# Euclidea vs Tangram King

The clearest difference is ads: Euclidea at none against Tangram King's shown. Euclidea also leads on rating (4.8 vs 4.6) and ratings volume (938 vs 154). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. Euclidea sells 6 one-off in-app purchases and Tangram King sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Euclidea holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Euclidea has 938 ratings behind it against 154, so its average is the more settled of the two. Written reviews complicate that: 86% of Euclidea's written reviews are positive against 89% of Tangram King's, so the app with the better star average is not the one people write more warmly about.

Euclidea ships an update every 3 months, Tangram King every 4 months. The most recent releases landed on October 29, 2026 and October 26, 2026 respectively.
