# Square Panda Lagoon vs Osmo Coding Duo

The clearest difference is rating: Osmo Coding Duo at 3.9 against Square Panda Lagoon's 2.7. Osmo Coding Duo also leads on ratings volume (145 vs 17) and device support (3 vs 1). Square Panda Lagoon's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (8.0 vs 15.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Osmo Coding Duo holds the better App Store score, 3.9 against 2.7. That said, the two scores are not equally well evidenced: Osmo Coding Duo has 145 ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 60% of Square Panda Lagoon's written reviews are positive against 53% of Osmo Coding Duo's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 15, 2026 and September 25, 2026 respectively.
