# ColorMetric vs Drop Test

The clearest difference is iOS requirement: Drop Test at 15.1 against ColorMetric's 17.0. On price and in-app purchases there is nothing between them.

Both are free to download. ColorMetric sells 1 in-app purchase, starting at $9.99 per year and Drop Test sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
