Welcome to Android Central! Yes, we would recommend uninstalling the app. Assuming you don't have an ancient version of Android, you should let the system manage RAM on its own. Android prefers RAM to be mostly full of open apps, which allows the user to open or switch apps quickly and efficiently. If you have an app that is constantly force-closing apps, the system will just reopen them, and this will set up an endless cycle of close-open-close-open that will use up battery.
