Smiley Sight Words teaches high-frequency sight words to your child! The 1,600+ sight words included with Smiley Sight Words comprises up to 85% of the text in a child's early reading materials. A child who can recognize just 8 of 10 words in a sentence can typically understand its meaning! "Sight words" often cannot be illustrated via simple pictures or sounded out according to regular phonetic decoding rules, thus they need to be learned and recognized "on sight". Smiley Sight Words is a handy way to keep track of and encourage a child's mastery of their sight words.

Verdict

The call

The clearest difference is price: Readability at Free against Smiley Sight Words's $0.99. Readability also leads on rating (4.6 vs 4.2) and update cadence (fortnightly vs every 3 months). Smiley Sight Words's advantage is in-app purchases (none vs 2) and review sentiment (88% vs 56%). On ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Readability holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Readability has 25K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 88% of Smiley Sight Words's written reviews are positive against 56% of Readability's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Smiley Sight Words ships an update every 3 months, Readability fortnightly. The most recent releases landed on October 22, 2026 and October 25, 2026 respectively.
