# SimplePhysics vs Evolution

The clearest difference is in-app purchases: Evolution at none against SimplePhysics's 2. Evolution also leads on chart position (#150 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.

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.
