# ZipGrade vs YaYa Math

The clearest difference is in-app purchases: YaYa Math at none against ZipGrade's 1. ZipGrade's advantage is ratings volume (37K vs 1) and iOS requirement (13.0 vs 15.1). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. ZipGrade sells 1 one-off in-app purchase. YaYa Math asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for ZipGrade against 5.0 for YaYa Math. That said, the two scores are not equally well evidenced: ZipGrade has 37K ratings behind it against 1, so its average is the more settled of the two.

ZipGrade ships an update every 6 weeks, YaYa Math every 2 months. The most recent releases landed on October 31, 2026 and October 28, 2026 respectively.
