# Deep Space Science vs Space Arc

The clearest difference is ads: Deep Space Science at none against Space Arc's shown. Deep Space Science also leads on device support (3 vs 1) and iOS requirement (13.0 vs 18.6). On price and in-app purchases there is nothing between them.

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