Calc Pro HD (paid version) is my go to Calculator App.
I use Calc Pro HD (paid version) more than any other app. I use it for calculating numbers, I use it for all kinds of conversions to include currency conversions. I Love this App it’s AWESOME !
Does not work with keyboard
I would like this app a lot more if it worked with the physical keyboard. This is a flaw shared by a lot of the iPad calculator apps, which is a shame considering that the keyboard has been a common accessory for many years now.
Wonderful App, but…
The time and date calculator has a small bug. It correctly calculates the difference between two dates and times, but is off by one when calculating a date/time a certain number of days in the past or future. The calculation is always off by one hour. For instance, if you asked for the date/time 1 hour from Feb 2, 9:00, it will say Feb 2, 11:00. If you ask for the date/time 0 days and 0 hours away, it will say Feb 2 10:00.
Other than that, this is a well done and extremely useful calculator app.

Great app
Lots of features, easy to see and understand if you are still a math novice 25 years after high ;]
Lots of ads, don’t recommend

Use for the Tough Stuff
This is my “go-to” calculator on my iPad. Works great! I’m not a math guru but I can count on the Calc Pro HD app to bail me out when I need expert help. Would get again.
Problem
I have to keep restoring purchases every time I use the app. Other than that it is a five-star app.
Great calculator app.
Has all I need and more for my everyday and project calculations. Pop up ads prevent 5 star rating.
Totally Awesome
This may be the most functionally rich calculator available on the App Store. That coupled with its implementation of Reverse Polish Notation makes it unquestionably FIVE Stars. When you add in all of the other features then I’d really like to give it five times five stars.
Excellent App
I love this Calc! Lots of features and easy to use. I’ve been using it for years and it’s always worked and still works well.
Watch out!
Popped out a fake system popup about storage being full and needing to install some app to fix that.

EXCELLENT
This calculator is amazing best I ever used
Very useful
Well designed and easy to use. Very powerful functions that you can use for any calculations and functions.
No Support
No updates in 3 years and currency converter no longer updates (my last currency update was more than a year ago. My guess is Panoramic Software Inc. no longer exists. Email I sent thru the app rejected as nonexistent.
Won’t open
Absolutely will not open on my iPad Pro running iOS 14.3.
Great at first, now it doesn’t work.
I purchased this app a couple of years ago and thought it was so awesome! The different calculators, the ease-of-use, the customizability of the calculators was fantastic! Now for some reason when I go into the app it automatically closes. I go into the app again, and again, and it just closes. It will not allow me to use the app at all. Originally the rating would have been five stars, but now as I cannot use the app I am regretful to have to rate it a one star. I hope somehow my issue can be resolved. I really love this app and would love to continue to use it.

All in one app
easy to use, nice design. A must-app that is great.
Paid version doesn’t work anymore
I’ve been using this calculator for years. I even paid for it, the paid version won’t even open anymore and I had to redownload the free one. I couldn’t even get the link for app support to work. It hasn’t been updated in years.
