# MapProjectionDemonstration vs entanglement entropy

The clearest difference is iOS requirement: MapProjectionDemonstration at 16.4 against entanglement entropy's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
