Kalkyl 4+

The Best Calculator App

This calculator is fast, ad-free and elegant. It takes up almost no storage and looks similar to the iPhone calculator (which is why I downloaded it).

Apple Watch support needed

An Apple Watch support would be cool.

Developer Response ,

Hi!
I'm sorry to say that as a small indie developer I currently don't have the resources to create a really good user-experience on both platforms and will continue to focus on perfecting the iOS experience for now.

For the time being i'd recommend that you use one of the other calculator apps for the Apple Watch.

graph control difficulties

it is very hard to control the veiw of the graphical interface with very small solution like −(x−2)^2+4. i would consider getting pro if this graphical issue wasnt frustrating. would also be a huge avantage to be allowed to long press numbers to easely change the last digit to the selected power or fractionnal form

Answer:
That pinch that you say if very frustrating i would send you a screen record if i could. A soon as the data gets very dense it is very hard to zoom in i have to let go both my fingers at the same time to even get some hope of holding the way i zoomed in.

Developer Response ,

I hope I get you right here, if not please send an email through the app.

Try to long-press on the keyboard to move the cursor with high precision.

If you have issues with the graph, you can pinch to zoom. Not sure what you find problematic there?

Edit:
Now I see. That’s a bug! We’ll fix that.
You should be able to transition freely between one and two finger pinches, without the graph jumping.

Edit 2: this issue has been fixed in 2.9.1
