# Fluid Ship Simulator Sandbox vs Water Box

The clearest difference is review sentiment: Water Box at 92% against Fluid Ship Simulator Sandbox's 23%. Water Box also leads on rating (4.8 vs 2.6) and ratings volume (1.8K vs 94). Fluid Ship Simulator Sandbox's advantage is update cadence (every 2 days vs every 9 days). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Fluid Ship Simulator Sandbox sells 1 one-off in-app purchase and Water Box sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
