ABCmouse vs. Khan Academy Kids vs. Duolingo: We Downloaded 11 Apps and Let Our Kids Decide

Screen time is one of those parenting conversations that never really ends. You want the time to count for something. You want your five-year-old's forty-five minutes with a tablet to look more like learning and less like passive consumption. And so you download an app, or four, and you hope.

I started this project because I was already paying for two educational apps and had no real idea whether either of them was working. My kids would pick them up, play for a bit, then drift back to YouTube. I wanted to know: are any of these apps genuinely good at teaching kids? Which ones do children actually choose when they have options? And is the free tier ever actually enough?

Over six weeks, I downloaded and tested eleven apps with four children across two families. The kids ranged from age two to eight. We tracked engagement, learning progress, how long kids stayed on each app without prompting, and parent observations on what, if anything, stuck. I also consulted with a former elementary school teacher who reviewed the curriculum structure of each top contender.

What We Evaluated

Not all "educational" apps earn the label. Some are candy-colored distraction machines with a thin academic veneer. We judged each app on six criteria:

• Learning outcomes: Does the curriculum actually align with what kids need to know? Is there clear progression?
• Engagement and fun: Do kids choose to come back? Do they stay engaged without parental nudging?
• Ad-free experience: We will not recommend an app that interrupts learning with advertising to children.
• Subscription cost: What does it actually cost? Is the free version meaningful or a demo?
• Age range and differentiation: Does the app genuinely work across the 2 to 8 age span?
• Teacher approval: Would an educator recommend this as a learning supplement?

Here is what we found, ranked from best to least recommended.

Khan Academy Kids

"The only app where kids asked to keep going after screen time ended."

Khan Academy Kids is free. Completely free. No subscription, no premium tier, no upsell. The nonprofit behind it built this specifically as a public good, and it shows in every design decision. There are no ads. No in-app purchases. No dark patterns nudging kids toward content that is not there. Just a genuinely excellent curriculum-aligned app for children ages two through eight.

The app covers reading, writing, math, logic, and social-emotional learning. The curriculum is built in partnership with learning experts and aligns with what educators actually want kids to know before kindergarten and through early elementary. The characters are warm, the pacing is patient, and the feedback loops are encouraging without being hollow.

In our testing, this was the one app where children across multiple age groups voluntarily extended their sessions. Our three-year-old would start a reading activity and still be at it twelve minutes later. Our seven-year-old worked through a math sequence for twenty-five minutes on a Saturday morning without being asked. That does not happen with every app.

The teacher we consulted flagged it immediately: "This is what I recommend to every parent who asks me about apps. The curriculum is serious, the execution is excellent, and the price is right. There is nothing else like it."

ABCmouse

"Broad curriculum, high production value, and a subscription cost that adds up."

ABCmouse is one of the most recognized names in children's educational apps, and for good reason. The scope is impressive: over 10,000 activities spanning reading, math, science, art, and music for children ages 2 through 8. The visual production is high-quality, the reward systems are well-designed, and the learning path is structured in a way parents can follow easily.

The curriculum is solid. Our educator reviewer noted that it covers early phonics well and the math progression is logical. Kids in our test responded positively, particularly to the arts-and-music content and the classroom framing that younger children found engaging.

The honest caveat is the cost. At $12.99 per month (or roughly $60 per year on an annual plan), ABCmouse is not cheap for a family already stretched on subscriptions. And when we placed it alongside Khan Academy Kids in the same testing environment, the free app held its own on every learning metric that mattered. ABCmouse is genuinely good. It just faces an uncomfortable comparison at zero dollars.

Duolingo for Kids

"The best option if language learning is the goal. Narrow focus by design."

Duolingo's children's offering focuses narrowly on language learning, and it does that job very well. The app is designed for early readers with simple mechanics, colorful characters, and the same streak-and-reward system the adult Duolingo uses. For families who want to introduce a second language early, it remains the easiest-to-use option on the market.

The free tier is functional, with Duolingo Super (around $6.99/month) removing ads and unlocking offline access. The ads on the free tier are not shown to children during active lessons, which is a meaningful design choice worth noting.

The limitation is scope. Duolingo for Kids does not cover math, reading in the sense of phonics or literacy, science, or any other curriculum domain. It is a language app. If your child is monolingual and you want broad early-learning coverage, this is not the right tool. If you want your four-year-old to start picking up Spanish, it is excellent.

Starfall Education

"A reliable phonics-first option that shows its age in places."

Starfall has been around since 2002, and its reputation as a phonics resource for early readers is well-earned. The core reading content, particularly the ABCs and early phonics sequences, is pedagogically sound and has been used by teachers as a classroom supplement for years. The app version keeps that DNA intact.

The free website version remains functional, and the paid membership at around $35 per year adds a broader set of math and reading activities. Our children responded well to the reading content but found the visual design noticeably less polished than Khan Academy Kids or ABCmouse. The two-year-olds in our group showed little interest; the five-to-seven-year-olds working on early reading engaged meaningfully.

If your child is specifically in the early phonics stage and you want a teacher-trusted tool, Starfall earns its place. As a general educational app for a range of ages, it feels narrow.

Reading Eggs

"Solid reading-focused app that sits awkwardly on price."

Reading Eggs is a reading-focused app designed for ages 2 to 13, with a structured program for early readers and a separate Reading Eggspress component for older children working on comprehension. The core mechanics are well-built, the phonics progression is systematic, and the parent dashboard is among the better ones we looked at for tracking progress.

The challenge is positioning. At $9.99 per month or $69.99 per year, Reading Eggs is priced as a premium product in a category where Khan Academy Kids offers a comparable reading experience for free. It is a good app. It is not a clear better choice for most families at that price.

The sweet spot for Reading Eggs is families with children in the 5 to 8 range who are actively working on reading fluency and want the structured progression and parent reporting the app provides. For toddlers or as a general-learning tool, there are better options at lower cost.

Homer Learn & Grow

"The best premium option. Personalized, beautiful, and genuinely effective for early readers."

Homer's distinguishing feature is personalization. When you set up a child's profile, the app asks about their interests, learning level, and current skills. The curriculum then adapts around those inputs, delivering reading and math content wrapped in themes the child actually cares about. A child who loves dinosaurs gets reading activities about dinosaurs. It sounds simple, and it is, but the execution is excellent.

In our testing, Homer produced the highest sustained engagement of any paid app we looked at. The five-year-old in our group who was the most resistant to structured learning spent 18 uninterrupted minutes on Homer in our first session, then asked to go back the next day. The personalization matters.

Homer is positioned primarily for ages 2 through 8 and covers reading, writing, math, and creative thinking. At $9.99 per month or $59.99 per year, it sits at a similar price to Reading Eggs. The difference is breadth and engagement quality. If you are going to pay for an educational app, Homer is the one we would recommend. The only reason it is not our overall winner is that Khan Academy Kids is free and nearly as good on learning outcomes.

Side-by-Side Comparison

Final Verdict

The honest conclusion of six weeks of testing is simpler than the parenting-app category wants it to be: download Khan Academy Kids. It is free, it is excellent, and it performs at or above the level of paid alternatives on every metric that matters for learning. There is no reason for most families to be paying $60 to $80 per year for a children's educational app when this exists.

The case for spending money is narrow but real. If your goal is specifically second-language acquisition, Duolingo for Kids is the right tool and worth the subscription. If your child is a resistant learner who needs personalization to stay engaged, Homer's interest-based approach may unlock engagement that the free alternative cannot. If you are raising a bilingual household and want structured language learning alongside a general curriculum, the combination of Khan Academy Kids and Duolingo covers almost everything.

What we found most consistently across the apps we tested is that engagement predicts learning far more than curriculum design does. A child who stays on Khan Academy Kids for twenty minutes is learning more than a child who spends five minutes on an expensive premium app before losing interest. Start with free. See what your child actually uses. Go from there.
