Open Instagram, Airbnb, Apple Music, Twitter, Dropbox or Lyft and at first glance it might feel like it's hard to tell the difference between which app is which: big, bold headlines with rounded serif fonts; minimal black and white interfaces with lots of negative space; little to no color.

The modern interface style feels so bare-bones. Ironically, many of the most popular apps feel like they're actually not designed at all.

What happened to the Instagram dark-blue header? Where did the bright pink colors in Lyft's app go? Did the biggest technology brands forget about their branding? Or are they all just sharing the same templates?

What's more, there are clear signals that Google is also joining the colorless trend. This year, Google is pushing out a major revamp to its Material Design guidelines, and the announcement came with a preview of a redesigned Gmail.

And guess what? It looks exactly like everyone else. Most of its trademark red UI elements have completely vanished (like the red top bar) and we get a lot more white: a white bottom bar, white floating action buttons, white input fields and a white background.

We all know Silicon Valley has a tendency to steal ideas from each other, but for the last decade (at least) design has always been the key to differentiation. This trend in design uniformity seems very counterintuitive.

So what is exactly is going on?

Well, I'd argue that the uniformity in product design is a good thing. And here's a few reasons why.

More Focus On Content and Outcomes

App fatigue is a real thing. Most people have grown tired of bouncing between too many apps or learning how to use a new interface after every new download.

Close to a quarter of all downloaded apps are deleted after just one use. Research shows that most people have just a few apps they use on a regular basis--apps that save time or money (or both) and make life easier. With uniformity across everyday digital products, designers can put more focus on doing exactly that.

As Don Norman--known for coining the term "UX"-- said it best, "The real problem with the interface is that it is an interface. Interfaces get in the way. I don't want to focus my energies on an interface. I want to focus on the job."

More Consistency Means Better Usability

When was the last time you tried to buy something online and didn't immediately scan the top right of your screen to get to your shopping cart? The standardized design conventions of nearly all e-commerce sites means people don't need to relearn how to shop at every online store.

Anything that is a convention on a majority of apps will be burned into most people's brains and deviation unfortunately causes confusion and frustration.

Take Snapchat, for instance, which released a controversial design update earlier this year. The unconventional design--which included jumbling features and changing the navigation patterns--caused user sentiment to drop 73 percent almost immediately, and the app's user count and share price fell way down.

Granted, designing something novel is risky, as Snapchat proved, but consistent design (even among competitor apps) can reduce the likelihood of upsetting your users.

Branding Isn't Just How It Looks, but How It Works

Reconciling a user's needs and intentions with a solution is where great experiences are derived. A differentiated experience is intangible and arguably much more valuable to a brand than a differentiated look and feel.

Granted, style is important, and it can also play a big role in the experience. People are more tolerant and forgiving of a confusing interface when they find it visually appealing.

But a designer's energy should be spent on creating the best possible way that someone can complete a task, not finessing color palettes or dramatic animations. Designing something well, something valuable to the end-user, requires a seemingly infinite cycle of testing and iterating designs to get closer to what is useful and usable.

With interface designs trending towards consolidation, designers can spend less time worrying about what color or how big a button should be and more about why it should be there in the first place.

Sameness in Interface Design Does Not Stifle Creativity

Now, I know what you're thinking--and yes, the downside to all of your favorite apps looking the same is that there's less creativity and innovation. Which, honestly, I think is true.

But even if every product designer joins the movement for stripped down interfaces, there's still plenty of meaningful design work to be done.

In fact, the truth is, sameness in design is beneficial for the near-term (hopefully I've made the case for why), but they have even greater implications for the long-term business benefits.

For one, the rise in augmented reality and artificial intelligence, our interactions with computers will become more likely to be invisible; screens are shrinking, gestures are becoming more familiar, and we're talking or chatting with computers now more than ever.

That said, there will be even more opportunity to engage the senses (beyond visuals), attention, emotions or perceptions.
