Users appreciate the app's concept of helping foreigners manage their garbage disposal but report significant issues including limited municipality coverage, incomplete English translations, and outdated UI design. Many cities and districts are not included, preventing usage in some areas.

It suddenly stopped working, asking me the city, municipality and district. Toyonaka, Osaka City doesn't show the district, thus I can't use this app anymore.
