, and storybooks. The adaptive learning path adjusts difficulty based on performance, ensuring each child works at the right level.
The characters are friendly and encouraging, providing voice guidance throughout every activity. The app includes an independent learning section where children can explore freely and a structured path for sequential skill-building.
Why parents love it: It is completely free with no ads, no subscriptions, and no data collection. The breadth of content makes it a one-stop solution for kindergarten readiness.
Limitation: The app covers many subjects but may not go as deep in phonics as a dedicated reading app like Homer or Teach Your Monster to Read.
Teach Your Monster to Read — Best Phonics
Teach Your Monster to Read turns phonics into an adventure game. Children create a monster avatar and journey through levels that teach letter sounds, blending, and early reading. The game follows a systematic phonics approach, introducing sounds in a carefully sequenced order that builds on previous knowledge.
For four-year-olds who are ready for phonics, this app is outstanding. The game mechanics motivate practice, and the phonics instruction is genuinely rigorous. Children learn to hear sounds in words, match sounds to letters, and blend sounds into words.
Why parents love it: The phonics instruction is as good as many classroom programs. Children develop real reading skills, not just letter recognition. The one-time purchase price is excellent value.
Limitation: The game structure means children must progress linearly. If a child struggles with a particular level, they may become frustrated and need adult support to push through.
Moose Math — Best Early Math
Moose Math (from Duck Duck Moose, now part of Khan Academy) teaches counting, addition, subtraction, sorting, and geometry through activities set in a pet shop and juice stand. Children count items to fill orders, sort shapes to build structures, and solve simple addition problems to serve customers.
Why parents love it: The app makes math tangible by connecting numbers to real-world scenarios. Free with no ads. The activities progress in difficulty as children master earlier concepts.
Limitation: The content is finite. A four-year-old who uses the app daily may complete all activities within a couple of months.
Busy Shapes — Best Spatial Reasoning
Busy Shapes challenges children to fit shapes through matching holes, starting simply and adding physics-based complexity. Four-year-olds love the tactile feel of dragging shapes and watching them tumble through. The puzzles build spatial reasoning, problem-solving, and fine motor precision.
Why parents love it: No instructions needed — children figure out each puzzle through experimentation. The gradual difficulty increase keeps it challenging without overwhelming.
Limitation: Narrow focus on spatial skills means this works best alongside a broader learning app.
What to Look For
At four, children are ready for more structured learning than toddlers but still need playful, low-pressure environments. Look for apps that introduce skills through games rather than drills. The best apps for four-year-olds adapt to the child’s level and provide encouragement without excessive rewards that can undermine intrinsic motivation.
Consider what your child needs most. If kindergarten is a year away and letter knowledge is limited, prioritize a phonics app. If math concepts need attention, choose Moose Math. If you want broad coverage, Khan Academy Kids is the best starting point. Many families combine a comprehensive app with one subject-specific app. For more on managing digital habits, see our screen time rules by age.
