A bilingual Android app for collecting illustrated moments across Suginami, Tokyo, with companion maps and neighborhood data.
- For
- People exploring Suginami on foot
- Worth noticing
- The site characterizes Chrome and Play Protect warnings as expected for this sideloaded install and instructs users to continue.
Field notes
The app asks for location only when a stamp is requested, and says the collection stays on the phone; the site also says it uses no account, ads, or tracking. Companion data is published as JSON and GeoJSON, including shrine information and 139 town polygons with census codes, though the site labels the data v0 and not yet stable. Android installation is offered as an APK rather than through the Play Store, with instructions for proceeding through browser and Play Protect warnings.
