Tracking parcels for USPS is an Android application designed for automatic tracking of parcels and letters sent via the US Postal Service. Developed by empirical.me, this free app is a great alternative to the official USPS app, with a different UI and a different set of features.

The app offers automatic checking of status and notifications when the status changes. It also allows scanning of tracking numbers, showing the number of days in transit, and sorting parcels. The app's material design makes it easy to use and visually appealing. Additionally, it contains a cute widget for the home screen.

It is important to note that this is not an official USPS application, and the developer is not related to the organization in any way. If you encounter any errors or hang-ups, you can contact the developer via email with a full description of the issue, including your device model, Android version, and how to reproduce it. The developer also welcomes your ideas, questions, and concerns.
