Many people say they want to get fit, but what does this actually mean? Fit for what?

The websites of leading fitness trackers, like Apple Watch, Fitbit, Microsoft Band and Jawbone Up don’t shed much light on this question. They talk a lot about the things that their devices measure, and even suggest changes in how we go about our day, but they rarely explain why this matters or what the actual benefits are.

In the business world, Apple entering your product category is a little bit like a tsunami crashing into a home aquarium. What had previously seemed like a nice, small and self-contained ecosystem suddenly runs the risk of being obliterated by a giant wave-maker.

When Tim Cook announced the Apple Watch at Apple’s recent media event, the crowd went wild. But exciting as it was for consumers, it represents a seismic shift for the currently $330 million wearable tech industry.

Devices that can serve up smartphone notifications, track fitness goals and even advise us on health matters have the potential to be huge — but they’re not yet. That’s about to change, according to Juniper Research, which forecasts that wearable devices like smartwatches could hit sales of $19 billion by 2018.

What happens to Apple’s marketplace rivals as this sea change takes place? Cult of Mac did some digging to find out how companies like Jawbone and Fitbit plan to survive Apple’s smartwatch revolution.

Apple relies heavily on caffeine. A recent company job listing advertised a role for an iCup technician, with the important task of providing “a fresh brew coffee to all Apple employees within their department.”

Jony Ive’s design team is especially obsessed with the black stuff: For years they kept a $3,000-plus Italian Grimac espresso machine, despite the fact that it leaked all the time. For a while in the 1990s, the design team was even mockingly dubbed “Espresso” for their unabashed love of caffeine culture.

Apple’s not alone in its coffee snob behavior. The rise of coffee shops — with seemingly hundreds of variations on the old coffee standards — have infiltrated every city across the United States: Americans spend $18 billion per year on specialty coffee alone.

But how much do we actually know about it?

This may be the last time you feel good about walking half a mile to get a cronut: a calorie-counting food scale and fitness tracker are on to you.

Smart food scale Prep Pad now synchs with Jawbone Up, keeping track of what you’re eating and how many calories you are burning.

It’s latest buddy system in the quantified self movement, where, as we reported earlier, your car is already conversing with your fitness tracker about how much you should be hoofing it instead of driving. Sales of fitness gadgets like the Jawbone Up, Fitbit and Nike + are over the previous year, leaving us with 19 million trackers and trainers strapped to our wrists.

Today, Apple unveiled not one, but two new iPhone 5 models, the 5c with its colorful backing and lower price, and the flagship iPhone 5s, with amazing technology like a fingerprint sensor and motion-sensing co-processor.

It’s all very exciting, of course, unless you happen to be one of makers of technology that is now rendered obsolete, or at least severely relegated to a niche market.

Here’s a quick look at several things that Apple has leapfrogged with its new announcements.

Apple is becoming a victim of its own success. It’s been several years since the company launched the iPad and revolutionized yet another product category, but we haven’t seen anything truly groundbreaking since then. Sure, we’ve had the iPad mini, the Retina MacBook Pro, and the awesome new iMac, but they’re all variations or improvements on existing products.

Now the world is clamoring for something completely new — something that’ll take off just like the iPod, iPhone and iPad.

Some reports suggest it will be the Apple “iTV,” the company first television set, which is said to be in development inside the company’s Cupertino headquarters. But it’s more likely that Apple’s immediate concern is with the “iWatch,” a smartwatch powered by iOS that will bring all kinds of crazy-cool technology to your wrist.

I had suspicions Apple might be working on its own watch when it redesigned the iPod nano last year. A lot of fans used the tiny nano as a watch thanks to third-party strap accessories, and it seemed like its form factor and design were changed for a reason — to make way for something new.

We’ve been reading iWatch rumors for the past few months, so it’s time to put them all together and establish what we think we know about the iWatch so far.

It’s taken well over a year, but the Jawbone UP finally has an official companion app in Google Play. The device has only been compatible with iOS devices since it launched in November 2011, but now you can track your sleep and physical activity on Android-powered smartphones, too.

Furthermore, starting today, UP will be available in Apple stores across Europe.

The Jawbone UP wristband first launched back in 2011, and it became quite a popular product. Everyone wanted to get their hands on the fitness- and sleep-tracking iPhone accessory, which came with plenty of promise. Unfortunately, it launched with all kinds of problems, too — including water leaks and inflexible components that broke too easily — and Jawbone was forced to pull it.

The company’s now giving the device a second shot. Today it announced the second-generation Jawbone UP, which is now shipping for $129.99.

Jawbone has pulled its newly-released UP health band and offered a “no questions asked” guarantee that customers can get a full refund and keep the product.

In an official statement Jawbone CEO Hosain Rahman says “We recognize that this product has not yet lived up to everyone’s expectations – including our own – so we’re taking action.”
