The iPhone Calculator Has a Backspace Feature You May Not Be Using

Maybe you’ve been there: You’re using your iPhone’s calculator to solve a sophisticated math equation (or calculate the tip on your dinner bill) when your thumb hits the wrong key. If you’re like many iPhone owners, your first instinct may be to hit “C” and start over from scratch. But as The Next Web reports, there’s a better way.

On May 2, Twitter user CENSORED Dialogue revealed a trick that, based on the viral response, is a game-changer for many people with iPhones. The video below demonstrates how deleting numbers one digit at a time in the calculator app can be done by swiping a finger across the numbers themselves. One horizontal swipe to the left or the right acts as a backspace button for the most recent digit, another swipe removes the digit before that, and so on.

The feature has been a part of the calculator app for at least five years, but unless you knew about it already or discovered it accidentally it’s easy to miss. iPhone users may also be surprised to learn of other hidden tricks that could improve the way they text, email, and conserve battery life. Follow the Apple Support Twitter page to keep tabs on any features you may not be taking advantage of.

Stop Your Snoring and Track Your Sleep With a Wi-Fi Smart Pillow

Everyone could use a better night's rest. The CDC says that only 66 percent of American adults get as much sleep as they should, so if you're spending plenty of time in bed but mostly tossing and turning (or trying to block out your partner's snores), it may be time to smarten up your sleep accessories. As TechCrunch reports, the ZEEQ Smart Pillow improves your sleeping schedule in a multitude of ways, whether you're looking to quiet your snores or need a soothing lullaby to rock you to sleep.

After a successful Kickstarter in 2016, the product is now on sale and ready to get you snoozing. If you're a snorer, the pillow has a microphone designed to listen to the sound of your snores and softly vibrate so that you shift positions to a quieter pose. Accelerometers in the pillow let the sleep tracker know how much you're moving around at night, allowing it to record your sleep stages. Then, you can hook the pillow up to your Amazon Echo or Google Home so that you can have your favorite smart assistant read out the pillow's analysis of your sleep quality and snoring levels the next morning.

The pillow is also equipped with eight different wireless speakers that turn it into an extra-personal musical experience. You can listen to soothing music while you fall asleep, either connecting the pillow to your Spotify or Apple Music account on your phone via Bluetooth or using the built-in relaxation programs. You can even use it to listen to podcasts without disturbing your partner. You can set a timer to turn the music off after a certain period so you don't wake up in the middle of the night still listening to Serial.

And when it's time to wake up, the pillow will analyze your movements to wake you during your lightest sleep stage, again keeping the noise of an alarm from disturbing your partner.

The downside? Suddenly your pillow is just another device with a battery that needs to charge. And forget about using it in a place without Wi-Fi.

The ZEEQ Smart Pillow currently costs $200.

Learn to Tie a Tie in Less Than 2 Minutes

For most men—and Avril Lavigne-imitators—learning to tie a tie is an essential sartorial skill. Digg spotted this video showing how you can tie one the simple way, with a tabletop method that works just as well if you’re going to wear the tie yourself or if you're tying it together for someone else who doesn't share your skills.

The whole technique is definitely easier to master while watching the video below, but here's a short rundown: As laid out by the lifehack YouTube channel DaveHax, the method requires you to lay the tie out on a table, folded in half as if you're about to loop it around your neck.

With the back of the tie facing up, you loop over each end, then twist the thinner of the two loops around itself so it ends up looking like a mini-tie knot itself. You'll end up nestling the two loops together and snaking the thin tail of the tie through the whole thing. Then, essentially all you have to do is pull, and you can adjust the tie as you otherwise would to put it over your head.

Unfortunately, this won't teach you how to master the art of more complicated neckwear styles like the fancier Balthus knot or even a bow tie, but it's a pretty good start for those who have yet to figure out even the simplest tie fashions.
