PCalc

Home Screen widget used to be great but it’s been gone for years and hasn’t been updated to keep up with iOS

I purchased the full version and had a question on some usage. Sent an email through help option and got reply within few minutes. Extremely useful for engineers!

If you’ve ever had one of the classic hp calculators, you’re in for a treat. PCalc has an RPN mode that will take you back and remind you how RPN may take some getting used to but is ultimately a much better way to make accurate calculations, regardless of their complexity. And if you don’t like RPN, regular mode works great too!

The old widget doesn't work in the latest version of iOS. Bring back/rewrite the calculator widget!

iOS 18 build-in calculator redesign is a disaster. I don’t know what was Apple thinking. You can’t even do % calculations correctly there. Well, after being super frustrated with the idiocy of Apple devs and their dumb decisions regarding how calculators are supposed to work I found PCalc!!! What an amazing app. After trying the free version for couple of weeks I bought the full version and deleted the Apple’s built in Calculator. This calculator app is THE BEST! PCalc can be added to the Control center, has custom icons if you want to change the default one, and amazing themes/skins. What an amazing calculator! Thank you to the dev team who stand behind this app.

This calculator does it all! Except what happened to the Widget in iPadOS 18? 18.1, still gone!

The latest update removed the widget calculator. It was nice and convenient to have. I’m not sure why it was not able to transfer and work with the latest update.

Please update to allow this app in control center replace in-build calculator

I live this app and loved that I could access it as a widget. That no longer works unfortunately so the app has to be launched to be used. I hope an update brings that functionality back.

Everything below still stands - BUT I need the widget for IOS 18! Seldom have I come across a program of any type which can be called "Excellent', but this is the real deal. Throw out your TI, your HP, your Casio. PCalc magically transforms your phone into a state-of-the-Art customizable calculator. For all your calculating needs, be it simple, scientific, or computer science. Yes, it might be nice to have business/finance functions. But I just love this program for what it does, and at an extremely reasonable one-time cost. You can't go wrong. It even has a really handy widget for the iPad. I love it!
