Verdict

The call

The clearest difference is price: Readability at Free against Simplex Spelling Phonics CVC's $4.99. Readability also leads on rating (4.6 vs 3.7) and update cadence (fortnightly vs every 13 months). Simplex Spelling Phonics CVC's advantage is review sentiment (100% vs 56%) and in-app purchases (none vs 2). On ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Readability holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Readability has 24K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 100% of Simplex Spelling Phonics CVC'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

Simplex Spelling Phonics CVC ships an update every 13 months, Readability fortnightly. The most recent releases landed on July 21, 2026 and September 27, 2026 respectively.
