# Robomaker® vs Water Physics Simulation

Robomaker® and Water Physics Simulation both sit at 4.3 stars, but that hides the real split: 76% of Water Physics Simulation's written reviews are positive against 22% of Robomaker®'s. Water Physics Simulation also leads on ratings volume (4.6K vs 4). Robomaker®'s advantage is in-app purchases (none vs 5) and ads (none vs shown). On price, rating and device support there is nothing between them.

Both are free to download. Water Physics Simulation sells 5 one-off in-app purchases. Robomaker® asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.3 for Robomaker® against 4.2 for Water Physics Simulation. That said, the two scores are not equally well evidenced: Water Physics Simulation has 4.6K ratings behind it against 4, so its average is the more settled of the two. Written reviews are what separate them: 22% of Robomaker®'s written reviews are positive against 76% of Water Physics Simulation's.

Robomaker® ships an update every 4 weeks, Water Physics Simulation every 2 months. The most recent releases landed on October 11, 2026 and October 21, 2026 respectively.
