The calculator I don't understand why is it so difficult to make a good calculator app. I have tried quite many and there is only one I have found good - RealCalc. After using it for a few years I have paid for the full version.
Needs imaginary number Either i or j, but one is needed. I would prefer j. Could also use other log bases. Other than that, a pretty solid calculator.
Free works fine, glad to pay The free app was so good, I felt like paying for it. Keep up the good work! Sure beats hauling my HP 48g everywhere..
The best softwate calculator available. This is the best calculator I have ever used (and I started with a slide rule). I've used Hewlett Packard and/or RPN calculators all my working life. This has replaced them all. I use it every day on my tablet and phone. If I need to do any thing more complex I use a spreadsheet or Matlab. I only wish there was a version that ran on windows.
I am a fan of the old HP RPN calculators. I tried a number of different calculator apps before deciding on this one. RealCalc has all the features I actually need and use. It's very well designed and written. Simple, effective, logical, and highly usable. Recommended!
Works great Been using the free version for the longest time. Getting the paid version through the promotion was a no brainer.
* Homescreen widget now supports RPN (follows app by default, can be changed in settings).
* New delta-percent function.
* Support for Android 6.0 Marshmallow.
* Fixed possible crash on a few devices running 5.1 (Jiayu S3, Lenovo K3 Note).
Simple calculator with complete history (virtual tape, a.k.a. ticker tape style)
