Best Offline Learning Apps for Kids: Which Really Work?

A learning app that really works offline keeps every activity, its audio, and your child’s progress working in airplane mode, with nothing to sign in to halfway through. We tested five apps that way. Wonster Words has full features available offline once its content is downloaded, and Duolingo ABC worked offline too. The other three keep part of the app offline: Khan Academy Kids an offline section, ABCmouse an Offline Mode for Premium subscribers, and Epic the books, audiobooks, and videos you download ahead of time.

We make Wonster Words, one of the five apps this guide compares, and we tested it the same way as the other four.

The way to know is a five-minute test: put the device in airplane mode and open every activity your child uses. Offline play is common: nearly 1 in 11 Wonster Words sessions starts with no internet connection, according to our own app data on offline play. The share is higher on iPads and on travel days.

Which learning apps for kids really work offline?

Wonster Words works offline as a whole, Duolingo ABC keeps a preset stretch of its lessons, and Khan Academy Kids, ABCmouse, and Epic each keep part of the app offline. We tested each app in airplane mode in October 2026, and the table shows what works offline in each one and who decides what is on the device.

App, and who it is made for	What works offline	Who chooses what is offline
Wonster Words, ages 2–8	Full features: all content, including videos. Progress syncs once the device is back online	All of it can be downloaded ahead of time
Khan Academy Kids, ages 2–8	A section labeled “Offline”, with stories, letters, numbers, logic, and letter tracing, plus “Create” for coloring and drawing	The app. The set is preset, and it does not update
ABCmouse, ages 2–8	For Premium subscribers, an Offline Mode with a selection of learning videos and games. Without Premium, there is no offline mode	The app. The selection is preset
Epic, kids 12 and under	For Epic Family and School Plus plans, every book, audiobook, and video you download	You. Download each book, audiobook, or video ahead of time
Duolingo ABC, ages 3–8	Its lessons, from what it has downloaded	The app. It keeps a preset stretch of its lesson path downloaded, and we found no published limit on how much

Every app in this comparison needs a connection to create an account and sign in, free or paid, so do both at home before you rely on offline play.

A partial offline mode can still be the right one. A library of saved books, like Epic’s, is exactly what a long flight needs.

What does “works offline” actually mean?

“Works offline” covers three different things, and the difference decides what your child can do on a plane.

1. The whole app works offline. Lessons are downloaded once, then every activity runs with no connection, and progress syncs when the device reconnects. Something still needs the internet, usually signing in and buying, so check what. Duolingo ABC is close to this: rather than the whole app, it keeps a preset stretch of its lesson path downloaded, so offline play carries on through those lessons.
2. An offline section. The app keeps one part available offline, such as a shelf of stories or a set of videos, and the rest waits for a connection. A child who heads for their usual game finds it unavailable. Some apps choose what goes in it for you, as Khan Academy Kids and ABCmouse do, and Khan Academy Kids’ set never updates, so a child may get through it over several trips.
3. Saved downloads. You choose books, audiobooks, videos, or lessons ahead of time and only those play, as Epic does. It works well for reading, and it depends on remembering to save them.

Ask three questions of any app: what works offline, who chooses it (you or the app), and whether offline play needs a paid plan. An app’s help center is a place to start, but in our testing some help pages did not match the app. Trying the app in airplane mode is the only sure answer. ABCmouse’s support page goes further and tells parents to test its Offline Mode in airplane mode to confirm it is working.

How to test an app’s offline mode before a trip

The only reliable check is to try the app offline yourself, the evening before you leave rather than at the gate. It takes about five minutes:

1. 1

   Open the app on Wi-Fi first

   While you still have Wi-Fi, sign in, open the app, and download any lessons, books, or videos it offers to save. Leave it open for a few minutes so downloads finish.

2. 2

   Turn on airplane mode

   Switch on airplane mode and make sure Wi-Fi is off too. On a Wi-Fi-only iPad, turning off Wi-Fi is enough.

3. 3

   Open every activity your child uses

   Do not stop at the home screen. Tap into each game, book, and lesson your child actually plays, because some apps keep only one section working offline.

4. 4

   Listen for the audio

   Play a word or a story and check that you hear it. Audio that streams from the internet can fail even when the screen loads.

5. 5

   Close the app and open it again

   Quit the app fully and reopen it while still offline. Some apps work once they are open but ask for a connection at launch.

6. 6

   Reconnect and check the progress

   Turn airplane mode off and open the app's progress or parent view. What your child just did offline should be there once the app syncs.

Do it on the device your child will use. An iPad is far more likely to be offline than a phone: in our own data, kids on iPad start a session offline more than three times as often as kids on iPhone. About nine in ten of the most-used iPads are Wi-Fi-only models, with no cellular connection of their own, according to the iPad survey from TelemetryDeck.

How to choose an offline learning app: what to look for besides offline

Offline is one test, not the whole decision. An app that works perfectly on a plane still has to teach well. The American Academy of Pediatrics no longer sets a number of minutes for young children’s screen time: its January 2026 policy statement asks parents to look at the content itself. Four things matter alongside offline play:

• It teaches the skill your child is working on. For reading, that means systematic, explicit phonics, the approach the National Reading Panel found effective. Our guide to the best phonics apps compares the main options.
• It fits your child’s age. Four of the five apps in the table say they are made for children from 2 or 3 up to 8, and Epic’s library runs to 12. For a toddler, start with an app made from age 2, such as Wonster Words, Khan Academy Kids, or ABCmouse. Run the airplane-mode test on the activities a 2-year-old can do alone. What works at 3 is wrong at 6, and the guide to reading apps by age sorts the choices that way.
• It has no ads and no way out to the internet. This matters online and offline alike, and our guide to ad-free reading apps compares the options. Our guide to kids’ app safety shows how to read an app’s privacy label.
• It works on your device. An app has to be in your tablet’s app store before it can work offline. Our guide to the best tablet for kids covers the choice of device.

Are there free kids’ apps that work offline?

Yes: Khan Academy Kids and Duolingo ABC are free, and both have offline play. ABCmouse keeps its Offline Mode for Premium subscribers, and Epic’s offline reading is for its paid Family and School Plus plans. Wonster Words costs $10.99 a month or $59.99 a year, with a 7-day free trial, and offline play is part of it.

Check offline during a free trial. A trial is the cheapest moment to run the airplane-mode test, before you have paid for an app you cannot use on a plane. If you are switching away from ABCmouse, our guide to ABCmouse alternatives covers the other differences.

Why does offline matter for young children?

Offline play is not an edge case. Nearly 1 in 11 Wonster Words sessions starts with no internet connection, and more than 43,000 kids played offline in the last year. The figures are from our study of offline play, which also found when it happens:

• The morning school run is the busiest offline hour of the day, and the share falls through the evening.
• Travel days rise sharply. The share of sessions starting offline was 37% higher than usual on the Wednesday before Thanksgiving, one of the busiest travel days of the year according to AAA. Holidays spent at home stayed flat.

Offline is also a quieter way to play. With no connection, a child cannot be pulled toward ads, links, or online video. To keep that quiet once the device reconnects, check that an app has no ads and no way to reach the internet from inside it.

Getting the tablet ready for a flight or road trip

Download and test the night before, on home Wi-Fi:

• Open each app your child will use and save its lessons, books, or videos.
• Run the five-minute airplane-mode test on that device.
• Charge the tablet and pack headphones, since early reading apps teach by sound.

For the rest of the trip, our travel guide for kids’ flights and road trips adds car games that need no screen.

Beyond reading: other offline apps worth loading

A long trip needs more than one kind of app. Drawing, puzzle, and story apps keep a child busy between lessons, and the same test applies: airplane mode, then every activity. Saved books are the simplest offline option of all, which is why a library app with downloads, such as Epic, pairs well with a learning app on a long flight.
