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 ads 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 ads permanently for a small fee via In-App purchase.}

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

Hallo Seit einiger Zeit werden trotz der Einstellung „Normal“ die Zahlen immer mit Exponent dargestellt.

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.

You should add a calculus calculator, linear algebra calculator, and probability. I love this calculator app

This is the best calculator i have used on iOS for over 4 years. Behaves like good old Casio fx82 and its peers. Has 7 modes that can serve all use cases except financial. Keys are well organised. There used be an annoying ad that would randomly come and go causing the key layout to move up and down causing lot of mistyping . From the time that ad stopped being shown this is simply the best calculator.

wie ich es v. Alexander gewohnt bin, ist auch dieser Taschenrechner sehr praxisgerecht und alltagstauglich umgesetzt 👌👍. Was ich u.a. besonders schätze ist die einfache Umschaltbarkeit auf verschiedene Anwendungsbereiche wie z.B: Zeit hh:mm::ss nach dezimal u. vice versa 👍. Verbesserung u./od. Erweiterungen gibts auch immer wieder mal bei ihm 😁

This review is a mixed bag. It's a decent calculator - but it looks like a jar of sugar candy sweets found long ago in the tuck shop near my first school! These days - and based upon appearance alone - it's not tasty enough, and has been expelled from the over-subscribed maths class of my iPad. However, I should pay tribute to the developer for dedicating time and effort in producing what is actually a very capable calculator, for free. …Oh, did I forget to mention the intrusive advertising? That warrants a further reduction of one star. And for that reason more than any other, Kalkulilo; you are hereby dismissed…
