# DSA Master vs GCP Test Sim

The clearest difference is iOS requirement: DSA Master at 16.2 against GCP Test Sim's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. DSA Master sells 1 one-off in-app purchase and GCP Test Sim sells 5 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.
