# Unit Conversion vs Pattern Generator

The clearest difference is rating: Pattern Generator at 5.0 against Unit Conversion's 4.6. Unit Conversion's advantage is update cadence (every 3 months vs every 19 months) and ratings volume (102 vs 1). On ads, in-app purchases and device support there is nothing between them.

Unit Conversion costs $0.99 and Pattern Generator $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Pattern Generator holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Unit Conversion has 102 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 74% of Unit Conversion's written reviews are positive against 50% of Pattern Generator's, so the app with the better star average is not the one people write more warmly about.

Unit Conversion ships an update every 3 months, Pattern Generator every 19 months. The most recent releases landed on September 21, 2026 and September 9, 2026 respectively.
