# Master SQL vs OpenAPI Viewer

The clearest difference is iOS requirement: OpenAPI Viewer at 18.1 against Master SQL's 26.2. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Master SQL sells 6 in-app purchases, starting at $4.99 per month and OpenAPI Viewer sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
