# RadSim vs Rad Index

The clearest difference is iOS requirement: RadSim at 13.0 against Rad Index's 15.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. RadSim sells 1 one-off in-app purchase and Rad Index sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
