# Systems vs Scan Spark

The clearest difference is iOS requirement: Scan Spark at 18.6 against Systems's 26.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Systems sells 4 in-app purchases, starting at $3.99 per 7 days and Scan Spark sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
