Construction Calculator Plus

It charges for very basic features of calculators. It essentially only lets you display numbers. You can also pay to use a flashlight, already included in your phone.

I can’t believe it we have to upgrade to use the plus button Back to looking for more calculators

I use it everyday

Great calculator. I enjoy using it when I need it for work or at home on small projects

Horrible forces you to pay to use the plus button.

And no apparent way to unlock…. Even for a fee

It’s not updated, crashes, and this developer is a flat out liar with this app. Bait and switch once you download. Recommend going with Tape Measure Calculator Pro - just works as expected

I can’t use the add button not really to pleased by that so I’m glad I multiply more along with dividing.

I went back in and tried again. It says free, after paying but then when you go into the now paid app that’s free it has 🔒 <—- just like this not allowing you to use them. I’m done. I have pics to prove, and a CC showing multiple charge. Plz refund.

I just opened the app and I get rating screen, maybe I can use it first before I rate it?
