# Solar Smash vs Water Physics Simulation

The clearest difference is rating: Solar Smash at 4.8 against Water Physics Simulation's 4.2. Solar Smash also leads on ratings volume (392K vs 4.6K) and update cadence (every 4 weeks vs every 2 months). Water Physics Simulation's advantage is iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Solar Smash sells 10 one-off in-app purchases and Water Physics Simulation sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Solar Smash holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Solar Smash has 392K ratings behind it against 4.6K, so its average is the more settled of the two. Written reviews point the same way: 85% of Solar Smash's written reviews are positive against 76% of Water Physics Simulation's.

Solar Smash ships an update every 4 weeks, Water Physics Simulation every 2 months. Both last shipped on September 24, 2026.
