# Main Idea vs Square Panda Lagoon

The clearest difference is rating: Main Idea at 3.7 against Square Panda Lagoon's 2.7. Main Idea also leads on device support (3 vs 1). Square Panda Lagoon's advantage is in-app purchases (none vs 3) and update cadence (every 2 months vs every 22 months). On price and ads there is nothing between them.

Both are free to download. Main Idea sells 3 one-off in-app purchases. Square Panda Lagoon asks for nothing beyond the download.

Main Idea holds the better App Store score, 3.7 against 2.7. That said, the two scores are not equally well evidenced: Square Panda Lagoon has 17 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 42% of Main Idea's written reviews are positive against 60% of Square Panda Lagoon's, so the app with the better star average is not the one people write more warmly about.

Main Idea ships an update every 22 months, Square Panda Lagoon every 2 months. Both last shipped on November 2, 2026.
