It used to be that when you got back from vacation, you’d drop your film off at the lab and cross your fingers. You hoped you’d get some half-decent photos back a week later, while memories of that cool restaurant you liked faded with your tan.

Now we share our photos with friends and family while we’re still on the beach, then forget about them. But we can, and probably should, make a little effort to preserve our vacation memories. And — you guessed it — there are apps for that.

Is it too late on a Saturday night to hit the hardware store for that essential dingus you need for Sunday’s DIY project? Has the local supermarket closed already, or do you still have time to buy some more beer? Does the Kanaan restaurant (“Best Humos in Berlin”) even open today? Just ask Siri.

You may be used to firing up Google Maps, searching for the store or restaurant you’re interested in, then tapping around in the app to get to the opening times. But did you know that Siri can also tell you if a local business is open, or when it will be?

You already have all the travel gadgets you need for a successful and relaxed trip. Today we’re going to look at travel apps. Specifically, apps that make your trip better and easier, like great city guides.

We’ll also showcase apps that work around limitations you face while traveling, like a lack of bandwidth. Let’s get started!

Using one-handed maps is currently suboptimal, because you need two fingers to zoom the map. But in iOS 11, the familiar pinch-to-zoom gesture is joined by a new tap-to-zoom, which lets you navigate the entire interface with a single thumb. This means that you can easily check the map while walking, or even — if you are an irresponsible psychopath — while riding a bike.

Your mobile data plan takes a hammering when you travel. All the stuff you usually do while sitting in bed using your home Wi-Fi — like reading Cult of Mac and viewing cute capybara GIFs — will eat through your monthly allowance. And that’s before you get to the extra use of maps and Google to find your way around.

Today on Tech Travel Tips, we’ll look at ways to stop your iPhone and iPad from using up all your data in the first few days of your vacation.

At home, you can pretty much trust your own Wi-Fi network, and you kind of have to trust your cellular provider. But as soon as you fetch up at a hotel, airport, Airbnb rental or coffee shop, you risk everything.

Short of leaving your MacBook or iPhone out on the table while you visit the bathroom at a hacker conference, using public Wi-Fi is just about the worst thing you can do with your devices when you travel. Fortunately, there are ways to protect yourself — and they’re cheap and easy.

Welcome to Tech Travel Tips, a week of travel tips for vacationers. This week we’ll show you how to keep your devices safe while traveling, what apps to download before you go, what settings you should change before leaving the house and — kicking off the week — the best travel gadgets to take with you. Let’s get started!

If you find yourself on a mailing list that you either never signed up for, or just got sick of, then iOS Mail has you covered. The app has a built-in feature that detects emails from mailing lists, and offers to unsubscribe from them right there, without you having to visit the sender’s site and hunt for the unsubscribe option yourself, like some kind of spam-lackey.

If you’re using iOS 10 in an iPhone with 3D Touch, you can press on the timer widget in Control Center and pick from one of the preset timer shortcuts. In iOS 11, on the other hand, you get a full-featured, interactive timer widget that you can adjust, pause, and resume, all without ever launching the actual clock app. Let’s see it in action.

You have a big 27-inch iMac sitting on the desk in the corner of your living room office, and yet you’re over there on the couch watching a movies on your iPhone or iPad. Wouldn’t it be great if you could beam one to the other, like sending video from an iPhone to an Apple TV? The good news is that you totally can, just by installing an app on your Mac. There are several available, but today we’ll use my favorite, Reflector.
