In the case of Apple Watch v. Fitbit, the winner comes down to the judge at hand. Apple currently offers two smartwatches — the Series 5 and the Series 3 — while Fitbit offers three models — the Fitbit Versa 2, Fitbit Ionic, and Fitbit Versa Lite. Whatever your assumptions about these devices are, throw them out the window, as each has something unique to bring to the table.
The USB Rubber Ducky is a famous attack tool that looks like a USB flash drive but acts like a keyboard when plugged into any unlocked device. The Ducky Script language used to control it is simple and powerful, and it works with Arduino and can run on boards like the ultra-cheap Digispark board.
Thanks to its encrypted messaging, WhatsApp can be a platform for secure communication with friends and family. One drawback, however, is that the app would let anyone add you to a group chat, regardless of if you approved it or not. This lack of control over your own account is over, as WhatsApp now lets you decide who can add you to a group chat.
Thanks to augmented reality, fashion companies can let customers try on cosmetics, clothes, more cosmetics, and sunglasses from the comfort of their homes and through the non-judgmental eyes of their smartphone camera.
It looks like Apple is finally going to do something to address all of the complaints about their unremovable stock apps clogging up people's home screens. While bloatware is a bigger problem on Android where you have to deal with apps from Google and carriers, an iPhone can still get pretty cluttered with all those stock Apple apps. I mean, just look at all this crap... AppAdvice noticed two new keys in the iTunes metadata that strongly suggest that you'll be able to get rid of stock apps on...
Microsoft announced Wednesday morning that it has entered into an agreement to acquire SwiftKey, makers of the SwiftKey predictive keyboard and its SDK that runs on over 300 million Android and iOS smartphones, for about $250 million.
Adjusting the brightness on your Android device is a simple but highly utilized action. For the most part, aside from the Sprint LG G3 variant, the brightness slider can be conveniently found nestled in your notification panel. And though it is easy to access, there is a small drawback to this feature.
As soon as you plug a set of headphones into a Samsung Galaxy series device, a bar pops up in the notification tray that lets you select from a list of "recommended apps" for earphones. It's a convenient little feature that shows the apps you're most likely to use based on previous activity.
One of my least favorite tasks is crouching in front of the kitchen oven or gas heater, and burning my fingers as I try to restart the pilot light with regular matches. I end up cursing the fact that I don't own extra-long matches or a stove lighter, but then I never go out and buy them, even though I know this issue will come up again. What can I say? I'm cheap. Now, instead of risking life, limb, and burned fingertips to reignite your pilot light or to kindle the wick on hard-to-reach candl...
I like to hop between apps pretty often, and luckily my Samsung Galaxy S3 let's me do that fairly quickly. By simply holding the Home button for a few seconds, it will bring up my most recent apps, and I can switch between them with a simple tap. So if I am playing Injustice: Gods Among Us and want to switch the song currently playing on Pandora, I can bring up the recent apps menu to navigate there. While this default app switcher is more than adequate, it takes up the entire screen and coul...
This year marks the first for Apple to exclude the Home button from any new iPhones. If you're going from a Home-button iPhone to a new XS, XS Max, or XR, you might be a bit stumped when trying to perform basic tasks, such as activating Siri. While you can't hold down the Home button any longer, there's a new method that's just as quick.
Last week, the internet was ablaze with talk about the Galaxy S8's home button, because it subtly changes positions without the phone alerting you. This feature was included to stop burn-in issues with the screen, and the general consensus from tech sites was the screens would not experience any burn-in at all.
Chopping veggies is pretty straightforward: grab the right knife and start slicing. Nothing to it! However, the way you cut your food does affect the length of time it takes to cook, as well as how evenly it cooks. So the next time you need to get your vegetable from hard and crunchy to perfectly soft in mere minutes, give the oblique cut a try.
We've all been there—you're away from home, your phone's battery is quickly nearing zero, and you forgot to bring your charger. "Hey, does anybody have an iPhone charger?" you ask. Crickets. If you could understand cricket-speak, you'd know that they too were saying "Sorry, bud. We're all on Android."
I spend a lot of time helping friends and family with their tech problems, like clearing a browser's cache, scanning a Windows computer for malware, and speeding up a Mac. However, the issue I deal with most frequently revolves around forgotten network passwords.
We've previously covered an app called YouTube Floating Popup Player which let you watch YouTube videos anywhere on your Android device, but it has since been removed from the Google Play Store due to infringement of certain policies.
With Android 5.0, Google introduced a new "Heads Up" notification system for incoming calls and messages. While the new incoming call interface seems to be a rousing success, the rest of the Heads Up system has been met with much less enthusiasm from users.
If there's one gripe I have with Android Lollipop, it's the new volume menu. When Priority mode was introduced, the stock volume panel was revamped to accommodate it, and somewhere along the way a bit of functionality was lost.
While it's currently impossible to go back in time, there is something wonderful about being able to undo the stupid stuff that you just did. While this is only really possible in the digital world, it does save you from real-life repercussions. If you've ever sent an email to the wrong person or sent some not-so-genius text messages, you know exactly what I'm talking about.
As it is right now, you can only send 5 images by email at the same time from your Camera Roll in iOS 7. There are some workarounds to increase that number, but a new feature in iOS 8 is finally making them unnecessary.
Many of our everyday apps include a menu tab or search bar, like Chrome and Twitter. In fact, a lot of times those are the first things we go for, as search is universal in most apps, and app settings are just about always accessible through the menu.
Log in to your LinkedIn profile, and you'll immediately be prompted to check out who's peeked at your profile. With one click, you can discover how many recruiters, companies, and random people have viewed your online resume.
Obviously this is just a teaser, and who knows how soon we'll see something like this in real life, but just go ahead and watch the video first before you continue reading.
Samsung's Galaxy series of devices have one common design theme that ties them all together—the physical home button at the bottom of the phone. This button can wake the phone, take you to your home screen, and even scan your fingerprint to securely unlock your device.
A good chef's knife is a thing of beauty and, with proper care, a joy forever. It can totally change the way you cook and turn even the dullest prep work into a glee-filled task.
The Galaxy S6 might just be the best Android phone on the market right now. From a hardware standpoint, Samsung truly knocked this one out of the park with its finely-crafted build quality and amazing screen.
When streaming services like Spotify or Pandora compete for customers, the main differentiating factor is the size of their libraries. While these and comparable services usually run somewhere around $10 per month, a completely free alternative may actually have the most expansive library out there.
So, you're scanning the internet for some cool articles to read during your lunch break and you come across something pretty interesting—"The 50 Most Incredible Things Every Person with a Brain Should Know." That sounds interesting, so you click, and boom, you are hit with the utterly obnoxious Page 1 of 50. Really?
Great ideas often strike at random times, but messaging friends and loved ones at an inopportune hour not only risks their wrath, but also increases the chances of your message not being paid proper attention to. Thankfully, there's an app that lets you create and post WhatsApp messages at the time you wish for maximum effect.
The OnePlus 5T was just released, and it's packing several new useful features. While many OnePlus 5 buyers are feeling frustrated with the quick release cycle, lots of fans are still clamoring to buy the new device. Aside from the larger screen, most of the buzz around the 5T has centered around the new face unlock method. Thanks to a clever hack, you can now get this feature on almost any phone!
If you own a Pixel or Nexus device, Project Fi is a great alternative for cellular service outside of the four major US carriers. Project Fi is a Google-managed MVNO, providing service primarily through the T-Mobile and Sprint networks. One of the biggest mysteries on Fi is which network you're connected to at any given time, but there's a simple solution.
When I booted up my second Sega Forever title, I wasn't sure what to expect. Sonic 1 was fun, but the controls weren't great. Touch screen controls can be excellent when the game is designed for them, but retrofitting a game designed for a physical controller to be played on a smartphone, well, sometimes is a bit disastrous.
We fight cancer in a variety of ways, but no matter whether drugs, biologics, or our immune cells are part of the battle, they can do a better job fighting back cancer if we can help them find the tumors.
An outbreak of anthrax from contaminated meat in Tanzania sickened dozens of people and moves the danger of this deadly bacteria back into focus.
The largest and arguably most widely known event of its type, especially in the US, the Sundance Film Festival is an annual celebration of independent film—ones made outside the Hollywood system. This year, a new type of experience appeared at the Sundance Film Festival in an installation called "The Journey to the Center of the Natural Machine." This mixed reality presentation offered the user the newest type of storytelling in a long and important line—continuation of the species kind of im...
