# Gun Builder Custom Guns vs Gun Builder Simulator

The clearest difference is update cadence: Gun Builder Custom Guns at every 5 weeks against Gun Builder Simulator's every 5 months. Gun Builder Custom Guns also leads on rating (4.5 vs 4.3) and ratings volume (1.6K vs 307). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Gun Builder Custom Guns sells 1 one-off in-app purchase and Gun Builder Simulator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Gun Builder Custom Guns holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Gun Builder Custom Guns has 1.6K ratings behind it against 307, so its average is the more settled of the two. Written reviews complicate that: 64% of Gun Builder Custom Guns's written reviews are positive against 68% of Gun Builder Simulator's, so the app with the better star average is not the one people write more warmly about.

Gun Builder Custom Guns ships an update every 5 weeks, Gun Builder Simulator every 5 months. The most recent releases landed on September 19, 2026 and September 18, 2026 respectively.
