荷物配送追跡OKIPPA is a free Android app developed by Yper株式会社 that provides users with a centralized system to track their delivery packages. The app is designed to work in tandem with the OKIPPA bag, which is a special delivery bag for users to receive their packages. The app is equipped with automatic tracking features that allow users to track their packages from various delivery companies, including Yamato Transport, Japan Post, and Sagawa Express, among others. Users can also manually enter tracking numbers to track their packages.

荷物配送追跡OKIPPA also allows users to request redelivery of their packages from the app. Users can also purchase insurance for their OKIPPA bags and report theft directly from the app. The app is also integrated with popular e-commerce sites like Amazon, Rakuten, and Yahoo! Shopping, among others, to automatically track packages. The app is recommended for those who frequently shop online and want to manage their packages from one place, as well as those who want to reduce the burden on delivery workers by avoiding redelivery.
