New colors are terrible
Not only are the standard colors now terrible, there is no option to revert back to previous patterns. You have to select individual groups of keys to change. And the options to change to are still terrible. My eyes hurt just looking at this.
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

Excellent, stopped working on Apple Watch OS26
I love this calculator for the ability to have some scientific calculation available on the Apple Watch. However the app does not load on the Apple Watch Ultra 2 after upgrading to OS26 anymore. Still works fine on the iPhone under iOS26
Crash with iOS 12
Ver 5.1.3 crash with iOS 12 on iPod touch v6 too.
Brilliant App
Full suite of options, fast and reliable.
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.
Calculator
You should add a calculus calculator, linear algebra calculator, and probability. I love this calculator app
Excellent rapport qualité-prix
Pratique et performante !
Best calculator on the App Store
I saw that this calculator had only two reviews so I just felt compelled to write a review myself. I’ve had Kalkulilo for 5 years now and it helped me immensely through a computer science and math degree. If you care about math, you will appreciate the vast array of functions and different types of calculators, like one with selectable number base systems from 2-36. It can do everything but graph. And even if you don’t care about math, I find the time calculator that can do arithmetic on hours minutes and seconds often useful on a daily basis. I recommend this calculator to everyone, but especially people who do lots of math and need a diverse calculator.

My favorite calculator
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?
The best calculator
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.

Very good!
I tried many calculators, this is one of the best I tried.
Sehr vielseitiger Rechner mit kleinem Mangel
Durch die verschiedenen Betriebsarten und der Möglichkeit, im Querformat zu arbeiten, eine tolle App. Super wäre allerdings, wenn die Ziffern auch über die Zifferntasten einer Tastatur eingegeben werden könnten - kann aber auch keine andere Rechner-App…
Useful and good
A really good and useful app when you dont have a normal calculator by your hand

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…

I raise you this wonderful app and challenge you to show me another one with 11(!) years of continued support and regular updates. Love it!

I paid for this, but now there are ads. Hrmph.
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!
