Prefectures is a very simple app with one sole purpose — track which prefectures of Japan you've been to. That's all it does. It does it pretty well.

Verdict
The clearest difference is update cadence: Prefectures at daily against airmates's every 2 months. airmates's advantage is device support (3 vs 1) and iOS requirement (11.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.
