# Quantum Grid vs AstroForge

The clearest difference is iOS requirement: AstroForge at 15.0 against Quantum Grid's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Quantum Grid sells 1 one-off in-app purchase and AstroForge sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
