The kids section of the Play Store is a minefield. For every genuinely good preschool app there are ten that bury junk ads between activities, push a subscription on a three-year-old, or quietly hoover up data. So we did the boring part for you: we installed the popular pre-K learning apps on Android, watched what they do to a child mid-activity, and kept only the ones that are safe to hand over. The American Academy of Pediatrics is clear that for this age the thing that matters most is the quality of what is on screen, not just the minutes. Every app here is chosen on that basis. One change since you may have last looked: Noggin, a longtime favorite, is gone in the form parents knew, so it is off the list.

Pick the app that fits your child
The pre-K learning apps at a glance
| App | Best for | Ages | Price | Ads | In-app buys |
|---|---|---|---|---|---|
| Khan Academy Kids | The safe free default | 2 to 8 | Free | None | None |
| Endless Alphabet | Vocabulary and letters | 3 to 5 | One-time unlock | None | One unlock |
| ABCmouse | A full curriculum | 2 to 8 | Subscription | None | Subscription |
| Talented and Gifted | Worksheet-style practice | 2 to 10 | Subscription | None | Subscription |
| Lingokids | Playful all-rounder | 2 to 8 | Freemium | None | Subscription |
| Duolingo ABC | Early reading and phonics | 3 to 8 | Free | None | None |
| PBS KIDS Games | Familiar characters | 2 to 5 | Free | None | None |
| Montessori Preschool | Montessori method | 3 to 7 | Freemium | None | Subscription |
| Moose Math | Early numbers | 2 to 5 | Free | None | None |
The honest split is free versus paid. Four of these apps cost nothing and carry no ads, which is rare and worth starting with. The paid ones buy you a structured curriculum and progress tracking. None of the nine show third-party ads to your child, which was our first cut. If your child is ready for more, our roundup of educational games for children and our wider list of Android education apps pick up where this one leaves off.
How we chose
A pre-K app earns trust before it earns a spot. We installed each one, made a child profile, and ran through real activities looking for what actually goes wrong with kids apps. The bar:
- No third-party ads. No banner or video ad network selling to a preschooler between activities.
- No purchase traps. Any in-app purchase or subscription sits behind a parental gate, not one tap from a child’s finger.
- Real learning, not just play. The app teaches letters, numbers, or early skills, with some structure behind it.
- Age-appropriate and private. Content fits ages two to five, and the app does not sell or leak a child’s data.
We also looked for Google Play’s Teacher Approved badge, which means teachers reviewed the app for the youngest age it targets. Treat it as a floor, not proof an app will teach your child anything, but it is a useful signal that the basics are handled.
1. Khan Academy Kids
If you install one app, install this one. Khan Academy Kids is completely free, with no ads and nothing to buy, ever. That is almost unheard of for an app this good. It covers letters, numbers, reading, drawing, and social-emotional skills for ages two to eight, wrapped in a friendly world of characters that keeps young kids moving without bribing them.
It is free because Khan Academy is a nonprofit, not because it is selling your child. The app was built by the team behind Duck Duck Moose, a much-awarded kids studio Khan brought in-house, which is why it feels so polished. There is genuinely no catch here, which is exactly why it leads this list.
Highlights
⭐️ Best for: any pre-K family, and anyone who wants one free app that does it all
⚠️ The catch: the library is broad, so younger toddlers may need you to steer them at first
💰 Pricing: free forever, no ads, no in-app purchases
Key features
- Truly free: no ads, no subscription, no in-app purchases, run by a nonprofit.
- Broad curriculum: reading, math, drawing, and social-emotional learning in one app.
- Offline friendly: activities work without a constant connection.
- Built by a serious team: made by the award-winning Duck Duck Moose studio inside Khan Academy.
2. Endless Alphabet
Endless Alphabet is the one that makes vocabulary stick. Friendly little monsters act out each word while the letters wiggle into place, so a child learns what “gargle” means as well as how to spell it. It is calm, ad-free, and beautifully made, and it is a favorite for a reason.
Worth knowing before you tap install: it is not a free app in the usual sense. The download includes a handful of words, and the full set unlocks with a single one-time purchase, or comes included if you have Google Play Pass. There is no recurring subscription, which makes it one of the cheaper picks here over time.
Highlights
⭐️ Best for: building early vocabulary and letter recognition without ads
⚠️ The catch: the free download is a sample; the full word set is a one-time unlock
💰 Pricing: one-time in-app purchase to unlock everything, or free via Play Pass
Key features
- Vocabulary first: teaches word meaning, not just spelling, with playful animations.
- Ad-free and calm: no ad network, no flashing upsells mid-activity.
- One-time cost: a single unlock, no subscription clock running.
- Polished design: from Originator, a studio that specializes in early learning.
3. ABCmouse
ABCmouse is the closest thing to a full preschool curriculum on your tablet. It runs a structured path of reading, math, art, and science across hundreds of lessons, with a reward system that keeps kids coming back. For a parent who wants a guided program rather than a grab-bag of games, it is the most complete option here, and there are no third-party ads.
Here is the part the glossy reviews skip. ABCmouse is a subscription, and its maker, Age of Learning, settled a Federal Trade Commission case over making memberships auto-renew and hard to cancel. The app is good and the content is safe; just set a reminder before the trial ends and cancel through your account, not by deleting the app. Pricing runs around fifteen dollars a month, often discounted heavily for the first year.
Highlights
⭐️ Best for: parents who want a structured, level-by-level curriculum
⚠️ The catch: it is a subscription, and the company settled an FTC case over hard-to-cancel auto-renewals
💰 Pricing: monthly subscription, around fifteen dollars a month with a first-year discount; free trial
Key features
- Full curriculum: a structured path across reading, math, art, and science.
- No third-party ads: the content itself is clean and age-appropriate.
- Progress tracking: a step-by-step level system you can follow.
- Cancel with care: turn off auto-renew in your account; the FTC fined the company over this exact friction.
4. Talented and Gifted
Talented and Gifted, from Kids Academy, leans academic. It is heavy on worksheet-style practice, tracing, and structured tasks across reading and math, with progress reports for parents who like to see the numbers. If your child responds well to clear, repeatable practice, it delivers, and there are no ad networks in it.
Two honest notes. It is a subscription, and the priciest monthly option here, so it only makes sense if your child will use it regularly. And the marketing leans hard on “gifted” and elite-school language; Common Sense Media flagged that framing and some rough edges. Treat it as solid structured practice, not a fast track to anything.
Highlights
⭐️ Best for: kids who like worksheet-style, repeatable academic practice
⚠️ The catch: it is a subscription and the dearest monthly pick; the gifted marketing oversells it
💰 Pricing: monthly subscription, around twenty dollars a month after a short trial
Key features
- Structured practice: tracing, worksheets, and step-by-step reading and math tasks.
- Parent reports: progress tracking for families who want the detail.
- No ad networks: the activities themselves are ad-free.
- Set expectations: good drill practice, not the Ivy League head start the ads imply.
5. Lingokids
Lingokids is the playful all-rounder. It wraps reading, math, science, music, and life skills in cartoon adventures that feel more like a show than a worksheet, which is exactly why some kids who resist other apps stick with this one. It is ad-free, has no random in-app purchases aimed at kids, and carries a kidSAFE certification.
It is freemium: a limited free tier exists, but the full thing is a subscription of around fifteen dollars a month. It also works offline, which is genuinely useful for car trips and flights. Good Housekeeping has named it a best educational app more than once, and it earns the place on this list.
Highlights
⭐️ Best for: kids who learn best through playful, story-driven activities
⚠️ The catch: the free tier is limited; the full experience is a subscription
💰 Pricing: freemium, with a full subscription around fifteen dollars a month
Key features
- Play-first design: cartoon adventures across reading, math, science, and life skills.
- Ad-free and certified: no ads, kidSAFE certified, purchases behind a parent gate.
- Works offline: download activities for trips.
- Award-winning: a repeat best-educational-app pick at Good Housekeeping.
6. Duolingo ABC
From the people behind the green owl, Duolingo ABC is a free, focused early-reading app. It teaches letters, sounds, and first words in short, friendly lessons that build on each other, the same bite-sized approach that made Duolingo famous, aimed at three to eight year olds learning to read.
The headline is that it is completely free, with no ads, from a company that funds it through its main language app. If your child is at the cusp of reading, it is the cleanest free phonics companion you can install, and it pairs naturally with a broader app like Khan Academy Kids.
Highlights
⭐️ Best for: a free, structured path into phonics and early reading
⚠️ The catch: it is reading-focused, so you will want a broader app alongside it
💰 Pricing: completely free, no ads
Key features
- Free, no ads: funded by Duolingo’s main app, not by selling to kids.
- Reading focus: letters, sounds, and first words in a clear sequence.
- Bite-sized lessons: short sessions that suit a young attention span.
- Trusted maker: built by Duolingo, with the same lesson design.
7. PBS KIDS Games
If your child already loves Daniel Tiger or the characters from Sesame Street and Wild Kratts, PBS KIDS Games turns that affection into learning. It is a free collection of dozens of games built around public-television shows, covering early math, literacy, science, and problem-solving, and it is ad-free and works offline.
Note the name: this is PBS KIDS Games, the play-and-learn app, not the PBS KIDS Video app, which is passive streaming. For a preschooler you want the games. It is a strong, no-cost way to use characters your child already trusts, from a source parents already trust.
Highlights
⭐️ Best for: kids who love PBS characters and learn by playing
⚠️ The catch: it is a games grab-bag rather than a single structured path
💰 Pricing: completely free, no ads
Key features
- Free and ad-free: public-media funded, no ad networks.
- Familiar characters: games built on shows kids already know and trust.
- Broad skills: early math, literacy, science, and problem-solving.
- Works offline: download games for time away from wifi.
8. Montessori Preschool
If you like the Montessori approach, this app from Edoki Academy brings it to the tablet thoughtfully. Children move through practical-life activities, phonics, numbers, and geography at their own pace, in the calm, uncluttered style Montessori is known for. It is ad-free and designed with actual Montessori educators.
It is freemium, with the full library on a modest subscription of around seven dollars a month, and it is included with Google Play Pass if you have it. For a child-led, low-stimulation alternative to the busier apps here, it is the standout.
Highlights
⭐️ Best for: families who want a calm, child-led Montessori approach
⚠️ The catch: the full library needs a subscription, though a cheaper one than most
💰 Pricing: freemium, full access around seven dollars a month or via Play Pass
Key features
- Montessori method: self-paced, practical-life and phonics activities by real educators.
- Calm by design: low-stimulation, uncluttered screens.
- Ad-free: no ad networks, purchases behind a parent gate.
- Affordable: one of the cheaper subscriptions, and free on Play Pass.
9. Moose Math
Moose Math, from the same Duck Duck Moose team behind Khan Academy Kids, is a free, focused way into early numbers. Children run a smoothie shop, play bingo, and build a city while practicing counting, addition, sorting, and shapes, with a report card that maps to early-math standards.
It is completely free, with no ads and nothing to buy, which makes it an easy companion to a broader app when you want to shore up numbers specifically. It is older and simpler than some picks here, but for free, ad-free early math, it still holds up.
Highlights
⭐️ Best for: free, ad-free practice with counting and early math
⚠️ The catch: it is numbers-focused and a bit older in style
💰 Pricing: completely free, no ads, no purchases
Key features
- Free, no ads: nothing to buy, from a trusted kids studio.
- Numbers focus: counting, addition, sorting, and shapes through play.
- Standards-aligned: a report card mapped to early-math goals.
- Same makers as Khan Kids: Duck Duck Moose quality.
Keeping it safe, and keeping it short
What we screened out: any pre-K app with third-party behavioral ads, in-app purchases a child can reach without a parent gate, dark-pattern subscription funnels, or a history of selling children’s data. Several popular apps did not make the cut for exactly these reasons.
Picking a safe app is half the job. The other half is how it is used. Common Sense Media’s research has found children under eight already average more than 2 hours of screen media a day, so what fills that time matters. The American Academy of Pediatrics suggests about an hour a day of high-quality programming for ages two to five, and, more importantly, that you watch or play along when you can. Co-using an app turns screen time into shared time, and it is the single biggest thing that makes any of these apps work. For hard limits on the device itself, pair your pick with a good parental control app.
The verdict
Start with Khan Academy Kids. It is free, it is genuinely ad-free, it covers the most ground, and there is nothing to cancel later. Add Duolingo ABC for reading and Moose Math for numbers, both free, and most families are set without spending a cent. If you want a guided curriculum and do not mind paying, ABCmouse and Lingokids are the two to consider, with the reminder to cancel ABCmouse through your account rather than by deleting the app. Whatever you choose, the best results come from sitting down next to your child for part of it.
What parents usually ask
- Which of these apps are completely free?
Khan Academy Kids, Duolingo ABC, PBS KIDS Games, and Moose Math are fully free with no ads and nothing to buy. They are the best place to start. - Are these apps really ad-free?
None of the nine show third-party ads to your child. That was our first cut. The paid apps make money from subscriptions, not from advertising to kids. - How much screen time is okay for a three-year-old?
The American Academy of Pediatrics points to about an hour a day of high-quality content for ages two to five, and stresses watching or playing along when you can. Quality and company matter more than the exact minutes. - Is ABCmouse easy to cancel?
Cancel through your ABCmouse account settings before the trial or renewal date, not by deleting the app. The company settled an FTC case over auto-renewals that were hard to stop, so set a reminder. - What happened to Noggin?
The standalone Noggin preschool learning app was shut down, so we removed it. Do not pay for leftover listings; pick one of the live apps above instead.
How we tested
We installed each app on Android phones and tablets, set up a child profile, and worked through real activities the way a young child would, watching specifically for ad networks, purchase prompts a child could reach, and whether the learning held up. We re-check each app’s Play Store listing, price, and ads policy before publishing, and we drop any app that changes for the worse. Some links here may earn BFA a small commission, which never changes which apps we recommend or the order they appear in.
