Convenient Tool


Love this little guy, one of my most useful and convenient tools that I have in my tool bag. Makes a huge difference in my work day when I have to multiply or divide multiple measurements at once when I can just reach in my pocket and open this app up and punch in the numbers. Is quick and efficient, not to mention it's nice not having to double check my math, search for a pen/marker or something to write everything out on, or spend the extra time doing it all over if something has to be moved or changed (which is quite often in the construction business).

Replace your Construction Master


I am a architecture student but have been in the construction industry for twenty+ years. I have always used the construction master brand. Since being in school I have downloaded the scientific calculator and simply loved it, now with this new calculator it is the same UI for entering key commands and the look is the same as what your used to. I will definitely recommend this to all my construction friends and my fellow students!



I'm calling out this developer, xNeat, for his shady shenanigans! First and largest of these is the ratings he's gotten not only for this "construction calculator," but pretty much all of his "calculators."
Out of the 58 written reviews, (All of which is mostly 5 star with only 6 4 star,) 29 of those were written on Apr. 9th, 18 on the 10th, and 10 on the 11. So all his fatastic reviews happen in a 3 day timespan? Shenanigans! It's not only this app either.
Otherwise, it's just a simple everyday calculator that you can get in black or white. Unless you want to pay $15 for the privelege of getting fractions and a rafter calc. No thank you. You decide if this developer is on the up and up.
