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.
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.
Lots of features, easy to see and understand if you are still a math novice 25 years after high ;]
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.
I have to keep restoring purchases every time I use the app. Other than that it is a five-star app.
Has all I need and more for my everyday and project calculations. Pop up ads prevent 5 star rating.
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.
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.
Popped out a fake system popup about storage being full and needing to install some app to fix that.
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.
