Whether you're painting a wall or building a piece of furniture, it always helps to have an assistant. But an assistant who fits in your pocket and can go anywhere? Now that's a DIYer's dream.

With that desire in mind, we scoured Apple's iTunes App Store for the handiest and most innovative iPhone applications. Below are our eight favorite apps, each under $5. Think of each one as your very own pocket-sized assistant.

Dimensions iphone appiTunes App Store

Dimensions by pocketDEMO ($1.99)
This heavyweight app boasts 13 three-dimensional tools, including a caliper that measures with several hundredths of an inch precision, a ruler, a spirit level for vertical and horizontal surfaces, three different tape measures that "stretch" to lengths of 8, 16, and 82 feet, and an ingenious mechanism that computes distance, volume, and surface area.

ID Wood by Double Dog Studios ($4.99)
Contains full-screen samples and detailed info on nearly 160 different types of lumber, from the basic to the exotic. Get pointers on durability, sustainability, and color variations, as well as advice on proper cutting techniques and nail-size requirements. Botanical names and thickness indicators aid the selection process while a comparison screen shows how a specimen looks both finished and unfinished.

Ben Color Capture iPhone AppiTunes App Store

Ben Color Capture by Benjamin Moore (free)
Having trouble finding that gorgeous aubergine tone you spotted on the walls of your favorite boutique? Just snap photos of shades you love, upload images, and get their closest matches. The company's extensive (3,300-plus!) color library enables you to create and save a virtual paint chip that can be recreated in-store. A "Harmony" toggle creates four complementary colors -- just like finding opposites on an actual color wheel -- while "Strip" creates six similar colors to one you've chosen.

Cal's Plumbing Video Tutorial – Minor Toilet Rebuild by Dennis Nederlof ($0.99)
One in a series of seven plumbing repair step-by-steps by veteran San Diego plumber Cal Campbell. This one, a comprehensive video tutorial featuring Campbell fixing a real-life busted throne. Cal swears his know-how will help you succeed in repairing a toilet yourself-and will save you up to $150 on costs and labor. You'll download a list of necessary supplies and a comprehensive manual to consult along the way. Email support is even offered by Cal himself.

App Tools 16 in 1
Talk about a multitasker! This super app is perfect for a DIY remodel. It packs 16 useful applications, addressing a slew of home improvement needs. Features include a bubble level, ruler, protractor, talking calculator, plumb bob, unit converter, height calculator, and personalized invoicing tool. But what really makes this app standout is its eye-catching graphics: some of the best iPhone eye candy we've seen.

Home Improvement Calculator by PunkStar Studios ($4.99)
This handy app does a whole lot more than your average calculator. It's designed to help you determine how much paint, wallpaper, mulch, tiling, wood deck, gravel, concrete, or fencing you'll need for your project -- and how much it's all going to cost you. The app's tiling segment even allows you to enter the width of grout and offsets that value by number of tiles needed, preventing over-ordering for larger projects: a common DIY blunder.

Flashlight iPhone appFlashlight by ExactMagic. Photo: iTunes App Store

Flashlight by ExactMagic
Maybe you're burning the midnight oil -- or you're simply working in a dark boiler room. This DIY favorite transforms your iPhone into an ultra-bright flashlight. Its intensity makes it useful in even the lowest light, but its versatility is what really makes this app shine. It features a variety of light colors, bulb styles, and brightness levels, all of which can be controlled by tapping the screen. And the different colors aren't just there to look pretty; they actually serve different functions. Red is recommended for night vision; blue is best for early dawn; and yellow is a softer alternative to white light for daytime.

ServiceMagic by IAC Mobile (free)
Need to call in a pro? This app gives you access to the ServiceMagic's roster of home improvement professionals, including contractors, plumbers, electricians, and landscapers. Request quotes, browse thousands of photos of other people's projects, and share your own DIY experiences. Each of the site's 60,000-plus registered members is trade-license and insurance-verified. Pre-screening has ruled out those with criminal or civil judgments placed against them.

    DIY Diary: Renovation Red Flags :
    I have to say that in all fairness, not all contractor that bid low are a potential for bad work. My boyfriend is a carpenter/home improvement and because of the lack of work out there, he has been underbidding so he can get the job. He needs to make a living too. All of his customer are always completely satisfied and has been recommended to friends and family of the customer. Often he has been rehired to perform other jobs they need to be done. He is licensed and takes a lot of pride in his finished product. He has also been contacted by customers who had that top bidder hack up a job or took half the money and never completed the job. He is more than willing to work with that person to help them out in a tuff and unfortunate circumstance. So in all fairness in this hard of times it's really not fair to say low bidders are a red flag. There are good guys out there who have a talent and bid low because there are bills to pay and mouths to feed. Making a 500 dollar profit rather than a 1500 or 2000 over bid profit is better and more honest than taking a customer for granted, and it keeps your head above the water so you can get by in tough hard times. How about those high bidder's paying there under paid illegal's who practically work for peanuts and have absolutely no experience. This is an angle perhaps you should investigate and write about. If I had a flower for all the jobs my boyfriend lost to a contractor like that, I'd have an allergy fit. So please don't put down the little guy and tell people to watch out for those low bidder's, yes there are shady characters and people should definitely always do there homework ask for references and phone numbers, go check out there work. But don't disregard there low bids because there just trying to get by too. Thank you, Monique
