Kalkulilo (scientific calculator)

By Alexander Clauss

Open iTunes to buy and download apps.


Kalkulilo is a comfortable calculator program and offers several different modes.

- The scientific mode offers all the usual functions and operations like the basic arithmetical operations, power, logarithm, roots, trigonometry etc.

- The bit/integer mode offers logical operations (AND, OR, XOR, >>, etc.) on bit level. All values can be displayed as binary, octal, decimal or hexadecimal numbers. Calculations can be done in 8, 16 32 or 64 bits.

- In the statistics mode you can create a sample by adding several values and then calculate mean, median, quantil values, variance, standard deviation, range etc.

- Trigonometry mode provides lots of trigonometric functions

- The base/radix mode allows you to do calculations with numbers of base 2 to base 36

- The Time mode lets you directly work with time values (hours, minutes seconds)

- A simple calculator is also included, with just the basic operators and large buttons.

Colorized keys will help to distinguish between the different categories of the functions and operations. The user interface (design, colors) can be customized.

The App also includes a calculator widget for the notification center and a calculator App for the Apple Watch.

Note: This app uses iAds to generate revenue to cover the costs for developement and support, and to be able to provide the App for free. But you can get rid of the iAds permanently for a small fee via In-App purchase.

What's New in Version 3.5.1

- This version includes much more detailed accessibility labels for VoiveOver (for the App, Widget and Watch)
- Bugfix: A button in the Watch App was linked to the wrong function.

A Pleasure to Use

Start with a full function calculator that has every mode you might want, including scientific, statistics, trig, binary, even a mode for time and circular angles such as latitude and longitude.
Now add a customizable user interface that is not merely useful, but beautiful, and this wonderful app is what you get.
I especially love being able to easily find different groups of functions by setting them to different colors, like pink for memory, green for trig, and greenish blue for roots and logarithms.
The buttons and number display are very easy to read even on a small iphone.
This is one of my 'must have' apps.

Watch app not quite ready

Noticed the app showed up on my watch after the last update. As a basic calculator on the app it seems to be good on the 42mm watch.. one problem that makes it unusable is that the number 9 button on the app is mapped to the number 8!! So when you push 9 the number 8 comes up (not a pudgy fingers problem).

A great app!

This is the best calculator app I've used. It has modes for bit/integers, statistics, trig, etc. Basically, it's a well developed app that I use almost daily.
