  • Extensive number of calculators

    by Northwestflyby

    I'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.

  • Handy app

    by BAMBAM*69

    This app is a very useful tool on the job site.

  • Super Home Improvement App

    by Lesview

    Very Very helpful. It teach you things you might not know.I love the sensor level. Works great.

  • Not for interior estimates

    by House hunting hobbyist

    As 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.

  • I finally found a "home run!"

    by LogicalPop

    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!

  • Great app.

    by Partypooper419

    I was looking for an app to make remodeling easier and I have found the best ever. If you are not sure about a lot of aspects in the remodeling area this is a great app for you. It's shows you instructions on how to do things and it shows you how much money you will need for a particular project. I will be using this app all of the time in my business.

  • Senior expert home handyman

    by Mels-man

    Great app! Navigates differently, so read the instructions when they pop-up. Great calculators - just about everything you can imagine.

  • Awesome App!!

    by -Derrick

    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

  • Great!

  • Complicated and worthless

    by forrest44

    Unless you are Einstein, you will never figure out how to operate this app. Confusing, complicated, and very disappointing

    by CraneGuy165

    I like this little gem of a app. Has the calculator for fractions and computes many measurements for framing and concrete so I can finish the job quicker and less hassle.

  • Great

    by Moestyle2000

    I 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.

  • Lots of help!

    by Brudog351

    Very handy!!!

  • Good but go for the Home Builder Pro Version

    by DR.ankin

    Good 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.

  • Really, really good

    by Dalex1953

    I 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?

  • Need basic fractional calc

    by Hergy_1

    Lots of useful info but really needs a fractional calculator so you can add 1/16, 32nds etc. Also a table comparing nail sizes would be helpful......4 penny, 6 penny etc.

  • Don't waste your $$$$$

    by Tim1324

    Not good .

  • Terrible

    by Petie_G

    Save your $$$$. I bought this for some help on windows and doors. They have info on installing wallpaper, but nothing on windows and doors. Who uses wallpaper these days.....not many!! This app needs a lot of upgrades before they charge $2.99. Give me a break!!!

  • Wow

    by ttt486

    Wow does so much more than all the other apps on here and then some.

  • Just what is was looking for!

    by WJKramer

    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!

  • Clever!

    by Sven from Wisconsin

    What a great app! The calculators are categorized so they are easy to find and use, limiting human error. Handy to have!
