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, including legacy ones
- 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.
The user interface can be customized, you can change the key colors for different categories of functions and operators which helps to distinguish and find these more easily.
The App also includes calculator widgets for the homescreen which allows to do calculations directly from your homescreen and a calculator for the Apple Watch.
I love this calculator. The only problem I have with it is when you are working in scientific mode then switch to bit mode the number doesn’t transfer over correctly. Even when it’s an integer. Is it in floating point representation or something?
Excellent, stopped working on Apple Watch OS26

I love this calculator for the ability to have some scientific calculation available on the Apple Watch. (Revised) It required a re-install after upgrade to watchOS 26 to have it work on my watch.I particularly like the variety of modes and the ability to do math in any number system, not just binary, decimal and hexadecimal.The size of the keys is also reasonably sized despite the functionality. I am basically using it as my primary calculator all the time
Extremely functional

Years after first finding it, this continues to be my default calculator on iOS. It’s easy to use, doesn’t push ads, and has any and every feature short of actual graphing that you might need to do some quick math.
Excellent calculator!

This is my go-to calculator for iPhone. It has everything you need for scientific, bit/integer, and statistics. I feel it was written for programmers. There are many cool options such as adjustable bit depth, etc. The negative reviews complaining about ads should pony up the money and buy the app!
- Bugfix: When storing a number (which was directly entered and not the result of a calculation) to the memory it was not possible to immediately enter a new number. The existing number was extended instead. This is now fixed.
