The best architectural calculator I found

I have been using this app for years and it is by far the best I was able to find. None of the others have mastered the input of feet and inches. The calculations are smooth and the units convert so easily. Please, please continue making this available. I am happy to pay even again if you can add a tape like function and maybe make the vertical one with easier conversion settings now that our screens are often bigger.

This is my daily architectural calculator I never want to miss.

Great converter

I like this calculator. It is a great calculator to use as a converter between metric and imperial. Very practical and easy to use.

Crashes IOS 14.2

Developer please update app.

Not worth the money

Paid $6.99 expecting this to be better than the other free apps. This was a waste of my money as a find the free apps work just as well and better.

Great but missing a few simple things

Been using the free version for years but need to do calc for run, rise, diag. The app handles it easily but you can’t store the results or do further math with the results. For example. Calc the diag of 4x4s 8’ apart. Easy but now subtract the diag of the 4x4s to get the inside measurements. Can’t do that. Can’t even save either diag measurements. Need a good memory or paper and pen. Hopefully a future enhancement. Love the app anyway.
