"Stamps." is an app for people who collect station stamps and commemorative stamps. Record and share the places where you've stamped, and browse your full collection anytime on My Page. I made this app because I wanted to share the joy and sense of accomplishment that comes with collecting stamps. Analog stamps are especially charming — everyone presses them a little differently, arranges them in their own way, and even stamp books end up reflecting each person's personality. I'm planning to keep making the app easier and more fun to use. If anything comes to mind, feel free to reach out anytime.

Verdict
The clearest difference is device support: Stamps. at 3 against いろは's 1. Stamps. also leads on iOS requirement (15.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.
