# Dummy Defense vs Gravity Platform

The clearest difference is price: Gravity Platform at Free against Dummy Defense's $0.99. Gravity Platform also leads on update cadence (every 2 days vs every 5 months). Dummy Defense's advantage is ratings volume (57 vs 3) and device support (3 vs 1). On rating, ads, in-app purchases and monetization model there is nothing between them.

Gravity Platform is free to download; Dummy Defense costs $0.99 up front. Dummy Defense sells 3 one-off in-app purchases and Gravity Platform sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.2 for Dummy Defense against 4.3 for Gravity Platform. That said, the two scores are not equally well evidenced: Dummy Defense has 57 ratings behind it against 3, so its average is the more settled of the two.
