Good calculator since ... Use this app since Palm. Very useful and easy to use. Annoying bug: Keyboard clicks works 10% of the time on Galaxy S4 (under Kitkat). Rest is OK.

Dan Hansen

It's amazing! Simply the best advanced calculator on the market. It's practically a steal at this price. Do yourself and the developer a favor and pay for this app.

bd001217

One thing "missing" I love this app... the only thing I would add is a fraction function...you know, that a b/c button that lets you enter fractions. .. that would make it truly complete for everything I do... EDIT: hey, that's great news about fractions! Thank you for letting me know.

Tony Frank

Excellent Calculator... This app has been around since Palm Pilot days. .lt has proven accurate and easy to use. Flexible interface allows algebraic or RPN input,and it has financial, scientific, statistical, and conversion functions. It is a hidden gem in the Play Store.

Bryan Maret

Wonderful The best calculator app, by far (and I have tried many different ones). I have been depending on this calculator app for daily use at my job since my Palm Pilot days. The programmer's calculator pane with hex is much appreciated. This app is as good as an HP-42S, and that's saying a lot. Now if only they could get those real HP clicky buttons ;)

Sadik Jamal

Most complete RPN calculator Simply the best full featured RPN calculator available for android! It is well worth the small fee to go Pro!

By default, NeoCal will use Android settings for the keyboard click sound and haptic feedback.
Within NeoCal, go to the General settings page and choose "Always" for the "Key Clicks" setting to ensure consistent feedback. Hudren Andromeda Connection, LLC January 20, 2015

Great news! Fractions have already been implemented for the upcoming 2.1 release. Financial calculations will not compute number of years for a principal to grow to a future amount for a given interest rate. Gives error message.

Hudren Andromeda Connection, LLC December 4, 2014

We'd be more than happy to help you with this calculation but you must contact our support through email. Thank you. Simply the best. The Swiss pocket knife of calculators. Awesome. I missed this so much from my switch from palm. Developer is amazing and this calculator does everything.

Best calculator period I've used many calculators in my work and was never quite pleased with the interfaces. I love the interface and the features.Worth every penny!

Solid Calculator. Re-reviewing. Hope it continues to work in areas of restricted internet. Google material theme and iphone theme would be nice.

Hudren Andromeda Connection, LLC December 25, 2013

In response to your original review, NeoCal was corrected in August 2013 to ensure it would work properly when an Internet connection was not available. You've updated your review several times since then, but simply won't allow us to help you resolve your issues by contacting us directly. We'd be happy to help! Really! Almost Perfect Great calculator; everything I need except the ability to store multiple macros (programs); one is not enough. The multiple pages/interfaces concept is well-implemented, although it would be nice to "block out" those pages which I would generally not use.

Great RPN Calculator!! Best android calculator. I used it for Palm OS more than 10 years ago and then with Pocket PC and iOS. It is an app you can trust unlike some of the other calcs with little or no track record.

Lots of features... but many are not intuitive and hard to use.

Hudren Andromeda Connection, LLC July 5, 2013

A user guide is included with NeoCal which provides instructions and examples for using NeoCal. The best Dumped all my other calcs... This thing does it ALL.

Real calculator, not a toy What else could you want from a calculator? Good organization for function groups, scientific and financial calculations and enough programmability.

Really wins on the UI I use this in RPN mode. Rather than precisely emulate one of the great RPN calculators of old, this calculator actually makes good use of the fact that it is running on an operating system capable of a real GUI. You can bring up settings using the menu key. You can also swipe between screens giving access to different functions. Not that I don't appreciate a HP42s or HP15C emulator, but this is far more usable.

I have been waiting for this, the best calculator I have ever seen. I used it on Palm for years. It does everything & does it well. Period.

Really fantastic! If you're looking for a calculator that does everything (RPN, stats, trig, unit conversions, programmer functions, etc.) this is it! Nice UI and intuitively laid out.

I've used Neocal on 3 generations of personal electronics. Always excellent! Keeps getting better! Nothing else comes close!

## Scientific RPN calculator

My RPN calculator is a scientific and financial calculator inspired by the Hewlett-Packard HP-10C series pocket calculators of the 80s, most notably the HP 11C and HP 15C models.

These software version has borrowed the RPN (Reverse Polish Notation) and the look&feel of those calculators. It features classical 4 operations, logarithms, trigonometry, statistics, and macros for easy programming. It also features complete support for complex numbers along with 2nd, 3rd, and 4th degree equations solving.

Its unique magenta L key allows switching from one layout to another, thus saving space on small displays like smartphones without compromising usability.

Support for gestures allows switching from one keyboard to another by swiping left or right, and a light swipe up or down on a key executes the associated f or g function, without any need to actually press the f or g key.

See the web pages of the application at http://calc.lsrodier.net for complete keys description and samples.

My RPN calculator is compatible with all devices running Android 2.1 and up and supports both horizontal and vertical orientations. It does however requires a device with a minimum screen resolution of 320x480 (or 480x320 according to orientation). Note that tablet screens 1280x800 are properly managed.

Summary of the main functions:

* RPN input

* Portrait/landscape and multi-resolution layouts

* Gesture support for extended/simplified inputs

* Arithmetic functions (+, -, x, /, 1/x, +/-, etc)

* Trigonometry, logarithms, hyperbolic trigonometry

* Percentages (+, -, variation, total)

* Dates

* Complete complex numbers support

* 2nd, 3rd, and 4th grade equations solving

* Unit conversions (temperatures, distances, etc)

* Macros for simple programming tasks

Summary of the main statistical functions:

* 1- and 2-variable statistics

* Sums (Σx, Σx2, Σy, Σy2, Σxy)

* Mean, weighted mean, standard deviation

* Linear regression

* Correlation coefficient

* Linear estimation

* Statistical registers table

## HP-35 Emulator Calculator.

The HP-35 was the first scientific pocket calculator in the world (with exponential and trigonometric functions). Also used Reverse Polish Notation (RPN), being the first scientific calculator algebraic history.

And now through this emulator for the HP-35, where both perfectly emulates the LED screen of the original 15-digit calculator physically and how we can make use of it in a virtual like you're actually physically in our hands through our Android device.

The HP-35 calculated arithmetic functions, logarithmic and trigonometric functions.

And now through this emulator for the HP-35, where both perfectly emulates the LED screen of the original 15-digit calculator physically and how we can make use of it in a virtual like you're actually physically in our hands through our Android device.

The HP-35 calculated arithmetic functions, logarithmic and trigonometric functions.

Some historical curiosities of this calculator are:

- The display of 15 characters in the HP 35, when the reverse was seen, could produce a limited number of alphabetic messages. For example, 710.77345 would read as "SHELL OIL". The sample was probably more extravagant +40 57738.57734 E would be read as "Oh Hells Bells".

- The HP 35 was just 5.8 inches long and 3.2 inches wide. This was the pocket size of William Hewlett, of there as the "pocket calculator".

- The power requirement of the LED display was responsible for the short life between battery charges the HP 35, about three hours. To prolong the operating time and prevent damage from overuse of the slide switch on / off, users could press the decimal point key to force the display to illuminate only a segment of the LED.

- The HP 35 calculated arithmetic functions, logarithmic, and trigonometric, however, full implementation used only 767 carefully chosen instructions (7670 bits), in what is a marvel of concise programming.

- The introduction of the HP 35 scientific calculators and other similar capacity by Texas Instruments soon signaled the end of the slide rule as a status symbol among science and engineering students. The covers of the rules of calculations were disappearing to make way for the covers of the "electronic slide rule", and universities began to abandon the slide rule classes of their curriculum.

- The HP 35 was the beginning of a family of related calculators all sharing similar mechanical packaging:

- The screen was unique in the sense that multiplexing is designed to illuminate only one LED at a time segment, instead of a single-digit LED, because HP investigations had shown that this method was perceived by the human eye as more Bright energy equivalent.

- The calculator used three NiCd batteries "AA" assembled in a removable battery pack, owner of HP design. Battery packs and replacement are unavailable, leaving 35 HP depending existing alternating current, or the users must rebuild the battery pack using batteries themselves available. An external battery charger was available and could also function calculator from charger, with or without batteries installed.

Internally, the calculator was organized around a serial processor chipset (a bit) floating point number processing 56-bit, 14-digit numbers representing BCD.

It was introduced at a price of U.S. $ 395.1 and was available from January 4, 1972 to 1975. During that time over 300,000 units sold.

Before the HP 35, the only practical portable devices to perform trigonometric and exponential functions were slide rules. At that time, existing pocket calculators had only four functions, ie could only add, subtract, multiply and divide. Originally it had been known simply as "The Calculator", but Hewlett suggested that it should be called the HP 35 because it had 35 keys.

HP 35 was developed in two years, HP 35 was released in 1972.
