powerOne Scientific and Graphing Pro Calculator Reviews

Not Complete Pro Upgrade!

Wendyannh

I selected the Pro upgrade option within Power One Lite when my previous purchase of it would not restore, and this app is what I got. It in ***NO*** way includes all of the individual packs you can purchase separately as promised, especially the financial ones. It is ONLY a scientific calculator with conversions as well. It includes NONE of the financial calculations expected. It does give access to a wide array of user-generated templates, but I want the ones written by the developer that were promised! In order to get those financial applications, I had to purchase ANOTHER complete Power One app at additional expense, which DOUBLED the expected and promised cost of the upgrade. I have relied on Power One for many years for basic calculations, and would have given the original Lite app 4-5 stars for what it does, but this bait-and-switch and doubled expense issue has eliminated most of them. I will probably still use the apps because I’ve now paid a fortune for them, but I’m left with a really bad taste in my mouth. Very disappointed...

Never thought I would find this

I am a professional engineer working in a specialized industry. There are a number of calculations that I perform on a daily basis, many times per day. My HP48G has been a workhorse for me for 25+ years, and I still use it today. I figured it was time to find something that was programmable with a cleaner interface. I thought it would be nice to have something that I could use on my iPad. I spent a few months trying some other apps that didn’t quite fit my needs. Many of the calculations I perform require a specific format in the results. This app is versatile enough to adapt to just about any need you may have. The programming language is very easy to learn and understand. Highly recommended.

Great app

I have tried many calculator apps and this is the one I like the best.

The best scientific calculator app on the market!

As a mechanical engineer I use this app many times a day at work for everything from simple calcs to conversions to calculating beam deflections under load. This is the only calculator app I heartily recommend!

My Favorite Calculator

I have been using this calculator for over a year. I like that you can store variables and see them listed alongside the calculator mode. When a spreadsheet is to big, this calculator performs miracles.

Fantastic calculator

I love playing with numbers and always have this calculator is worth every penny if not just for the ability to add calculators on to it, one side note does I find that the only problem I have is trying to figure out how to do a logarithmic calculator as it seems to not do what it's supposed to when the equations are put in
