# Unit Converter Engineering Pro vs PipeQ

The clearest difference is device support: Unit Converter Engineering Pro at 3 against PipeQ's 1. Unit Converter Engineering Pro also leads on iOS requirement (13.0 vs 18.6). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Unit Converter Engineering Pro sells 2 in-app purchases, starting at $5.99 per 7 days and PipeQ sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
