The best apps for kindergarteners, with the price and the catch

Prices checked September 21, 2026.

I made one of the apps on this list, so read it knowing that. I’ve still tried to be fair. Most of the good ones are free, and several of the paid ones charge you every month.

What to check before you download anything

Ads, even in paid apps. A 2019 study of 135 apps in the 5 and under category found ads in 129 of them, including 88% of the paid ones. Paying doesn’t mean there aren’t any.

Free until the trial ends. A lot of these are free to download and a subscription after that. In 2020, the company behind ABCmouse paid $10 million to settle FTC charges that it didn’t clearly say memberships renewed and made cancelling hard.

Built for them alone, or for you both. Most kids’ apps are built so a kid can play by themselves. That’s fine for a car ride. If you want time together, look for one that gives you something to do too.

The list

Khan Academy Kids

Where I’d start. It’s from a nonprofit, it’s free, and its Google Play listing says it’s 100% ad-free.

PBS KIDS Games

Free, and built around shows your kid may already know, which makes it an easy first app.

Starfall

The app is free and some of it is for members. It runs all the way to fifth grade, so it lasts a while.

Duolingo ABC

Free, with nothing to buy inside it, and it sticks to one job: learning to read.

Endless Alphabet

You pay once and you’re done. It’s about words more than letters, which is a nice step up.

Lingokids

Free to download, with a subscription for the rest. Its App Store listing says it’s ad-free.

Homer

A subscription. Its App Store listing says it’s ad-free with no cancellation fees.

ABCmouse

The biggest curriculum on this list, and a subscription. Read how it renews before you start the trial.

Side by Play

Mine. It’s built for you to sit next to your kid and play it together, 15 minutes before bed. No ads, no accounts, nothing to buy inside it.

If you only get one

If you want one free app, get Khan Academy Kids. If you want something you and your kid do together at night, that’s the reason I made Side by Play.
