Best Sight Word Apps for Kids (2026)

Sight words take weeks of practice, so the app has to be one your child comes back to. How each kind works, who it suits, and where we fit in.

Frequently asked questions

How many sight words should a kindergartner know?

There is no national number. The kindergarten standard names ten example words and specifies no count at all, and reading researcher Timothy Shanahan suggests about twenty words by the end of kindergarten, at least ten of them sight words. School targets commonly range from twenty-five to a hundred, and none of those figures comes from research. Twenty words known solidly beats a hundred half-remembered.

Are free sight word apps good enough?

For practicing a list of words, usually yes. Sight Words - Pre-k to 3rd covers the whole Dolch list free with no ads and no subscription, and Khan Academy Kids and Duolingo ABC cost nothing either. Paying is worth it when you need something free apps do not do, which for sight words is almost always one of two things, and they are practicing your own school's list or teaching the phonics underneath the list at the same time.

What about ABCmouse or Starfall for sight words?

Both are real programs and neither is in the comparison here, because in both, sight words sit inside a broad reading path rather than having a section of their own. If you want one subscription across several subjects, ABCmouse is covered in our phonics app comparison. If you want a large free tier, Starfall has one, and it is web-first rather than an app. For practicing a specific list of words, a dedicated app will do it in less time.

Can I use my child's school list in an app?

In a few of them. Most sight word apps practice a fixed list, usually Dolch, and let you choose which of those words to work on rather than add your own. Sight Words: Dolch Coach takes your own words and records them in your voice, though it has not been updated since 2019. Wonster Words takes them too, written or pasted in per child. Several apps that used to offer this are no longer maintained, which is why you will still see them recommended.

Can an app replace flashcards?

For the repetition, yes, and an app is better at it. It never gets tired, it gives feedback on every single word, and it keeps going on the evenings nobody has the energy to deal cards. What it cannot replace is an adult noticing how your child got the word. A child who reads "was" as "saw", or guesses "they" from the first letter, is telling you something a screen scores as simply wrong.

What age should we start?

Usually around five, and the signal is skills rather than a birthday. Sight word practice works once your child knows most letter sounds and can hear the separate sounds in a spoken word. Before that, an app that drills whole-word shapes is asking your child to memorize pictures with nothing to anchor them, which is slower rather than faster.

A cartoon phone standing in a storybook landscape of green hills, a waterfall and a far-off castle. Its screen shows a sight word game: the word “because” on a cloud, above a path of stepping stones leading to a lit doorway. Three word buttons sit on the path in front of the phone, reading “around”, “every” and “please”.
