The project has been in development for a long time due to my job and incomplete front-end skills, which are not high-level. Although the released version has many bugs, I hope to receive feedback and improve my skills. As a single person, I am responsible for the back-end development, API analysis for App Store, and the entire app's development. Therefore, there may be many issues. In the future, I plan to release the source code and open up the API for companies to test and analyze competitors.

Currently, the app allows users to purchase any historical versions of the app, which is convenient for testing and comparing competitors. Additionally, it supports managing multiple countries' Apple IDs, making it convenient for international product testing.

The use process is as follows:

1. Use the invitation code to register: visit https://dogebless.me/
2. Apply for a free US Apple ID and set it up:
3. Log in to the App Store with the ID and download any app:
4. Exit the ID and search for the app to download:
5. Purchase the desired version and view the order status:
6. Click install to install Ad-hoc:
7. Go to the desktop and run the app:

Important Use Notes:
- The app does not support two-factor authentication. If prompted to upgrade, do not upgrade.
- Do not log in to the ID in the settings.
