Calc Pro Reviews

I needed a different financial calculator with the n iy pv pmt fv buttons

I bought this to avoid the ads on the free version and now the rpn Calc is not working in rpn mode. There is no Enter button. Ugh!

The loan calculator part does not work correctly. When trying to determine interest amounts the calculation does not show the results

I originally purchased CalcPro for the iPad and was very pleased with it. When this new version came out I had to pay a significant amount to get it on my iPhone 6. Also they left out some of useful features that were on the original iPad app. On the iPad app using the graphing calculator you could find the coordinates of any point or a tangent to the curve at any point. The new app left out these features. Also, the new app does not support landscape mode for the iPad or the iPhone. Landscape mode is my position of choice for the iPad. Another thing I noticed is that the data given for the maximum/minimum of at lease some of the graphs are not correct. This is especially noticed for the "y" coordinates. Looking forward for a new update.

I've used CalcPro for nearly a year. It rarely disappoints. I use the RPN mode, which works well. The range of calculators is great. I use the scientific, programmer, loan, units, and date/time calculators with some regularity. You can't add/subtract months or years, Calc in the loan calculator doesn't cause typing in the last entry field to overwrite, entering 1.05 only shows 1 until you hit 5, and normal calculations misbehave in the financial calculator, for example, so CalcPro has its problems. However, it is handy, useful, and powerful.

This calculator is full-featured and extremely useful. I like that it supports RPN, base conversion, trig, unit conversions and stack manipulation.

Apart from a few minor user interface issues, the only thing that really must be addressed is CalcPro 's slow load time. Looking at a splash screen for 3-4 seconds when you want to do a quick calculation is a little frustrating at times. Let's hope this can be improved.

All-in-all a great product and definitely a steal at $0.99.

I have enjoyed CalcPro for years, until last week when I couldn’t get the date to reflect the current date. Today I went to CalcPro Store and decided perhaps I needed to purchase a new version of CalcPro .$7.99 vs what I believe was previously Free!
Only to receive the exact same notice , “unable to connect” ... while I am connected to the Internet! Wi-Fi on my Apple XR.
Now I’d like my Apple charge refunded !
Ever hopeful someone will contact me!
precious Auntie

Since updating to the latest version of iOS CalcPro no longer works.

They refunded my money after I paid and they failed to remove ads. I rebought it and the ads are gone...

Love it...

6s. It opens and then closes. Useless!

I use finance, scientific, and base conversion the most and occasionally the plotter. Everything in one app!

Been using CalcPro since the ice age and can’t live without it. Best I have used!

Solid App for the smaller (3.5 puny inches!) iPhone screen. Separate screens for different calculator tasks enhances functionality and user friendliness. Not Universal nor is there a dedicated iPad version yet. For a full functionality calculator app like this, where there is a lot of visual information and many touch keys packed onto the screen, full use of the larger iPad screen would be a delight.

Love this Calculator. Use it all this time for a variety of projects. Keep improving it maybe add a carpentry calc or other building construction calcs. Thanks GB

The functionality is very good with lots of bonus features. I haven't full explored yet but have thus far used the Finance, graphing and scientific modes. One stand out feature that swayed me toward this calc is the integrated unit converter. I use it a lot at work.

Great job developing this very useful tool! It was worth the $8!

I have used Calc Pro for several years.
Working with international companies, it converts units of measure and currencies in any direction.
Extremely easy to use interface allows me to do the calculations and conversions without having to remember key sequences or functions.

After using regression in Statistics and push reset. Then, if you push regression button, a whole calc pro disappeared. Only solution was to delete the Calc Pro and reinstall it again. I did 3 times already. This is a major bug. This statistics program is
not good. Can not do simple statistics calculation such as finding n, x-bar, sigma, .... By inputting x=vale, enter consecutively.

Hope you correct this and at least add group input ,

x=value x n, enter .
Example:
Value n
2 x 3 Enter
4 x. 5. Enter
5 x. 4 Enter

Find. n, sigma, x-bar,

Excellent multifunction calculator with just about all of the major math needs. Only missing calculator functions are specific needs such as upper level mathematics, electrical, physics and any available specific math equations programmable on the specific scientific models.

Bought this so I could stop using the one built into my iPhone 3GS. Would like to see at least 1 additional number after the decimal in the tax rate e.g. My local tax rate is 8.625% but I have to set it to 8.63% causing errors to be made in the tax calculation.
