Home Improvement Apps for iPhone, Android, and BlackBerry: Your Digital Toolbox

Match that paint color

If you see a color at a friend’s house that would look great in your home, use Benjamin Moore’s Ben Color Capture or Sherwin-Williams’ ColorSnap, free mobile apps for iPhone, to conjure up a matching paint color and code in a jiffy. Take a photo with your phone, and the app matches the paint as closely as possible, and will display secondary and complementary colors. (ColorSnap is also available for BlackBerry.)

Get rid of stains

Good Housekeeping magazine has placed all their best stain-removal and cleaning advice into their free @Home app. It also includes decorating ideas and a searchable list of the 5,000-plus products that have earned a Good Housekeeping seal.

Look for recycled stuff

If you’re searching for a cheap replacement part, or looking for a deal on slightly-used appliances and materials, eBay’s free Mobile app lets you search the auction site’s entire marketplace from iPhone, Android, Windows Phone 7, and BlackBerry devices. You can also put any of your disused-but-functional household items up for sale and recoup some cash.

For listings close to home, search the popular Craigslist site through the free Craigsnotifica for Android or Craigspro for iPhone.

Price comparison

Finding lower prices on electronics and appliances used to mean driving from store to store or scanning Sunday circulars. With the free Price Check by Amazon, you can scan a product’s barcode at a store and compare the price against Amazon and other merchants. (Android and BlackBerry versions are also available.) PriceGrabber has a similar app for iPhone and Android.

Carpenter’s tools in one

For $1.99, the iHandy Carpenter app puts a ruler, protractor, bubble level, surface level, and plumb bob into your iPhone, allowing you to make measurements without lugging out the tool box. It’s perfect for simple jobs like hanging frames and mirrors.

Need just a level? There’s a free app for iPhone from iHandy and for Android from Johnson.

Light the way

With the iPhone’s bright display and the super-bright LED flash, you can use it in place of a traditional flashlight to illuminate crawl spaces, attics, cabinet recesses, and other dark spots. There are many apps for this purpose, but two favorites are the 99-cent Flashlight (and 99-cent Flashlight+.

Find a stud

Using your iPhone’s magnetometer, StudFinderPRO can help you locate studs by locating the magnetic fields emitted by metal objects like screws and nails. The app costs $2.99. A free Magnetic Stud Finder is available for Android devices.
