If you’re afraid of ever being in a dangerous situation without any witnesses or good samaritans nearby, you might want to consider downloading this new app appropriately named Witness. Calling itself the ‘panic button for the smartphone age,’ one tap broadcasts live video and your current location to a list of preset emergency contacts, who can then decide if it’s appropriate to take action.

Of course, if they do nothing, they could potentially have front-row seats to a very morbid and disturbing show.

Domino’s Pizza app update lets you keep your eyes on your pies

Domino's has added a couple cool features to its iOS app.

You know that feature when you order online from Domino’s that keeps you posted on the process of your order and even tells you which employee has put your pizza in the oven, and who just left the store to bring it to you?

I love that feature, for some reason. I don’t think it makes me some kind of creepy pizza stalker, if that’s even a thing.

But my main issue is that I had to keep my laptop open to stay on top of the whole process. Luckily, however, Domino’s has addressed that one, strangely specific gripe with the latest update to its mobile app.

Fitness app data shows which states are more unhealthy than yours

Which states are filling up these rings?

Smug Californians now have proof they’re better than you.

A couple of the most popular fitness apps in the App Store have pooled their data to figure out which U.S. states have the best (and worst) health habits. They examined a combination of workout and nutritional info among their users and concluded that the Golden State has the best habits, and Wyoming has a lot of work to do.

I typically look for two things in a hotel room: Internet included with the room and free breakfast. But a new hotel in London’s Covent Gardens might have me adding some things to that list.

The recently opened Hub hotel from Premier Inn, the U.K.’s largest lodging chain, sports some pretty impressive tech features that involve both smartphones and wearables like the Apple Watch. And while your hotel room shouldn’t be the coolest part of any trip, Premier is really giving the rest of your vacation something to live up to.

Apple Music could put a serious hurt on your iPhone battery

Harsh terms, but probably not illegal.

We’ve had a couple days to check out Apple Music, Apple’s song-streaming platform that launched Tuesday. It comes loaded with 30 million songs that you can listen to on demand with a quick search or a request to Siri.

But all that choice and tech power may come at a price, as some users are reporting that the new Music app is killing their iPhone’s battery life.
