# Cycle Sync vs Code Red

The clearest difference is iOS requirement: Cycle Sync at 18.2 against Code Red's 26.5. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Cycle Sync sells 3 in-app purchases, starting at $4.99 per 7 days and Code Red sells 1 in-app purchase, starting at $19.99 per year. Whichever you choose, the download price is not the number that matters.
