Kalkyl Reviews

Missing two basic functions
-No clear button or short cut
-No search function in support

Why is everything shoved on either side of the screen? And where is the clear all button? And why does it display the calculation changing as you type. Weird…

Overall this is a great calculator that I would definitely recommend, especially because it’s free! As another reviewer said I liked it so much that I deleted the default one. The only flaw is that the shake to undo is finicky at best. Other than that, amazing app!

Kalkyl would be perfect if it worked with split view on iPad. Let me clarify, technically works, but when you try to use it the whole keyboard comes up so it takes up 75% of the screen, defeating the purpose. Besides that, its great!

Needs a clear all button

Nice, clean and simple. I love it. I wish there was a way to do % on it with the % button. I hope it is available in a future update.

2206*(0.67%+1.17%) error result
If it can not parse the expression, you should give the error message instead of the error result.

Very convenient and easy to calculate $ / KWh etc. for a solar electric project !!! Thanks !
Also for utility gas bill calculations.
Great calculator !!! Thanks !!!

I love this Calculator. Thank you so much to the developer for lowering the required iOS version to 11.0... I really appreciate it.

Finally a scientific calculator app with normal exponentiation carets! I really appreciate what you’ve done making this free of adds and in-app purchases. Forever thankful!

Still the only calculator app I use daily. Love how easy it is to make a quick graph.

The screenshots in Kalkyl Store for version 2.2 refer to graphs that appear with x axis min value 0 and max value 1, listed as 0, -5, 5, 1. I suggest zooming out for the screenshot so that it shows the correctly graphed values (-10, -5, 5, 10). I almost didn’t download Kalkyl because it seemed so fundamentally flawed in the screenshots. Once I did download, I see that it graphed correctly. Nice app.

It just needs a clear button and it will be way better even though it’s the best calculator I know about so far

I very rarely leave a written review but this Calculator has single handendly improved the quality of my life out of any app on my phone. It is SO useful to math out stuff on the go as well as having a graphing calculator built in. Thank you so much for making this <3

I used this calculator almost everyday in my physics class. It helped a lot on class assignments when my actual calculator went missing.
If it wasn’t as power hungry on the device (I think that’s iOS though, since that’s also present in the stock app to a slightly lesser extent), it’d be even better. I do kinda wish there was a landscape view similar to the iPad’s implementation of orientation on larger iPhones. Overall though, it’s my favorite calculator app on iOS!

This is what Apple should have done to begin with. Really great calculator, simple, but very effective. Could use a history feature, but honestly it’s still the best. Thank you for keeping it free.

Great replacement for the standard iPhone calculator. Excellent support. I reported a problem and it was fixed the next day. I’ve evaluated many apps for my iPhone and this one is the best by far.

Kalkyl is very useful and the layout is super simple and easy to use. Although it would really help if you could make use of multiple variables. Maybe this could be made possible in a future update.

This is how iPhone built in calculator should have been at first place. 3D Touch, Haptic Feedback, 3D Touch cursor function all these basics which didn’t do with their built in calculator app are all present in Kalkyl. The feature to swipe down on the = button for previous calculations is gross.

Incredible calculator app, much better than all other calculator apps I have tried! Easy five star from me. I would give six stars if I could.
