Overview

If you think a smartphone is a high-tech toy, you’re only partly right. Aside from being a lot of fun, a smartphone can be a powerful, practical DIY tool. Once you have one, you might find that it’s as essential for DIY as your tape measure or cordless drill. The pros already use them. So should you.

Consult an expert anywhere

Editor Ken Collier has a dumb phone and lives in Minnesota. His son has a smartphone and lives in New York. When his son needed a wrench for his plumbing project, Ken explained what to look for at the store. Pretty soon his son called and told Ken to check his e-mail. He had sent a photo of the wrench right from his smartphone while he was at the store. Ken confirmed he had indeed found the right wrench. You too can use a smartphone to get help. (But don’t call Ken.) The plumbing project was a complete success.

Compare prices instantly

Load a free “bar code” application (app) on your phone. Then open the app and scan the product’s bar code right there in the store. The app instantly checks for the lowest price at other local stores as well as online sellers. If you find a lower price online, don’t forget to factor in shipping costs.

Record strange car sounds

The next time your car or appliances make strange sounds, make a recording with your smartphone and send it to the mechanic or repair technician. They'll be better equipped to give you an accurate diagnosis.

Protect the screen

Every phone store sells screen protectors. But the best ones are made from the same material used to protect car paint. Buy a die-cut protector made specifically for your phone (available from ghost-armor.com http://www.ghost-armor.com/), or buy an 18-in. square of the material (available from clearmask.com http://clearmask.com/) and cut it yourself. The 18-in. square sheet is enough to make screen protectors for the whole family and the neighbors.

Pull up detailed information instantly

You’re starting to see quirky-looking Quick Response (QR) codes (also known as “snap tags”) in magazine ads and on some products. Pretty soon they’ll be on everything. The code is actually a shortcut to a specific Web page. So if you want to learn more about a product, you don’t have to boot up the phone’s browser and then enter a long URL. All you need is a free QR app. Frame the QR code in the camera and the phone does the rest—you don’t even have to press the shutter.

Get the right part

The appliance (auto, plumbing, computer) parts store always seems to ask for the one piece of information you didn’t write down. So shoot a photo of the entire appliance nameplate and take it with you. Sure, you can do that with any camera phone. But can you read the numbers on that tiny 2-in. screen? Nope. A smartphone screen is much larger and lets you zoom in to read smaller information.

All you need is a smartphone and a holster or case.
