UPSM is a feature of some Samsung Galaxy devices like the Galaxy S5, Galaxy Note 4, etc. but it only supports a limited number of apps. This app serves to add more supported apps with ease. This app only works on the mentioned compatible devices and requires root access which means your device must be rooted. Please note that this app only adds selected apps to the list which is read by the UPSM framework and has nothing to do with how the ultra power saving mode feature works. It may be possible that some apps does not work in UPSM or may have some issues working in UPSM so please know that this app has nothing to do with that. Please do not make a one star rating just because the app does not seem to work on your device. It would be better if you email me your issues or problems with the app so I can try to help you solve the issue or help you understand how the app works.
