A sight words app helps young children learn the common words they'll meet again and again in books, through flash cards, games and short reading activities. Some are free, some follow Dolch lists, and some mix sight words with phonics. Ten apps follow, in no particular order.
Sight words are the little words that turn up on almost every page of a children's book, words like the, said and was. Many of them don't follow the usual spelling patterns, so children learn to recognise them quickly rather than sounding them out every time.
The ten apps below are listed alphabetically and in no particular order, and every description comes from the app's own App Store listing, read this week. If your child is also starting to write, my list of kindergarten writing prompts pairs well with reading practice.
Sight words apps at a glance
I checked the free plan column on each app's own App Store listing, as of Oct 2026. Yes means the listing names a free app, a free version, a free tier or free content. Trial only means a time-limited trial. Not stated means the listing I read named neither, even where there's a download button, so check the app's own page before you subscribe.

What the research says about sight words
Sight word practice works best as one part of learning to read, not the whole of it. The Institute of Education Sciences, through its What Works Clearinghouse practice guide on foundational reading skills from kindergarten to third grade, recommends teaching children to decode words, analyse word parts, and write and recognise words.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
The same guide recommends that each student reads connected text every day. So an app that drills single words is useful, but it should sit alongside real books, where your child meets those words in sentences and stories.
How to fit an app into reading time
- Keep app sessions short, around ten minutes, and stop while it's still fun.
- Sit with your child for the first few sessions so you know what it's teaching.
- Point out the same words in a picture book straight afterwards.
- Turn off sound effects or rewards that distract more than they help.
- Check the privacy section on the listing before you hand over the tablet.
Signs your child is ready for more
When your child reads the common words on sight without pausing, it's time to move on. Look for an app that adds short sentences, simple stories or phonics, so the skill grows into reading rather than stopping at word recognition.
If your child is struggling or getting upset, take a break. Every child learns to read at a different pace, and a teacher can tell you whether extra help would be useful.

My plain advice on sight words apps
Choose one app your child enjoys, keep sessions short, and always follow up with a real book. A free flash card app is plenty for practising a school list. If you'd like something more complete, pick a program that mixes sight words with phonics and daily reading, because that's what the research supports.
