Construction Calculator Plus

...I agree with the prediction complaint. It's a little irritating. While I don't use this for much more than household projects (I'm not a carpenter, or work in construction), it works just fine. The display of a tape measure in the answer is fabulous. My eyesight is not the best, and it really helps. Thanks!

I’m not in the construction industry, but I am building a new house and needed to make some quick calculations from the survey. While not the prettiest or most intuitive UI (you can’t tell I want inches after I’ve just pressed feet and am typing more digits?), it did everything I asked of it. One star off for the lack of prediction once units have been established (who would write something as 6’9cm?) If I type 6’9 before hitting an operator (+/-/x etc) the app should know that’s 6’9”, I shouldn’t have to tell you it’s 9”. Another star off for forcing me in to portrait mode... on an iPad that’s a major pita. Beyond those gripes, as I’ve said, it did what I asked of it without throwing ads at me. For my low volume calculations it’s great, but if you need an app like this for daily use, I’m not sure this would be best (but try it out, I’ve no idea what the competition is like and this may be great relative to them).

Easy to use interface with a horrible twist...you must upgrade to the ‘Pro’ version for addition. ADDITION! Subtraction, multiplication and division keys operate normally however the addition key has a superscript lock over it. When pressed, a pop up screen appears to inform you that addition can be activated by upgrading to the Pro version. Who develops an app that requires an upgrade to perform the app’s MOST BASIC function?! Given the number of positive reviews, this must be a new strategy by the developer as I can’t see anyone giving the thumbs up to a calculator app that doesn’t add. Ahhh well. Back to the App Store to find a different calculator!

When I tried to use the calculator I was met with an unexpected complication. The calculator would not allow me to input a function. I could put in numbers but nothing more without being redirected to the app store for the purpose of another app download. In fact, (with the exception of the numbers) anything I touched redirected me to the app-store to download a separate app. It was a waste of time and frustrating; however, I can attest that the graphic design was pleasant to look at.

You expect to pay for advanced features on a free app, but this on locks the addition button. The most basic function you may want and you have to pay for that option. So basically useless unless you want to buy it. Just make it a paid app.
