# Builderment Idle vs Survivor Base

The clearest difference is rating: Survivor Base at 4.6 against Builderment Idle's 3.1. Survivor Base also leads on ratings volume (660 vs 22). Builderment Idle's advantage is update cadence (every 4 days vs every 3 weeks). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Builderment Idle sells 4 one-off in-app purchases and Survivor Base sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
