Verdict
The clearest difference is review sentiment: MoreBlanks at 100% against O'Reilly's 46%. O'Reilly's advantage is price (Free vs $1.99) and rating (4.7 vs 4.0). On ads, in-app purchases, device support and iOS requirement 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
O'Reilly is free to download; MoreBlanks costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
O'Reilly holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: O'Reilly has 34K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 100% of MoreBlanks's written reviews are positive against 46% of O'Reilly's, so the app with the better star average is not the one people write more warmly about.
MoreBlanks ships an update monthly, O'Reilly fortnightly. The most recent releases landed on October 31, 2026 and November 5, 2026 respectively.
