# ABA vs Reading Eggs

The clearest difference is price: Reading Eggs at Free against ABA's $0.99. Reading Eggs also leads on rating (4.7 vs 4.2) and update cadence (every 4 weeks vs every 72 months). ABA's advantage is in-app purchases (none vs 4) and review sentiment (67% vs 55%). On ads and device support there is nothing between them.

Reading Eggs is free to download; ABA costs $0.99 up front. Reading Eggs sells 4 in-app purchases, starting at $9.99 per month. ABA asks for nothing beyond the download.

Reading Eggs holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Reading Eggs has 7.3K ratings behind it against 32, so its average is the more settled of the two. Written reviews complicate that: 67% of ABA's written reviews are positive against 55% of Reading Eggs's, so the app with the better star average is not the one people write more warmly about.

ABA ships an update every 72 months, Reading Eggs every 4 weeks. The most recent releases landed on September 28, 2026 and October 2, 2026 respectively.
