# Aster vs CrossMath

The clearest difference is in-app purchases: Aster at none against CrossMath's 5. Aster also leads on ads (none vs shown) and review sentiment (100% vs 70%). CrossMath's advantage is update cadence (every 4 days vs every 2 months) and ratings volume (129 vs 5). On price and device support there is nothing between them.

Both are free to download. CrossMath sells 5 one-off in-app purchases. Aster asks for nothing beyond the download.

Aster holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: CrossMath has 129 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 100% of Aster's written reviews are positive against 70% of CrossMath's.

Aster ships an update every 2 months, CrossMath every 4 days. The most recent releases landed on October 6, 2026 and October 25, 2026 respectively.
