# Flop Rocket vs Spaceflight Simulator

The clearest difference is update cadence: Spaceflight Simulator at every 9 days against Flop Rocket's every 3 months. Spaceflight Simulator also leads on ratings volume (97K vs 377). Flop Rocket's advantage is iOS requirement (13.0 vs 15.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Flop Rocket sells 6 one-off in-app purchases and Spaceflight Simulator sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Flop Rocket against 4.8 for Spaceflight Simulator. That said, the two scores are not equally well evidenced: Spaceflight Simulator has 97K ratings behind it against 377, so its average is the more settled of the two. Written reviews are what separate them: 81% of Flop Rocket's written reviews are positive against 86% of Spaceflight Simulator's.

Flop Rocket ships an update every 3 months, Spaceflight Simulator every 9 days. The most recent releases landed on September 15, 2026 and September 26, 2026 respectively.
