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 !
Lots of ads, don’t recommend
Lots of ads, don’t recommend
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.
Naja
1) Der Taschenrechner ist ganz gut. 2) Seit Jahren kein Update 3) Werbung ist extrem aufdringlich (kompletter Bildschirm)
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.
Great app
Lots of features, easy to see and understand if you are still a math novice 25 years after high ;]
Watch out!
Popped out a fake system popup about storage being full and needing to install some app to fix that.
Great calculator app.
Has all I need and more for my everyday and project calculations. Pop up ads prevent 5 star rating.
有一些bug需要改进
原来的iPad一直用得不错 换了台Air2就发现很多问题 广告问题不说了 在函数图像显示上黑屏死机状态 无语
Problem
I have to keep restoring purchases every time I use the app. Other than that it is a five-star app.
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.
app freezes and doesnt load
after 4 tries to load app, it still doesnt run, add says will run on ios 6* I have 10* cant say latest updates have helped, i always liked this app, used it for years....now im locked out
Nice multi function calculator and unit converter.
Needed a unit converter for some hobby work and this fits the need plus giving multiple calculators. I could do without the ads, but won't pay for an "upgrade", so this is it!
扣费不符
完整版不是68元吗？为毛却扣80元呀？
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.
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.
Won’t open
Absolutely will not open on my iPad Pro running iOS 14.3.
Love the app - but .......
Wish it had month and year on there too - please add this ASAP Thanks
Bad
It is bad because when you press plus it erases the number that you wrote.
Not bad
Graphics could be less busy, and the extras does make it pricey in comparison to other apps.
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.
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.
GREAT APP!!! All your calculating needs
All your calculating needs in one place.
Complex number????
Ma quale calcolatrice scientifica non fa i calcoli con i numeri complessi????
Wow!!!!
I have the paid version and love it!!!! I have no need to carry a calculator because this app on my IPad is ready for what ever type of mathematical operations I may need..... Would like not to have purchased twice because I have Apple and PC
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.
Excellent Calculator
I have been a calculator junkie since the days of the slide rule. Yes, I am that old. Not that I do much with it, beyond the basics, but I really look for a smooth, fluid interface, with lots of options. Calc Pro HD does everything I need and way more. The pop-up ads are annoying, so when the price drops to a reasonable range, I will pay.
Sig
Poco chiaro il valore temporale del denaro
黄艺博
很一般
One of the best in this category
I have been using this on my new 2020 iPad Pro and have found easy of use and clear data returns clear and well thought out. I will probably pay for the ad-free version. Also, any perhaps even more important - No Subscription!
Thieves
Why do I have to purchase this again after I have already purchase and only change my iPad you bunch of Thieves
Good app
Easy to use, and it's always right at my fingertips when ever I need it
Expensive if you have already bought for the iPhone
The calculator is good, but having bought the full version for the iPhone, makes this a very expensive calculator to add to the iPad. The iPhone version works on the iPad, but the graphic quality is rather poor. So much for buying an app and being able to use on your iOS devices without having to pay again!
Good calculator
Easy to use, but should have more free functions.
Suggestion
I liked the regular version (not pro) When I got there version I felt deceived. I was expecting just the adds out. Now, I can't use in landscape mode on my iPad where I use it. Would you guys keep the same idea on pro? Everything else is perfect.
Poor customer service
This was my go to calculator for everything. However updated my iPad and they don’t link your in store purchases so you have to pay a second time to get rid of the advertisements which are most annoying. Tried emailing customer service multiple times but they never respond.
Great Calculator
One of my goto calculators for iOS.
Migliorabile
Da aumentare le unità nel convertitore! Ad esempio è inammissibile che un'app da quasi 9 euro abbia soltanto grammi e chili nella conversione di unità di peso/massa. E i milligrammi? Questo a titolo di esempio, perchè lo stesso vale per la maggior parte delle unità di misura. Ogni tanto va in crash! Miglioratela e arricchitela! Grazie.
Caicos pro
It very convenient and very helpful, but it does not have the square root.
Excelente Calculadora
Es la mejor calculadora para mi iPad!
Full screen ads
They use full screen ads for an app that is not ever the full version. I think that developers that use full screen ads vrs banners do not deserve my money. It makes them look desperate and greedy. So no, I do not want to purchase your app. I’ll give my money to some one else.
App
Excellent app.
Großer Funtionsumfang, kleine Wirkung
Der Funktionsumfang ist groß, aber leider nicht immer gut. Stürzt öfter ab.
Great app
Great app.
The best single app on my iPad
The Swiss Army knife of calculators. Inverse hyperbolic functions. Cooking unit conversions. Real-time currency exchange rates. Decimal/hexadecimal conversion. Mortgage amortization. Planck’s constant. Linear regression. Phases of the moon. Reverse Polish entry. Cleanly designed, versatile, intuitive, reliable. These people are professionals.
Multitasking!!
Would be awesome with multitasking
Great app
Everything I need and use it all the time
Warum sind die Sonderfunktionen so teuer??!!😡😡😡
Ihr seid soooooooo böse!!
Ganz OK
In der Grundversion ok, die Zusatzmodule sind mir zu teuer. Von der Stabilität her, keine Probleme.
