Everything I wanted and more but...

I’m in no way in the construction industry, but I am building a new house. Having just received the survey, I wanted to do some calculations on my current square footage, the overall length and width of my existing home etc... nothing major, purely low volume stuff.

The app worked perfectly, doing everything I asked of it and allowing me to do more (the triangle calculator was handy for getting an idea of the size of my new homes roof)... tho (and maybe I missed it), I would have liked to be able to get a slope/pitch ratio from my input of the angle (I actually couldn’t get any of the pitch x/y buttons to work), minor detail as I’m setting my roof by the angle of my latitude for a solar PV array.

One star is lost because I *wanted* to toss the few dollars your way for making just the right app available for me at just the right time. Problem is, every time I click on the “Remove ads” button the app crashes... this is a 6th gen iPad with the latest iOS installed so... no cookies for you. If there’s another way (a pay for, ad-free version on the AppStore say) do let me know as I really appreciate the effort that went into this !!

While we’re at it, it’d be nice if we could change the font color as well as the bg color... I do love a black bg with green text for that old terminal feeling !!

Developer Response

Sorry for taking so long to get back to your review. Please email me at to go over all of these issues.

For the triangle, click on the numbers next to T:. Then click on the Pitch button. Now you can change the numerator and denominator using the top and bottom pads. If you want to input degrees and get a pitch, hit 'Degree', then enter your degrees, then select Pitch.

There are Theme settings under settings, so you can change the background and font color. I don't have a green on black but I can add that in the future.

Please email me ( so we can figure out why the purchase isn't working, or if you have any other questions or feedback.


Best calculator

I work as a carpenter and I can tell you that this is hands down the best calculator when doing layouts and finish/framing work. Easy, fast, and great user interface. A bit pricey if you wanna remove the ads but I’ve used it every day for the past 3 months that I decided to actually buy it and contribute. Thanks for the product.


History tool

The history function allows me to go back and verify that all of my inputs were correct and check my work. For me this is very nice feature as I can make sure a typo does not mess up my project.
