Verdict

The call

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 update cadence, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

MoreBlanks ships an update every 3 weeks, O'Reilly every 2 weeks. The most recent releases landed on August 21, 2026 and September 24, 2026 respectively.
