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.
Good but I wish I had noticed that it obfuscates formulas when typing instead of showing you the process on screen. E.g 2+4+5+6 showing as separated instances of 2, 4, 5, 6. If you don't need this functionality however I wouldn't worry.
When it's the best, it's the best. This app has been the best spent money in all the play store. It's fast, accurate, stable, configurable and it is really the perfect calculator. And I can say the same for both algebraic and RPN mode. A must have if you need a scientific calculator! And unlike other apps, it's becoming better and better in a steady and sure way. Can I give 6 stars?
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.
BEST Calculator, love RPN Nestler was my first slide rule-kind of 1965 abakus, then hp25, 41(the best),50g (worst,not same rpn). Then came RealCalc! Survived all my phones, zte(?), galaxy s2 s3 s6 a5, Sony Z3 (fell apart after 9 months due ìnternal heat,no repair available.) Great RPN! !!!
Careful!!! It gives Wrong results While working with triangles calculations, cos, sin and tan I got wrong results, compared to a calculator machine and tested on CNC milling machine, buy the way I've bought the full version cause I needed at my work but what can you do with a calculator that can't calculate.. Contact me if you care for more details to fix the problem
