# Interval Timer vs Shadowstep

The clearest difference is in-app purchases: Shadowstep at none against Interval Timer's 12. Shadowstep also leads on ads (none vs shown). Interval Timer's advantage is device support (4 vs 1). On price and iOS requirement there is nothing between them.

Both are free to download. Interval Timer sells 12 in-app purchases, starting at $2.09 per month. Shadowstep asks for nothing beyond the download.
