When QR Codes (short for "Quick Response" because they can quickly be read by a mobile device) started showing up all over the place, I didn't really understand what they were and why I should use them. I've since learned that they're similar to a bar code except they can store far more data, such as website addresses, business card information, coupons, and app downloads.

Years ago, I downloaded one of the many free QR reader apps. But, whenever I'd be flipping through a magazine or walking by a sign that displayed one of these things, I could never remember which of the (literally) hundreds of apps on my phone could read it much less what the square thingies were called. All of that has changed with iOS11. All you have to do is aim your camera at the code and BAM .... the camera reads it and takes you to wherever the QR code is pointing. It's that simple! And, Android users have the same camera functionality using Google Lens (but only with certain phones).

If you haven't already done so, I urge you to test it out! You may find that it's far handier than you ever thought.

Have any of you experienced any surprises when scanning QR codes? Where's the weirdest place that you've ever seen one? Share your stories in the comments below.

When I find an app that works, I tend to stick with it until it starts pissing me off. The Apple Podcast app worked perfectly until iOS11 when its basic functionality and ease of use was ruined. The interface has become so distorted that it's impossible to even listen to podcasts in sequential order without having to muss and fuss with it. I tolerated this for months until I finally gave up and started the hunt for something new. And, at last, I have found it! The app is called Overcast. It's simple to use and delivers exactly what you need plus a couple of extras.

• Limit the number of podcasts that are saved in your queue. I often become overwhelmed when I have too many podcasts stacking up. The app has a setting that allows you to assign the maximum number of podcasts that it will save for a specific show.
• Organize podcasts into lists. I didn't think that I would like this feature. But, since playing around with it, I've found that I enjoy being able to hit my NPR list and let it roll.
• Fast forward through silences or dead spots and then return to normal speed once the silence ends.

If you've been looking for something to replace the Apple Podcast app, Overcast is for you! Leave a comment below and let me know if you're ready to make the switch. Or if you've already found something new, I'd love to hear about that, too.
