# HHL algorithm vs Inception

The clearest difference is in-app purchases: HHL algorithm at none against Inception's 1. HHL algorithm also leads on ads (none vs shown). Inception's advantage is iOS requirement (13.0 vs 16.6). On price and device support there is nothing between them.

Both are free to download. Inception sells 1 one-off in-app purchase. HHL algorithm asks for nothing beyond the download.
