Fortunately, a multitude of smartphone and iPad apps help make designing and decorating our homes much easier and far more exciting than ever before. From basic room makeovers that just involve redoing the furniture layout to renovating your kitchen to building a home from the ground up, there’s an app that aids the process. The offerings include apps that serve to inspire with endless photo galleries replete with furniture resources; other applications supply detailed how-to guides for every home improvement project imaginable.
There’s an app that serves as a picture-hanging level, another that will provide the measurements of a piece of furniture, and one that offers a 3D-photo-realistic view of a floor plan — a tool upon which some architecture and interior design professionals rely.
These apps are some of our favorites out there:

Houzz is the largest database of home design ideas on the Internet. The app is similar to the site in that it features an extensive catalog of photos listed by room. It’s possible to narrow your search with subcategories based on style and location and to type in specific requests such as “moldings,” “counter materials,” and “bath fittings” to refine your hunt further. You can bookmark designs in your own idea book. The app also has lists of products for sale and professionals who can help you realize your design. Have children? Try the app Houzz Kids’ Rooms.

This clever app allows you to photograph color inspirations that catch your eye and instantly find their match among Benjamin Moore’s 3,500-plus paint colors.

Online real estate database Zillow launched Zillow Digs as a hub for home remodeling ideas and to give users an understanding of how much specific projects cost. Users can browse and save images relating to rooms, styles, and specific elements. What truly sets this app apart? It provides users with remodel estimates on the kitchens and baths that inspire them. Estimates are based on location and are broken down by materials and labor costs. The app helps you find professionals to do the work, and you can follow, and comment on, other users’ projects.

In what looks like a hybrid of Instagram and Pinterest, RoomReveal makes it possible to show the progression of your home improvement project. Users simply upload photos and provide a narrative. Not only does the app serve as a personal scrapbook, you can track — and, again, offer your comments on — projects other weekend warriors and design professionals are tackling. The catalog of projects changes daily. Users can also search by room, follow their favorite DIY homeowners, and seek out designers and architects.

This app is an amazing all-in-one pocket-sized tool kit essential for anyone undertaking a home improvement project. Once you have it, you’ll wonder how you ever lived without it. It features five commonly used carpentry tools: a plumb bob, a surface level, a bubble level bar, a ruler (swipe left and right to measure things longer than your phone), and a protractor that measures angles from 0 to 180 degrees.

While it’s tough to imagine that a handheld device can serve as a sophisticated starting point for building a house from the ground up, this one does exactly that. Starting in two-dimensional construction mode, users pick a floor plan, draw rooms, and adjust the height or thickness of walls. It’s possible to drop in furnishings and lighting from a database of hundreds of objects and to select door and window styles, floor coverings, and wallpapers. When the design is done, a click of a button can turn it into a 3-D version. Users can experiment with all sorts of redesigns and then take a tour of the new look with a 3D walk-through. The basic app is free, but if you want to save your work and take advantage of more features like an additional furniture pack, you will need to purchase upgrades, which start at $4.99.
Cost: Free (basic version, shown here)

If you’ve ever found yourself without a tape measure, EasyMeasure could be your answer. The app shows the distance between objects as seen through your phone’s camera lens. When you boot the app, calibrate it; enter your height minus four inches to get to eye level. Utilizing a 3D-camera-overlay grid, the app makes it possible to calculate the distance between furniture in your living room. Just stand at one piece and aim the camera at the base of the other. Want to get the width and height of an object? The upgrade will cost you a buck or two.
Cost: Free (measures distance only in basic version)

Renovation projects of all scopes will benefit from this photo-centric app. Pictures and design boards (collages of photos) are categorized according to space and style. It’s possible to organize ideas by picking your favorite photos and then cropping, resizing, and rearranging them to create personalized design boards that can include notes and drawings. For example, a design board for kitchen ideas would include “pins” of kitchen remodels you like. It’s a good way to visualize what colors and elements blend well together. One feature offers a directory of prescreened local professionals rated and reviewed by homeowners.
