Verdict

The call

The clearest difference is ratings volume: OpenCat at 852 against AIトーク Chat Bot's 25. OpenCat also leads on rating (4.6 vs 4.4). AIトーク Chat Bot's advantage is update cadence (every 2 days vs weekly) and iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
