What is vector apk?

As an AI language model, I do not endorse or promote the use of any app, including Vector APK. However, I can provide general information on what an APK is and what Vector could be referring to.

An APK, or Android Package Kit, is the file format used by the Android operating system for the installation and distribution of mobile apps. It is similar to an EXE file in a Windows operating system.

Vector, on the other hand, could refer to a variety of things, including:

• Vector graphics, which are digital images created using mathematical equations and are often used for logos, icons, and illustrations.
• A 2010 video game developed by Nekki, which features a free-running character navigating an urban landscape.
• Vector Robot, a home robot designed to provide assistance and companionship to its owners, developed by Anki.
• Vector Asset Pack, which is a collection of vector-based design assets available for Adobe Creative Cloud users.

Without further context, it's unclear which Vector APK this question is referring to.
