# MekaMon vs Water Physics Simulation

The clearest difference is in-app purchases: MekaMon at none against Water Physics Simulation's 5. MekaMon also leads on ads (none vs shown) and update cadence (monthly vs every 2 months). Water Physics Simulation's advantage is ratings volume (4.6K vs 23) and review sentiment (76% vs 64%). 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. MekaMon asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.3 for MekaMon 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 23, so its average is the more settled of the two. Written reviews are what separate them: 64% of MekaMon's written reviews are positive against 76% of Water Physics Simulation's.

MekaMon ships an update monthly, Water Physics Simulation every 2 months. The most recent releases landed on September 24, 2026 and October 13, 2026 respectively.
