# Polygrams vs Osmo Tangram

The clearest difference is rating: Polygrams at 4.6 against Osmo Tangram's 4.1. Polygrams also leads on ratings volume (4.4K vs 166). Osmo Tangram's advantage is in-app purchases (none vs 6) and ads (none vs shown). On price, update cadence, monetization model and device support there is nothing between them.

Both are free to download. Polygrams sells 6 one-off in-app purchases. Osmo Tangram asks for nothing beyond the download.

Polygrams holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: Polygrams has 4.4K ratings behind it against 166, so its average is the more settled of the two. Written reviews complicate that: 44% of Polygrams's written reviews are positive against 56% of Osmo Tangram's, so the app with the better star average is not the one people write more warmly about.

Polygrams ships an update every 6 weeks, Osmo Tangram every 2 months. The most recent releases landed on November 11, 2026 and November 4, 2026 respectively.
