Great, esp if you like RPN This is a really nice Android scientific calculator. If you liked the HP-15c, you'll love this, which allows 4 levels of stack visible at once. Suggestion: touch-drag keys to get alt function, this is faster than long-press, and long-press could open other funcs , eg sin,asin,sinh,asinh, sec,asec,sinc all on one key with no 'hyp' or 'shift' needed. Also, would love to see a 'complex' mode (an HP15c feature) as part of the upgrade.
The best scintific calculator as app ever. I have tried a lot of math calculators and none of them are this light weight working pefectly on any phone and with a cool realistic fesign and pefectly acurate calculations. I have used this app for 4 years now and both the old and the new vesion is great. Fast relaiable and good. GREAT JOB GUYS your app should be higher listed in the math app lists.
Extremely responsive functionality shifting rapidly between binary, octal, and hex calculations. An extremely short learning curve to figure out how to activate these important functions( Settings( 3 dotted button above the Shift key & tick the box entitled " Radix Modes " to enable these functions ). Nonetheless, OUTSTANDING APP!!! Great work!!! Well deserved 5-Star rating. I appreciate the app a bundle.
There are so many better ones I'm doing an strophysics degree so having a good calculator on my phone is pretty important. This is not it. You are unable to see the formula you're typing in which makes it IMPOSSIBLE to find a mistake. Also the sin function is no longer accurate at 0.001 rad (pathetic) I'm actually surprised that finding the square root of a number and then squaring it back gives the correct answer. If you need a scientific calc, get something esle. If you want a simple calculator, there are still better options.
Exactly what you'd expect This calculator does exactly what it's supposed to do. It resembles a real (Texas Instruments) calculator as closely as it possibly could. I love how clean and organize the interface is - just like a real calculator's look and feel. No nonsense, no ads, but all the functionality that can be expected from a calculator. I love it!
Pretty great! So the fact that you can't see your full equation is a little annoying, but no big deal, but this app has no extra permissions (as any simple calculator should) and therefore, no usless caller ID! You might ask yourself, why would a calculator have caller ID??? Tbh im just as confused as you are, but you'd be surprised to find that that exists. It's dumb I know. But this app isn't like that! It's actually good! You need a free calculator app? Get this one. Trust me.
* Homescreen widget now supports RPN (RealCalc Plus only).
* 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).
Excellent scientific calculator with expressions, fractions, repeating decimals.
Simple calculator with complete history (virtual tape, a.k.a. ticker tape style)
