‘Knock’ Lets You Securely Unlock Your Mac By Pounding Your iPhone Screen

Typing in your password every time you want to unlock your Mac sucks. Apple still hasn’t added facial ID recognition to OS X, nor have we heard nary a mention of Touch ID coming to MacBooks, but if you’re looking for a neat way to quickly unlock your Mac, a new app called Knock allows you do it with two quick taps on your iPhone screen.

The free Mac app works in tandem with an iPhone app that turns your phone into an authentication device. Knock uses Bluetooth Low Energy to communicate from iPhone to Mac but you should be able to leave it on all day without draining battery.

Here’s a video of Knock in action:

The Buzzy Vybe Smart Bracelet May More Annoying Than Your Little Brother

The people behind Vybe are calling it a “smart bracelet,” because it’s missing a key element included in all smartwatches: the screen. Instead of relaying information through a display, Vybe vibrates, nagging you to look at your phone.

A device that repeatedly requires halting your current activity seems to defeat its own purpose — namely, untethering you from your phone. It’s also strange that Vybe’s promotional clip suggests you pick up your phone while driving, which is illegal in many states — including California, where WearVybe, the bracelet’s maker, is based.

You’ll Never Lose Your Keys, iPhone Or Kid Again If You Buy The HipKey [Review]

The HipKey: never lose your keys (or iPhone) again.
The HipKey: never lose your keys (or iPhone) again.

This is what I wrote earlier this month, strung out on CES and showing it at the edges:

“With irritating regularity, my girlfriend and I dance the same dance. She, or I, go to bed with our iPhones. She, or I, lose it somewhere within the ocean of the bedfolds. She, or I, find ourselves apoplectic. She, or I, demands that the other calls the phone to locate. And then she, or I, realize that we’ve lost our phone too. And then we murder each other into a spattering of bloody chunks in our festering rage, somehow to reconstitute ourselves, temporarily find our iPhones and begin this amphisbaena dance anew.”

The guys behind HipKey, a keychain dongle that can track your iPhone (and vice versa), were paying attention, and so they sent me over a unit for review. I’m not sure it’s revolutionized my life, but it sure has simplified it: now, instead of constantly worrying about misplacing my keys or my iPhone, I only have to worry about misplacing both at the same time.
