This beautifully designed 'dumb phone' can only make calls and send texts - and it might be the key to curing our addiction to apps

Hollier and Tang met in 2014 when they were asked to design smartphone apps at a Google incubator. But Hollier and Tang agreed that the world had enough addicting apps and decided to design a phone intended to be used as little as possible.

Even back in 2014, Hollier and Tang were onto something.

Recent data from analytics firm Flurry pegged daily smartphone use among people in the US at five hours per day. Another study, this one from tech support firm Asurion, says Americans check their phones 80 times each day on average.

Most of that constant use is thanks for apps. Several of the most popular smartphone apps on the planet — like Instagram, Facebook, Twitter, and Snapchat — have been designed to use psychological tricks to continuously grab your attention.

At this point, even Silicon Valley parents — the ones often responsible for building these addictive apps and devices — are raising their kids to be tech-free.

Light launched its first product on Kickstarter in 2015. Called the Light Phone, it was only capable of making and receiving phone calls.

The Light Phone couldn't text, connect to Twitter, take photos, or send emails.

Hollier and Tang designed the phone as something of a security blanket for smartphone users — you could leave your smartphone at home and "go light" using only the Light Phone. People could still reach you, but you'd be forced to look up from your phone and experience the world around you.

The Light Phone wasn't just technical — it had a philosophical message. Hollier and Tang wanted to encourage users to consider the importance of disconnecting from the digital world.

"We are becoming scared of boredom, scared of solitude," Light's founders wrote in a blog post about how the company got its start.

Light's message must have clicked with like-minded customers — the company says it sold more than 10,000 Light Phones in more than 50 countries.

Now, Light is back with its second-generation phone — the Light Phone 2.

The Light Phone 2 is a more powerful version of the original device.

Light says it falls somewhere in between the original device and a smartphone. It isn't as basic as the first-generation phone, but it still doesn't have apps like a smartphone does.

"Light Phone 2 encourages you to spend more quality time doing the things you love most, free of distractions," Light said in an announcement for the new product. "Enjoy a morning jog, a drink with an old friend, a night on the town or day at the park with your kids, waking up with a coffee and a good book, a trip to the beach, or simply some time away from your Instagram."

The Light Phone's most important new feature is the ability to text.

The original Light Phone could only tell the time and make calls. But the Light Phone 2 can send and receive text messages, which will likely make it more enticing for users who are afraid to completely give up their smartphones.

The Light Phone 2 has also added an alarm clock, larger speaker, microphone and physical buttons.

Light says that the Light Phone 2 is easier to use than the original device, and could even be your only phone.

The original device was intended to be used as a companion to your smartphone. You could set up call forwarding through Light's computer app, then leave your smartphone at home for short periods of time.

But since the Light Phone 2 has more features, it could theoretically handle long-term, daily use. Light is hoping to target smartphone users who feel frustrated by the complexity of iPhone and Android devices.

Unlike the original phone, you'll be able to add contacts to the Light Phone 2, program it to call you a taxi, or use it to get simple directions.

The Light Phone 2 has 4G LTE connectivity and a USB-C charging port.

Plus, the phone has a headphone jack.

The Light Phone 2 has an E-Ink display and comes in black or white.

It's only 6.5 millimeters thick and about the same length and width as a credit card.

The Light Phone 2 will be able to slip into a shirt or pants pocket with no problem. Because of it's small, slim size, it even fits into some wallets.

You can pre-order the Light Phone 2 for $250 starting March 1.

The phone will eventually cost $400, but is available for the discounted price for the next 25 days of Light's Indiegogo campaign.

Light says the phone will start shipping in "early 2019."
