# Codea vs Measurement Uncertainty GUM

The clearest difference is iOS requirement: Measurement Uncertainty GUM at 15.0 against Codea's 18.5. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Codea sells 3 in-app purchases, starting at $4.99 per month and Measurement Uncertainty GUM sells 2 in-app purchases, starting at $15.00 per month. Whichever you choose, the download price is not the number that matters.
