# Double Pendulum vs Tiamat

The clearest difference is in-app purchases: Double Pendulum at none against Tiamat's 6. Double Pendulum also leads on iOS requirement (11.2 vs 26.0). Tiamat's advantage is ratings volume (117 vs 3). On price, rating, review sentiment and ads there is nothing between them.

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

Tiamat holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Tiamat has 117 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Double Pendulum's written reviews are positive against 92% of Tiamat's, so the app with the better star average is not the one people write more warmly about.
