Home Improvement Calcs Positive Reviews
Best app for estimating costThis is the best app I have found for do it yourself projects it helps you calculate the materials you’ll need and even some cost it helps you figure out sizes and materials needed for the projects it comes in handy especially when you’re at the hardware store looking for the materials you need to tell you how much you’ll need of that material and how much material you might be needing.Version: 3.1.0
Very niceGreat app for newbie contractors or ones who’ve been out of it for a while. In estimating installing flooring could you include installing floating laminate floors including using water-proofing with adhesive sealing in addition to under lament types. Thank you..Version: 3.1.0
The more I use it... the better I like it!I really like this app. The only reason I awarded 4 stars was because, and this may be due to my ignorance, I would like to be able to save frequently used calculations / conversions to a "short list" rather than having to use the menu..Version: 3.1.3
Great!Very easy and flexible!.Version: 3.1.0
Great appGreat app for the home owner or DIY.Version: 3.1.0
So many useful toolsMust have app if you own a home (or are a contractor). If you do your own projects or want to estimate before you hire a contractor. I love the graphics that help you see what to measure. Best measurement/project calculator in my opinion... especially for the price! The 3 add-ons are only .99 each and almost double the amount of tools. Best $5 total I've spent in the App Store..Version: 3.0
I finally found a "home run!"This app is great, VERY useful and has ALL of the formula's that seem to slip your mind with age. I love this... there are sooooo many DISAPPOINTING apps out there and I seem to find them. NOT THE CASE WITH THIS ONE THOUGH!!! Great job guys!!! Now for all the "petty" complainers out there..."yes" I found the ONE spelling error! Still a FIVE STAR APP!.Version: 2.41
Extensive number of calculatorsI'm really surprised at the number of calculators on this application. From building to landscaping and gardening. I added the project calculator and cost calculator and at first glance they aren't as intuitive as the other features but to be fair I haven't given them too much of a look yet. I would recommend this for a Do it yourselfer such as myself..Version: 2.61
Not for interior estimatesAs an app I think this one is probably excellent, per many other reviews. However if you're looking for something like, say hardwood floor or interior estimates, these materials are not included in this app but appear to be items you can buy as an add on. This app is more for professional / serious builders, not consumers..Version: 2.41
Great reference tool for the diy'erMistakes are costly. They take up time and money. Whether you want to learn something new or confirm what you think you thought you kinda remembered. This One will pay for itself..Version: 3.0
Worth it!This app has it all! It has been a real help for me in the field. I'm very impressed with how easy it is to use... The pictures are very helpful for me. Best couple of dollars I've spent in a long time..Version: 2.3
Senior expert home handymanGreat app! Navigates differently, so read the instructions when they pop-up. Great calculators - just about everything you can imagine..Version: 2.2
Good but go for the Home Builder Pro VersionGood but go for the Home Builder Pro Version by the same company, it has the same information but twice as much; don't make the mistake that I made and buy both. It's a great app with lots of useful information..Version: 2.0
Really, really goodI really like the variety of features on this calculator. Many are really handy and really useful. Some I will never use, simply because I don't need them. But hey, for $1.99 how can anyone complain?.Version: 2.0
GreatI love this ap. it has everything. I'm building a shed and it has helped me a ton. Mostly with calculations and the roof pitch/slope. It tells you what angles to cut your wood. Great work on this ap..Version: 2.1

Clever!What a great app! The calculators are categorized so they are easy to find and use, limiting human error. Handy to have!.Version: 1.0
GrumpyNice app.Version: 2.3
Helpful app but missing a key function?Unless I just can’t locate it within the app, you may want to consider adding a sensor function for measuring lengths. Granted, iPhones have this capability built-in (not sure about android devices), but that requires switching back and forth between your app and the iPhone measurement function, which is a nuisance considering that this: A) is a “paid app,” and B) is a *basic function* that one would expect to see in an app of this type..Version: 3.1.3
Just what is was looking for!Starting several projects around the house and was looking for an app that I could use for adding and subtracting fractions for wall framing. As a 1.0 app it's a great start. Would like to see it polished up a little more. The top menu buttons are sunk in for some reason. Also the tile calc I did in inches however it emails out in feet but the math might still be right. Keep updating to get 5 stars!.Version: 1.0
Awesome App!!No need to break out calculators and high school math textbooks to figure out rafter length, brick count, tile count, etc. Seriously, this is a very helpful app and I saved both time and money by getting an adequate amount of materials the first time. Also, I can see how things should look as well as what & where to measure to make sure your project meets code and looks great. This app even lets you price materials needed for your project! Hey developers! Great job developing this app!!!! -Derrick.Version: 2.2

Amazing!If you are a D-I-Yer, a project manager, an estimator or a general contractor this app is for you. I can do it all, if I had to. I can do landscaping, roofing, construction, flooring and painting/wallpapering. I can do all sorts of tough angular stuff,\ and project management calculations. If there is anything I missed, let me know, because I probably forgot to list it - it's in there!.Version: 2.61
Excellent AppFantastic tool for both the iPhone or iPad. A must for the DYI person! I've used this app for over a year now, as a home DYI guy who likes to do it all, this is my only "Go To App" for all the household jobs as well as the woodworking shop. AWESOME is the best word to describe it! No go buy it!.Version: 2.50
