ZIP and Cantons of Switzerland is a free Android app developed by Michaël Minelli that allows users to perform various operations on Swiss postal codes. The app is designed for travelers and residents alike and is available in German, French, Italian, and English. One of the app's main features is the ability to discover different cantons, search for localities by postal code, name, or address, and locate and display them on Google Maps.

The app also provides detailed information about the location and canton, including flags, the number of municipalities, and language information. Additionally, users can explore localities linked to their postal code and view cantons on Google Maps. Data from the Swiss Federal Statistical Office of population is provided in the app, with figures from 2013 being the most recent.

ZIP and Cantons of Switzerland offers speech recognition, a simple interface, and configurable options that are adapted to current design trends. The app does not require an internet connection for most operations, except for those relating to Google Maps. Users can remove advertising for 1.50 CHF through an in-app purchase.
