Verdict
The clearest difference is rating: Polygrams at 4.6 against Osmo Tangram's 4.1. Polygrams also leads on ratings volume (4.3K 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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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 4.3K 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 6, 2026 and November 4, 2026 respectively.
