# Double Pendulum vs Physarum

The clearest difference is in-app purchases: Double Pendulum at none against Physarum's 6. Double Pendulum also leads on iOS requirement (11.2 vs 26.0). Physarum's advantage is rating (4.8 vs 4.5) and ratings volume (27 vs 2). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Physarum sells 3 one-off in-app purchases. Double Pendulum asks for nothing beyond the download.

Physarum holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Physarum has 27 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
