# Radstep vs Kalos

The clearest difference is ads: Kalos at none against Radstep's shown. On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Radstep sells 17 in-app purchases, starting at $3.99 per 7 days and Kalos sells 1 in-app purchase, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
