# ClusterSum vs When It Clicks

The clearest difference is in-app purchases: When It Clicks at none against ClusterSum's 10. When It Clicks also leads on iOS requirement (13.0 vs 16.0). ClusterSum's advantage is ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. ClusterSum sells 10 one-off in-app purchases. When It Clicks asks for nothing beyond the download.
