Looking for a breathalyzer that’s small enough to fit in your pocket? Consider the Alchohoot. It uses an FDA-registered fuel cell sensor, which is the same technology used by police and military devices. The folks at Alcohoot were kind enough to send us a review unit so we could go hands on with this portable breathalyzer. Operation is very simple. Just extend the retractable plug from the Alcohoot device, and then plug it right into your smartphone’s headphone jack. The device works with iPhones, and many Android devices running Android 4.0+. A nice feature is the in-app timer…

Echo / Getty Images While we all know what cell phones are, we don’t always know how to differentiate them from smartphones. Here’s how. Smartphones Have a Mobile Operating System You can think of a smartphone like a miniature computer that can also place and receive calls. Though there lacks an industry-standard definition of a smartphone, the simplest way to tell a cell phone apart from a smartphone is to determine whether or not the device has a mobile operating system . A mobile operating system is much like what’s powering your personal computer at home or at work. In the…

As has been the case for several years now, I m confident that we have a pretty good idea of what the iPhone 7 is going to bring to the table, thanks to all the leaked photos, reports from people in the know , and supply chain chatter. Here, in as concise a form as possible, is what we expect from the iPhone 7: The form-factor is going to be identical - or near identical - to the iPhone 6S/6S Plus The headphone jack is gone Stereo speaker The antenna bands on the rear of the case have been redesigned Dual-lens camera for the iPhone 7 Plus Faster processor Some reports point…

The Pixel strikes a terrific balance between speed and beauty, ergonomics and straight-up usability. It s the purest vehicle for Android Nougat 7.0, Google s mobile operating system. It s a relatively quick-charger. And it offers the most seamless integration with Google s Daydream View VR headset (though the list of compatible phones continues to grow). Of course, the Pixel isn t perfect; the rear panel s glass treatment may be an aesthetic misfire for some, and it s vulnerable to cracking. It s also not as water-resistant as others, and though its camera is superb, the iPhone…

Earlier today, Apple launched its iPhone 7 series, including the iPhone 7 and iPhone 7 Plus. The phones are no longer twin devices. A critical iPhone feature has been significantly improved: the camera. The camera in the iPhone 7 is better than any iPhone before it, according to Apple, and then comes the iPhone 7 Plus. One of the best new features of the iPhone 7 and iPhone 7 Plus cameras is the image signal processor (ISP) that Apple built into that powerful A10 Fusion chip. Whenever you take a photo or video, the ISP powers over 100 billion operations and uses deep machine…

If we were still looking for evidence that smartphones have officially become a commodity, the line of ruggedized devices from iconic heavy equipment maker Caterpillar might just be that proof. We reviewed the Cat S40 Android phone to see if it offers a unique take on a rough and tough device or if it s just another phone with an unlikely brand name slapped on the back. Caterpillar is a name that s synonymous with construction, big projects and big gear, so it s not surprising that the major selling points of the S40 include its ability to stand up to the kind of conditions…

Released in September 2014, the Apple iPhone 6 changed the face of the smartphone industry. It was an update to a larger form factor of 5.44 x 2.64 x 0.27 inches compared to the iPhone 5s, thanks mainly to an increase in screen size from 4-inches to 4.7-inches. This exciting new iteration in phone design laid the groundwork for the iPhone 6s, and represented an improvement in almost every way over its predecessor. While newer models have superseded the specifications of the 6s, it remains an excellent phone, and it is still readily available in new and used condition from sellers…
