i like it... A lot! ,

Favorite calculator for classes

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!

Thank you! 🙏🏼

I’ve been looking into the power consumption and everything points to very low energy usage in 2.7.

The only thing I can find is if you’re using an iPhone with an LCD-display then the dark colors used actually draw more power than light colors, and it could be that the display is on for extended periods of time while studying. I’d recommend turning the display off when you are done with the calculations, and see if that helps. Maybe it helps, maybe it doesn’t. 😊

If the problem persists (or if anyone else reading this is seeing the same thing) please check the Settings app > Battery and see how much Kalkyl really draws. Then contact support at contact@nordic.io and we’ll figure it out together. 🤞🏻

Nice app, screenshots misleading

The screenshots in the App 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 the app because it seemed so fundamentally flawed in the screenshots. Once I did download, I see that it graphed correctly. Nice app.

Thank you for your review!
The values are actually correct in the App Store screenshots, it’s just that they are cropped. (-1)0 to the left and 1(0) to the right - still, it does look a bit confusing! :)
Have a great day!

Great alternative!

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 this app. The feature to swipe down on the = button for previous calculations is gross.
