This calculator helps me with my customers because it allows me to add up their inventory choices at one time and it actually saves it to a spreadsheet so in the future I can remember what they ordered and what they paid. There is nothing more frustrating than to only be able to add up one item at a time. If you need multiple calculators at one time this is the perfect app for you. Great invention and much needed. 👏

The value of this calculator is in its easy way to build functions and variables. Perfect for calculating cost estimations and tweaking the variables to see how the outcome changes. Way more useful than the standard calculator for this type of work.

I've tried all the calculators out there and this one is unique. You have to try it to grasp how useful quick entry and approximate results can be. Plus I love the value adjusting dials.

Very intuitive app that works great as calculator for conversation. It only takes a little time to understand the physics and inputs. Highly Recommended.

If you do any sort of quick estimation, business calculation or are just a numbers person - this is the application for you. It’s worth every penny.

I love the approach this app took with spreadsheets. Allows you to do so much more with your phone that I'd typically do on a desktop!
