A first grader can sound out cat and dog, then stops cold at said and was. Those words do not follow the rules, and they show up in almost every sentence a young reader meets. That is the daily problem with sight words: children need to recognize them instantly, and instant recognition only comes from repeated, low-stress practice.
Apps help when they give that repetition without turning it into a test. The best ones on this list mix short games with reading in context, let a child hear the word, spell it, and use it in a sentence, and let you see which words still trip a student up. A few are free, a few cost a few dollars, and a couple are full programs where sight words are one strand among many.
How we picked: we started from a researched shortlist, then checked each tool's official website on November 1, 2026. Where a detail comes from an app store instead, the guide says so. We weighted fit for kindergarten through 2nd grade classrooms, whether the sight word content is easy to find inside the app, and whether teachers can get started for free.
Key takeaways

How we chose
We started from tools PreK–6 teachers actually use and checked every one against its official website, pricing page and feature pages on November 1, 2026. We kept tools that fit elementary classrooms, noted whether a free plan exists, and wrote down honest limitations next to the strengths. Nobody paid to be included, and we don't use affiliate links on this page.
- Fit for PreK–6 classrooms, special education or homeschool
- Clear information on the official site about what the tool does and who it is for
- Free plan or free-for-teachers option noted where one exists
- Still active and maintained, with rebrands noted
How to choose the right tool
Match the app to the words you actually teach. Endless Reader and Bob Books cover a fixed set of common words, while Vocabulary A-Z lets you enter your own list. If your school follows a set sequence such as Fry or Dolch, a tool that takes custom lists saves you from teaching two lists at once.
Decide whether sight words are the lesson or a strand. Khan Academy Kids, Endless Reader, and Bob Books are built around sight words, so they fit a short daily routine. ABCmouse, SplashLearn, and HOMER bury sight words inside a bigger program, which is fine for a center but harder to track word by word.
Check the free path before you recommend anything to families. Khan Academy Kids is free outright, SplashLearn is free for teachers, and ABCmouse has a free Basic plan. A paid app with a small free sample, such as Endless Reader, is easier to try than one with no free version at all.
Watch how a child gets a word wrong. A good sight word app shows the spelling, says the word, and uses it in a sentence, the way the Khan Academy Kids videos do. If an app only flashes the word and marks answers right or wrong, it is testing memory rather than teaching it.
Plan for the device you actually have. Several of these apps are paid downloads on tablets, and a couple show different prices in different app stores. Confirm the price and the login steps on one device before rolling an app out to a whole class.

Frequently asked questions
What is the best free sight word app for kindergarten?
Khan Academy Kids is the strongest free starting point: it is run by a nonprofit, has no ads or subscriptions, and includes 20+ sight word videos that spell each word, define it, and use it in a sentence. Endless Reader also lets children try six words free.
Do any of these apps let me use my own sight word list?
Yes. Vocabulary A-Z is built around premade and custom word lists, so you can enter the exact words your class is learning and get games, quizzes, and printable lesson plans for them. It is a paid classroom tool with a 14-day free trial.
Which sight word app is free for teachers?
SplashLearn is free for teachers to use in the classroom, and homework assigned through it stays free for students at home. Khan Academy Kids is free for everyone, and ABCmouse offers a free Basic plan with limits.
Are these apps good for 2nd graders, or only for kindergarten?
Most cover kindergarten through 2nd grade, but the youngest-focused ones, Endless Reader and Bob Books Reading Magic, target ages 3–5 and may feel too easy for 2nd graders. Monkey Word School Adventure, ABCmouse, SplashLearn, HOMER, and Vocabulary A-Z all reach into 2nd grade and beyond.
Can I use these apps for sight word homework?
Yes, with a quick check first. Khan Academy Kids and ABCmouse work at home with no cost, and SplashLearn assignments stay free for students. Paid apps such as HOMER and Vocabulary A-Z need a family or school subscription after the trial, so confirm who pays before assigning them.
