The best Construction calculator there is without a doubt

Construction master was one of the first ones out, and it still remains to be in my opinion The best there is

Was nice

CM Pro used to be the premier option. I bought a handheld calculator more than 10 years ago. But recently they moved to a subscription that I think is way over-priced. I also believe it’s behind the times for these reasons: 1. You can only see one number at a time, you cannot easily see what you’ve previously entered. 2. The History Tape is very hard to use, so unintuitive. 3. Cannot calculate things as simple as parentheses. 4. Saving numbers using M+ and Memory Registers is such an old-school way to do things. Phones are so much better than that. 5. With this, I decided to make my own app that’s meant to be much more intuitive. Please try my app, SteelSolve, free version is completely functional with no ads!

Works great

subscription based trash

I hate downloading apps just to be met with a pay window to use anything. I would rather pay once than monthly for a calculator…
