Hibernator is an incredibly useful app for optimizing the way your smartphone works quickly and easily.
Thanks to its interface's intelligent design, using Hibernator is very simple: from the main screen, you can see how much RAM your smartphone is using, as well as the apps that take up the most energy, even if they're running in the background. By tapping on the 'Zzz' icon, you can close all these apps automatically, saving precious battery life and improving your smartphone's performance by leaps and bounds.
The list of apps to close is totally customizable, and you can modify it whenever you want by adding or removing external apps as well as smartphone apps.
Hibernator is an especially useful tool for anyone with an older smartphone that no longer works quite as well as it did before.
