Space Crash Simulator vs Aphelion
Price, ratings, monetisation and update history for both games, side by side — with what reviewers say about each.
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

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 rating: Aphelion at 4.9 against Space Crash Simulator's 4.5. Aphelion also leads on review sentiment (100% vs 81%) and update cadence (every 2 days vs every 5 days). Space Crash Simulator's advantage is ratings volume (723 vs 17). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Space Crash Simulator sells 1 one-off in-app purchase and Aphelion sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Aphelion holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Space Crash Simulator has 723 ratings behind it against 17, so its average is the more settled of the two. Written reviews point the same way: 81% of Space Crash Simulator's written reviews are positive against 100% of Aphelion's.
Space Crash Simulator ships an update every 5 days, Aphelion every 2 days. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
