All the cool kids are doing it. (As in, Savannah Guthrie and Wrangler.)

Now, we want in.

If you haven't seen a #2015BestNIne post on Instagram yet, you will before the year's up. So — today!

The collage-style post, which has seen over 1 million hashtag mentions on the photo-sharing platform, is created using a web-based app, 2015 Best Nine. When you type your Instagram handle into the interface, you're presented with a fancy collage featuring nine of the top "liked" photos from your personal profile.

And the fun doesn't stop there: The app also clues you into the total number of likes you accumulated in 2015. For the Insta-obsessed among you, that's a pretty mind-blowing statistic. Get ready to pat yourself on the back.

But try not to compare yourself to socially-savvy celebs. Justin Bieber and Kylie Jenner racked up a whopping 1 billion likes each.

Still, it's fun to see which of our photos resonated with family and friends. Check out the app here.
