# Ikodoku vs Chain 3!

The clearest difference is ads: Ikodoku at none against Chain 3!'s shown. Ikodoku also leads on rating (5.0 vs 4.6). Chain 3!'s advantage is ratings volume (3.7K vs 1) and iOS requirement (13.0 vs 15.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.
