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.
- Fixes an issue when copying a binary number with 64 Bit into the clipboard.
- Fixes an issue with unresponsive switches in the settings.

I loved this app, I truly did. Until... I updated it.
This app has been extremely useful and totally user-friendly, but the new interface... I don't know why it had to be changed. This app has helped me through physics, biomechanics, chemistry and other functions that entailed a calculator.
I want to thank this app for everything, for being the best and absolutely free. But now I think I am sticking with the Calculator+ app. For those who like editing and dislike ads, this is the app for you. Bye and thank you again. I thought updating should move the app forward, make it better and not regress.
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!
Just what I needed!
I'm visually handicapped, and I've looked all over for a decent, well-designed calculator with the functions I need. The contrast on the button layout is helpful.
In earlier versions, I was annoyed by some rather poor VoiceOver support. It seems to have improved greatly, and as a bonus the developer has now added support for the Apple Watch! What's pleasing is that the Apple Watch support is actually well thought out. It works far better than other calculators I've tried on it. It was immediately usable and I am highly appreciative of that.
I've finally reached the point where I am deleting the other calculators I use. This app now does it all for me, and does it well.
