# COSMOS vs RealTime Space

The clearest difference is iOS requirement: COSMOS at 13.0 against RealTime Space's 26.0. On price, ads, in-app purchases and device support there is nothing between them.

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