Gabi reimagines Facebook with a gorgeous design and custom filters, but it ultimately lacks nuance in highlighting the content people want to see. It replaces the usual Facebook feed with a selection of over 100 questions -- such as "Which of my friends' statuses are most liked?" -- that are answered in ranked lists from which you can do the usual Facebook interactions, with an option to limit results to today, this week, or anytime.

The unofficial Facebook option is a joy to navigate and explore. The top result in each list is shown in a box on the main screen in one of three color-coded rows -- "newest" for recent content, "me" for your own contributions, and "friends" for mining information about pals. While some preview images are clear and crisp, many -- especially within the lists -- are blurry and low-resolution. Swiping up or down on a box deletes it from view.

The problem is that Gabi wholly misunderstands the power play of Facebook interactions. You may have a morbid curiosity in the most popular content shared by friends, but you probably only have genuine interest in what a small subset of them are sharing. Facebook gets this, and that's why the official app and website push content from the people you interact with most straight to the top.

Gabi offers no such algorithm. It doesn't care whether you like one person's content more than another's; it just spits out the stuff with the most likes or comments. And it's because of this that Gabi does not work as a replacement for the official Facebook app; rather, it's a complementary app that only succeeds in certain tasks. Ultimately, Gabi is more beauty than brains.

The bottom line. Gabi's slick interface and attractive design make Facebook spring to life, but they cannot save it from the flawed premise of filtering only by popularity.
