Gravity Two vs Space Crash Simulator
Price, ratings, monetisation and update history for both games, side by side — with what reviewers say about each.
Gravity Two
Read full descriptionHide full description
Gravity Two is sequel to wildly (?) popular (what?) Gravity One. The idea is to get the triangle (that's you, The Player) to something that emits particles and avoid gravity wells (white circles). There are 32 levels. Some are easy, some may not be. Some have been tested, some are not. There are Game Center achievements for completing each of the levels and a leaderboard to show who is the best, based on total combined score of all levels. Warning: rage quitting may become popular way of playing this game....
Space Crash Simulator
Experience realistic planetary collisions with a powerful physics engine. Customize your own cosmic events by adjusting particle count, velocity, and accuracy, or jump straight into high-energy impacts. This app offers a detailed, physics-based simulation for educational or entertainment purposes.
- Smoothed Particle Hydrodynamics (SPH) simulation
- Real-time planetary collisions
- Customizable simulation parameters
- Setup Mode for scenario creation
- Adjustable particle count and accuracy
- Physics-based detailed simulation
Read full descriptionHide full description
Smash worlds together and watch them shatter, merge, and melt, driven by real physics, not pre-made animations. Every planet is made of thousands of interacting particles, so every collision is computed live and no two impacts ever look the same. Build your own scenario in Setup Mode: place up to 8 bodies, set their size, density, spin and velocity, then let gravity do the rest. Or dive straight into a head-on collision and watch the debris glow, cool, and form a crust. - True particle physics (SPH), the first of its kind on mobile - Molten impact zones: heat, lava, and cooling crusts - Give planets rings or shred a moon into one with tidal forces (Roche limit) - Protoplanetary disk and colliding-galaxies modes - Black holes that tear planets apart - Custom planet textures from your own photos - Runs on everything: tune particle count, accuracy, and timescale to your device

Verdict
The clearest difference is in-app purchases: Gravity Two at none against Space Crash Simulator's 1. Gravity Two also leads on ads (none vs shown) and iOS requirement (8.0 vs 15.0). Space Crash Simulator's advantage is update cadence (every 4 days vs every 11 months). On price and device support there is nothing between them.
