Android application package whose Chinese title translates roughly as a body-shaping or fitness app, marked VIP, about 21.5 MB. It is not repair documentation and contains no schematic, boardview or firmware data. APK files install on Android phones, tablets or TV boxes and can be inspected with tools such as APKTool or jadx. Modified VIP builds from unofficial sources may carry unwanted code, so scan the file and avoid installing it on devices that hold personal accounts.
