Better than the actual calculator

I have been using this calculator for years as a concrete business owner. After breaking and losing so many of these I finally just downloaded the app and boy was I pleased. It's crisper easier to use and honestly going to save me money and heartache when I can't find my Calc. Ty for this

Very satisfied customer

Handy on the Jobsite

Useful tool to have when walking the job site. Much easier than having to carry a full size calculator. I think $25 is a little more than it should cost personally, but it’s still cheaper than the real calculator. One complaint I have is the App icon looks very dated aside the rest of the apps on my phone. Hopefully that isn’t a sign that it no longer receives updates, or that it will become incompatible with new iOS versions.

Exactly what I wanted

As a carpenter I have used a construction master from foundations to roofs, and everything in between. When I wasn’t wearing my tool pouches I was always running back to the truck to get my calculator. Now it’s always by my side.
