FAQ:

* If you want data size conversions in multiples of 1024, use kibibytes, mebibytes, gibibytes, etc - see en.wikipedia.org/wiki/Kibibyte.

* If the percent key appears to give wrong answers, make sure you are pressing '=' at the end, e.g. '25 + 10 % =' will give 27.5.

* If sin/cos/tan functions don't give the answer you are expecting, make sure you are in the correct angle mode. Degrees, radians and grads are supported, indicated by DEG, RAD, GRAD in the display. Use the DRG key to change mode.

* If any of the digit keys are disabled, or the decimal point doesn't work, or you have answers with letters in, or basic arithmetic appears to be wrong, then you are in binary, octal or hexadecimal mode. Press DEC to return to decimal operation. If you don't need these modes, please make sure that 'Enable Radix Modes' is disabled in the settings.

* If you can't find HEX, BIN or OCT modes, go to the settings and make sure that 'Enable Radix Modes' is checked.

Works for what it does But needs more functions for the price. For instance it doesn't have functions for logs other than base 10 so I can't use it for several things I need. Refunding but will, re-evaluate if things change.

Raymond Wilson

Why mess with the design? I now have a stupid bar along the top with two options that should have been left in the Settings menu. Also, there is now two Settings buttons, one in the top-right and one at the bottom of the screen. They both do the same thing. In the UK we say "if it isn't broken, don't fix it". Put it back please.

A Google User

RealCalc owns math I just wanted to find something better than the super bare-bones calculator that came by default. I didn't realise I'd end up going from a bb-gun to a 12-gauge. It does way more than I even remember how to do, so I'm confident this will be my last math app. :)

A Google User

Works fine but ugly Software works fine and I love the rpn mode, but wish there were some other themes to choose from. There really needs to be a 2 line scientific mode to show the entry and the result simultaneously. Pretty print would be a huge plus also.

A Google User

Binary/Hex mode broken This calculator only supports 3-byte binary numbers so you can't even convert a 32-bit hexadecimal value. This is useless as an aid for programming. Since this is the first thing I noticed, it wasn't even worth investigating the other features.

Efrain Santiago

Not worth it for long calculations It lacks something any scientific calculator should have, support for the screen to actually show you the equation you are writing and the order it is being processed in. If you plan to use parenthesis or any sort of exponent you will be disappointed.

User reviews

Thanks! After using the free version for some time, I took the chance of the 0.25€ offer to thank the developer for his work.

The best I used the free version forever but needed degrees and minutes so i upgraded. Best buy ever. fractions to decimal conversions and back. Considering a good scientific calc at the store could cost anywhere from $20 to $100 this thing is a steal.

Simply wonderful This is a thoughtfully designed program, and a real pleasure to use. It's restored my faith in software, after so much mediocre, buggy code.

Awesome & Handy Intuitive and powerful. Conversion tables are comprehensive, and I'm always using them. History feature is great, as is the retention of the last result.

Perfect, Best calculator app I have been using she free version for years. Just updated my s4 recently installed it. I don't really need to upgrade to the pro version, but I'm so appreciative of this app and how useful it has been over the years, that I just decided to pay for this upgrade. I will be using some of the functions of course.

Better than a real calc Most real calculators are a "can't find anything quick" jumble of keys, but not RealCalc, it's very easy to use and powerful. I use hex modes so I love the long press feature too.

Great calculator! I purchased to support the developers. Very handy in many ways. I have even used it for calculus homework. I have not explored all the features, but it has so far been everything I need. Nice interface, quick to launch. Very happy with this app.

Free one is good enough but.. I paid for it to support developer because it's so good. I use it every day at work. I like the option of full screen, and stay awake when in app. It reminds me of the calculator I used while at university. Results history is a feature I use a lot, and conversions. I'd like the option for a larger display area so parentheses can be used properly, as it is equations can't be edited on display line which is stops it being a complete sci. calculator replacement. the theme is fine don't change it!

This is an excellent scientific calculator, as well as simply a great calculator for everyday use. The button layout is great - the best I've seen.

Good value calc app Mainly bought this to support the developer as the free one is very good. but if we get any more good features all the better.I paid £1.99 less than the price of a pint of beer down at my local pub. Only bit im not so keen on is the about screen every time maybe only after an update would be enough and in a menu.

#1 because it is the best. It did not take me long to pay and get the 'plus' version to support the dev, although the free version is more than enough. It is so easy to use and has more functions than I will ever use. It is very clear that the developer is about building quality. Keep up the awesome work!

Listen Read Device Only Added Installed Calcularis: The only scientific calculator you will ever need.

A history feature will allow you to save as many equations as you need and allow you to retrieve them when needed or edit them. No need to press the = button because Calcularis is always calculating.

The full equation with multiple lines makes it easy to keep track of what your are calculating. All the standard scientific functions are on visible keys. There is a scientific and engineering notation mode as well.

Simply the the best free scientific calculator on the market.

The paid mode has the following additional features:

* applications such as Tip and split calculator, Loan calculator, math equations like quadratic equation.

* large set of constants

* unit conversions

* more functions accessed from the FN button

* more key layouts such as a 10 Key and Programmer/logical calculator accessed from the KEYS button

During the trial period (two weeks), you can use the features of the paid mode to try them out. After the trial period, the main features of the calculator will continue to work and will remain free.

Move over RealCalc, the new #1 Android scientific calculator has arrived. Some have asked the question whether you still need your TI, HP, Casio or Sharp calculators. The answer is yes. Phones are not usually allowed in the classroom or in testing centers. You will always need your old calculator for that. Plus calculators like TI-83, TI-84, TI-89 and TI-Nspire include graphing capability that is not currently supported.

•Multiple input fields except on small phones. This let's you do short side calculations without losing your place.

•Pre-packaged functions for quadratic equations as well as many geometric formulae.

•Buttons that store user defined functions that are created by binding an argument to a binary operator.

•Visualization of multivalued complex functions (roots, inverse trigonometric, logarithm)

•Visualization of quadratic and cubic functions

•Visualization of angles returned from inverse trigonometric functions.

•Complex numbers are very easy to work with, and all functions work with complex numbers where they are defined (inverse hyperbolic cosine, for instance).

•There is a fourth layout for small phones that is not shown in the screen shots.

•A unit conversion utility that lets you build arbitrary composite units. Conversion factors are written to the history, so you can bind the factor with multiplication to do the same conversion many times.

The layouts are designed to be ergonomic for each of four device sizes in portrait and landscape. Here are some examples of what we've done to make the calculator easy and speedy to work with:

•On small tablets in landscape, the keys are split so you can operate the calculator with two thumbs.

•On small phones, the numeric keypad is right under your thumb when holding the device with one hand.

•Square root, square, inverse and negation are all close to the numeric keypad.

•On small tablets, the long "NHN-1" button is a gesture recognizer that lets you scroll the six input fields with your left thumb. That way you don't have to let go of the device with your right hand to click an input field.

FAQ:

* If you want data size conversions in multiples of 1024, use kibibytes, mebibytes, gibibytes, etc - see en.wikipedia.org/wiki/Kibibyte.

* If the percent key appears to give wrong answers, make sure you are pressing '=' at the end, e.g. '25 + 10 % =' will give 27.5.

* If sin/cos/tan functions don't give the answer you are expecting, make sure you are in the correct angle mode. Degrees, radians and grads are supported, indicated by DEG, RAD, GRAD in the display. Use the DRG key to change mode.

* If any of the digit keys are disabled, or the decimal point doesn't work, or you have answers with letters in, or basic arithmetic appears to be wrong, then you are in binary, octal or hexadecimal mode. Press DEC to return to decimal operation. If you don't need these modes, please make sure that 'Enable Radix Modes' is disabled in the settings.

* If you can't find HEX, BIN or OCT modes, go to the settings and make sure that 'Enable Radix Modes' is checked.
