# iSpellBetter vs Readability

The clearest difference is rating: Readability at 4.6 against iSpellBetter's 3.3. Readability also leads on update cadence (fortnightly vs every 21 months) and ratings volume (25K vs 7). iSpellBetter's advantage is in-app purchases (none vs 2) and iOS requirement (8.0 vs 16.4). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Readability sells 2 in-app purchases, starting at $19.99 per month. iSpellBetter asks for nothing beyond the download.

Readability holds the better App Store score, 4.6 against 3.3. That said, the two scores are not equally well evidenced: Readability has 25K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 60% of iSpellBetter'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.

iSpellBetter ships an update every 21 months, Readability fortnightly. The most recent releases landed on October 6, 2026 and October 18, 2026 respectively.
