Hey friends myself Govind Sable and im going to explain why this app is useful to me. There are some apps or games for android that are not available on the playstore, but you can download such apps or games from the internet. There are few games that are separated into apk file and data file. Apk file is same for almost every device but data files are different according to different types of GPU RENDERER like mali, adreno etc of device ( mine is adreno) in which you are installing app or game. For installing such a app or game you must know what type of GPU renderer is installed on your device and you must download the same, if you download data files other than your gpu renderer, such a app or game will not run on your device. There is only ONE way to know gpu renderer of device and that is CPU-Z. Thanks for reading this.
