"iFeng UDID Lookup Assistant" is a professional iOS device UDID lookup tool, providing convenient services for developers and users.
The website offers one-click service to directly find the UDID of an iPhone, iPad, or iPod, and provides developers with an API to fetch the same data from client devices using a mobile browser (Safari), without the need for iTunes or a desktop/MacBook computer.
We created this tool for internal use in early 2013. Since then, we have received dozens of requests from other teams to share the technology and help their development and testing processes achieve this functionality. Therefore, udid.yhios.cn (formerly known as udid.yhios.cn) was made public in August 2023.
A device's UDID may be a critical requirement for iOS developers testing early versions of mobile applications, and it also helps in debugging and testing applications during early development iterations.
