Unless anyone knows another reason for this impressive increase in comments? Seems to roughly coincide with Sync launching. If thats the case, just goes to show the importance of good third party apps.

EDIT: Looks like a confusingly labeled graph and I think this is total comments. I have no idea why that spike could exist though.
The odd thing is, their screenshot is on the play store as well, you can see the logo next to installed apps. However, when I check on my phone, it matches yours.
Like @skye pointed out, I suspect it might indeed be based on region. I remember another thread where a user reported seeing Sync rated at 3 stars, whereas others reported 5 stars.
Might be region dependent?
