# Gram Scale vs DFS Optimizer

The clearest difference is iOS requirement: Gram Scale at 13.0 against DFS Optimizer's 16.6. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Gram Scale sells 2 in-app purchases, starting at $3.99 per 7 days and DFS Optimizer sells 5 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.
