The difference between an app and more traditional software is that apps are designed as specialized programs meant to do one thing quickly and easily, with the emphasis on easily. I was reminded of that this morning when Eddie gave me an article to read in the Wall Street Journal. At the bottom of the article was a QR (abbreviation for quick response) barcode with the caption "scan this code to watch a video…" Being curious I gave it a try. As soon as I scanned the code with ScanLife, one of the many scanning apps available for my iPhone, the whole process got me thinking about some of the simple, everyday smartphone apps that I use to simplify my life.
- QR Codes are a form of barcode designed to provide easy access to information through smartphones. QR codes appear everywhere these days: in newspapers, magazines, and on the grocery shelf. Use your phone to capture the code and you might open a video, read an expanded article, or find out more about a product. If you are out shopping, there are apps that will scan product barcodes for comparison shopping.
- A slightly more complicated, but very useful app is Scanner Pro by Readdle. The app scans documents with the iPhone or iPad camera, and does an excellent job of making readable, reproducible copies that can be sent to a printer or saved as a jpeg or PDF file. Scanner Pro is a paid app, but the publisher just released a free version of the app, Scanner Mini. The Readdle apps are only available for Apple, but you can find out about similar Android apps here.
- Another class of apps I regularly use are timer apps. As I write this column I am sitting on the veranda outside the Paul Ruth Room waiting for my laundry in the washer/dryer machines. To make sure I take my clothes out of the machines on time, I set a timer to let know when to go back inside. I also use timer apps when I cook. Many of the apps let me set multiple timers at once, which is very helpful when timing a variety of dishes on the stovetop and oven. A timer is built into the iPhone Clock app, and there are a multitude of third party apps available for iOS and Android devices.
- Weather apps are a must – everyone always wants to know about the weather. I use the iPhone's built-in weather app and The Weather Channel app for forecasts, but I really like Thermometer, a free app that only does one thing – displays the current outside temperature. It is especially useful when we are traveling and I want to find out the temperature where we are at that very moment. A free app with the same name and function, but from a different publisher, is available for android devices.
- Keeping track of my grocery list was always a chore. How many times did I arrive at the supermarket and forget to take my list, or I'd be out and remember something I needed, then forget to write it down when I arrived home? Since getting a smartphone I keep the list in an app, and my grocery shopping life has been easier. There are numerous grocery list apps, and the one I use is Grocery Gadget. It includes a very extensive database of grocery items, organized by categories, and as you shop you can chose to arrange list items either alphabetically or by category. There are both free and paid, ad-free versions of the app, and they are available for both Apple and Android devices.
- Every smartphone includes an app for takings notes. In the past I kept a little note pad in my purse – and I was always looking around for something to write with. I now use the native Notes app built into my iPhone. When I want to write something down, I open the app, touch the plus sign for a new page, touch the screen for the keyboard, and begin typing.
