co-founder of streak here: streak works with both google apps and non apps accounts. We've noticed some of our early users using it for non business purposes as well (task management, event planning, etc).
I'm using it today for both and i like it.also, im blown away with snippets. the shortcuts to access them is genius too. i've now begun to remove clippings and other add-ons that i've used for this specific feature.
