# Rain Drop vs Water Physics Simulation

The clearest difference is rating: Rain Drop at 5.0 against Water Physics Simulation's 4.2. Rain Drop also leads on in-app purchases (none vs 5). Water Physics Simulation's advantage is update cadence (every 2 months vs every 75 months) and ratings volume (4.6K vs 1). On price, ads, device support and iOS requirement there is nothing between them.

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

Rain Drop holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Water Physics Simulation has 4.6K ratings behind it against 1, so its average is the more settled of the two.

Rain Drop ships an update every 75 months, Water Physics Simulation every 2 months. The most recent releases landed on November 3, 2026 and November 9, 2026 respectively.
