Google released their cloud connected note taking app. It was only a matter of time before a developer would pick the app apart and bring us an inverted version. Developer "fritzhy" has put together a flashable.zip. You will need to first uninstall any previous versions of Google Keep then simply place the inverted app on your sdcard, boot into custom recovery and flash. Apparently sync is working perfectly. For now the app has to be flashed in recovery to keep sync working. Grab this inverted app from the source link below.
