Learning Apps That Really Work Offline: What to Check Before a Trip

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. Some apps that say they work offline mean something smaller: an offline section, a selection of videos, or books saved ahead of time. The companies that make them say so in their own help pages.

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.

We make Wonster Words, one of the six apps this guide compares.

Which learning apps for kids really work offline?

Kids’ learning apps describe offline play in three different ways: the whole app, an offline section, or saved downloads. The table quotes what each company publishes about its own app, read in October 2026, except Starfall, which we tried ourselves.

App	What works offline, in its maker’s words	What it needs
Wonster Words	Full features available offline: all content, including videos	Content downloaded first. Signing in, purchases, profile changes, and new downloads need a connection
Khan Academy Kids	”Kodi’s Suitcase”, a section of the Library with stories, letters, numbers, logic, and letter tracing, plus “Create” (help center)	Wi-Fi to create the account
ABCmouse	An Offline Mode with “a selection of ABCmouse learning videos and games” (support page)	A Premium subscription. Otherwise the app “cannot load all its regular activities” offline
Epic	Books saved for offline reading, not audiobooks or videos (help center)	An Epic Family or School Plus plan, and a connection to sign in and download
Duolingo ABC	”Enjoy playing and learning offline” (its App Store listing)	The listing does not say which parts
Starfall (main app)	Did not work offline when we tried it in September 2026	A connection

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. Check which kind your child’s app has before the plane takes off: the app maker’s own wording usually tells you.

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. Something still needs the internet, usually signing in and buying, so check what.
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.
3. Saved downloads. You choose books or videos ahead of time and only those play. It works well for reading, and it depends on remembering to save them.

Ask two questions of any app. What exactly works offline, and does it need anything first: a paid plan, a download, or a sign-in? The answers are usually on the app’s own help center. 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 it, 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.

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.

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.
• iPads go offline most: kids on iPad start offline more than three times as often as kids on iPhone.

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.

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. What works at 3 is wrong at 6. 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.

Free or paid: what offline play costs

Offline play is free in some apps and part of a paid plan in others. Khan Academy Kids and Duolingo ABC are free. 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.

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 audio is half of most early reading apps.
• Leave a few minutes for the app to finish downloading before you switch the Wi-Fi off.

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.
