***** 24x7digital's SightWords app has been featured as an iTunes App Store Staff Pick! Help your young learner master the most frequently used words in the English language! 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". Our SightWords app is a handy way to encourage a child's mastery of their sight words either as part of a structured reading program at school, or as an impromptu study session when standing in line at the grocery store. SightWords Pro contains a selection of over 1,600+ sight words which comprises up to 85% of the text in a child's early reading materials -- comprehensively compiled from Dolch, Fry, Pinnell-Fountas, UK, and many other high-frequency word lists. Choose a pre-defined flash card word list, or build and save custom flash card lists to match what is taught in the classroom. Add custom words and record your own pronunciations. Mark flash cards with stars or flags. Flash cards respond to swipes and taps. Shake your device to shuffle the words. Beautiful voice-pronunciations for all included words. FEATURES: • Over 1,600+ essential sight words • Upper and lower-case alphabet, numbers 0-100, colors, shapes, animals, months • Beautifully recorded American-English pronunciations for all words • Words organized by number of letters • Customizable word lists with copy/paste • Add your own words • Record your own pronunciations • Simple textual editing of word lists • Export your custom word lists as text • Mark flash cards with stars or flags • Flash cards respond to swipes and taps • Shake to shuffle words • In-app Help documentation • Universal app optimized for iPhone, iPod touch, and iPad TRY OUR OTHER APPS: TeachMe: Toddler, TeachMe: Kindergarten, TeachMe: 1st Grade, TeachMe: 2nd Grade, TeachMe: 3rd Grade, TeachMe: Math Facts.

Verdict
The clearest difference is price: Readability at Free against SightWords Pro's $0.99. Readability also leads on rating (4.6 vs 3.9) and update cadence (fortnightly vs every 4 months). SightWords Pro's advantage is in-app purchases (none vs 2) and review sentiment (76% vs 56%). On ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Readability is free to download; SightWords Pro costs $0.99 up front. Readability sells 2 in-app purchases, starting at $19.99 per month. SightWords Pro asks for nothing beyond the download.
Readability holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: Readability has 25K ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 76% of SightWords Pro'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.
SightWords Pro ships an update every 4 months, Readability fortnightly. The most recent releases landed on October 16, 2026 and October 18, 2026 respectively.
