SimplePhysics vs Evolution
Price, ratings, monetisation and update history for both games, side by side — with what reviewers say about each.
SimplePhysics
Design and simulate complex structures using a realistic physics engine. Test your creations by applying stress, using a finger to push and pull, or even creating explosions. Analyze strain distribution to identify weak points and refine your designs for strength and cost-effectiveness.
- Realistic physics simulation
- Blueprint editor
- Stress display
- Finger Test with explosions
- Ragdoll physics
- Slow motion mode

SimplePhysics lets you design complex structures for everything from tree houses to ferris wheels and then simulates your design with a sophisticated physics engine. A wise person once said: "An engineer is someone who can do for a dime what any fool can do for a dollar." In SimplePhysics, your design must not only be strong enough, it must be cheap enough to win. Create your design in seconds with the blueprints editor. If you make a mistake, simply tap the Undo button. Zoom in and out by pinching the screen and pan the view using a two finger drag. While testing, you can see how the strain is distributed across your design. Areas that are under immense strain are colored bright red, while other areas are colored green. This allows you to find and fix problem areas in your design. The finger test lets you use your finger to push and pull on your design. You can use this with pinpoint accuracy, or you can just smash your design to smithereens. The finger test has an explosive new twist. You can now create explosions by tapping the screen for ultimate annihilation. The newly added Bomb Shack level includes a dummy with full support for ragdoll physics. Throw him around, blow him up, and smash him against your design. The slow motion feature lets you slow things down so you can see how your design is failing, and it is also incredibly fun to watch explosions destroying your design in slow motion. Features * Realistic physics simulation * Ragdoll physics * Slow motion mode * Stress display shows problem areas in your design * Wide variety of levels! * Finger Test - smash your design to pieces, or blow it up with realistic explosions! * Save/Load designs * E-mail your blueprints to your friends * Universal support for the iPad
Evolution
Design and build unique creatures using joints, bones, and muscles. Witness their learning and improvement through evolutionary algorithms and neural networks as they tackle tasks like running, jumping, and flying. Share your creations with friends.

Use joints, bones and muscles to build creatures that are only limited by your imagination. Watch how the combination of neural networks and an evolutionary algorithm can enable your creatures to learn and improve at their given tasks all on their own. The tasks include running, jumping, climbing and flying. Can you design the ultimate creature that is good at all of the tasks? The latest update allows you to easily share your simulation saves and creature designs with your friends. Note that this is more of a simulation than a game. There are no real objectives. But there is a lot to learn if you are interested in the basics of machine learning and neural networks. You can even look at the source code if you want. There is also a Mac & PC version available for download and a browser version for you to try out on the main project website (keiwando.com/evolution).

Verdict
The clearest difference is in-app purchases: Evolution at none against SimplePhysics's 2. Evolution also leads on chart position (#134 vs unranked). SimplePhysics's advantage is update cadence (every 3 weeks vs every 2 months) and price ($0.99 vs $1.99). On rating, review sentiment, ratings volume and ads 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
SimplePhysics costs $0.99 and Evolution $1.99 up front. SimplePhysics sells 2 one-off in-app purchases. Evolution asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.5 for SimplePhysics against 4.4 for Evolution. Both are backed by a comparable volume of ratings — 242 and 549 respectively. Written reviews split almost evenly too, at 85% and 84% positive.
SimplePhysics ships an update every 3 weeks, Evolution every 2 months. Both last shipped on October 6, 2026.
