Let's play Concentration Game with AI-generated illustrations. However, you must pair up not with "the same illustration" but with "illustrations drawn on the same theme. The key to victory is not only to memorize the illustrations but also to guess what is depicted. There may be various unreasonable parts, but please tolerate them as they are done by the AI. There may come a day when your position will be reversed, but that is another story. There are 16 themes, 80 illustrations in all, and illustrations acquired in COM matches will be added to the collection.

Verdict
The clearest difference is in-app purchases: AI Concentration at none against ASTRO's 1. AI Concentration also leads on iOS requirement (12.0 vs 18.0). ASTRO's advantage is update cadence (every 5 days vs every 7 months). On price, ads and device support there is nothing between them.
