This is NOT the Greenify app itself, it is just a donation version with some experimental features. It works only if you have installed Greenify.=== Disclaimer ===
All these experimental features are in early stage, and may not work on all devices & ROMs (known incompatible with MIUI and Meizu Flyme). They are included only for advanced users with sufficient knowledge about what they really mean and how to correctly use them. These features may crash your apps, brick your phone, or even wipe your data in the extreme cases. I will try my best to avoid those situations, but I don't take responsibility about the possible consequences. For your safety, please do a NANDroid backup before activating these features.
It is safe to install this app, since nothing is affected before activating the experimental features explicitly.
=== Experimental Features ===
Note: Some features need Greenify v1.8 to work. All features will be activated / deactivated as a whole (I will separate them for activating later) and no options or setting UI at present.
◆ Boost mode
Android framework is patched to allow Greenify to perform hibernation without the traditional root routine, which is usually buggy (for some root tools) and slow.
◆ Allow (some) system apps to be greenified in Greenify
Android framework is patched to deprive system apps of immunity to hibernation.
Beware, most system apps are critical to the basic functionalities of your device, once greenified, you may lose some part of usability. If something bad happened, remove the system apps you recently greenified and reboot, or deactivate the experimental features of Greenify and reboot.
Currently, all core Android component whose package name starts with "com.android." are still not open for greenifying, but this might change in the future.
◆ Allow GCM push message to wake hibernated apps
Google service framework is patched to allow the GCM (Google Cloud Message, a.k.a. C2DM) broadcast to wake the hibernated apps, thus you can greenify some apps without losing the ability to receive push message.
Attention: Not all apps use GCM as push mechanism, some apps create their own TCP connection for push in background service, thus can't benefit from this patch. Their push messages can never survive hibernation, please DO NOT ask for that, it's just a "mission impossible" in technical way. Instead, ask their developer to adopt the more RAM-and-battery-friendly GCM push.
=== How to Activate ===
All these experimental features are implemented as modules in Xposed framework. You must install Xposed framework first to activate them. You can find "Greenify (Donation)" in the module list of XposedInstaller.
If you are not familiar with Xposed framework, please read this post (you can download it from there too):

=== Why do I need installing another framework for all these to work? ===
Since these experimental features all need OS level patches, traditionally they can only be applied with ROM modding, which is highly device-specific and ROM-exclusive. Xposed framework is a new hope to do finer grained tiny patches in a ROM-independent way. Thanks to Xposed framework, you can enjoy these experimental features of Greenify without replacing your ROM.
