Comments on 2021 USPS Carrier Calendar for Android

★★★★★ Nice app for see what your days off are going to be. Notes have been added but not by day just month. Would be nice to have appointments on this calendar. But I understand it's a work in process. This is the best postal calendar app that I have seen.
★★★★★ I've bought this app for the last few years and found it really helpful. I always recommend it to my fellow carriers.
★★★★★ Love the new layout. I just wish the app would launch to the current calendar month when you open it instead of starting October 2020. Other than that it's great! I use it all the time to plan my vacations (and sick calls) 😉
★★☆☆☆ Dates are jacked up rendering it useless.
