Kalkyl 4+

This is one of the most straightforward and useful calculator apps I’ve ever used, but can you guys please add back an option for the Kalkyl app to be dark mode independently of iOS 13’s Light or Dark mode?

Prior to iOS 13 the Kalkyl app always had a dark background and I loved it but now it changes to a light background based on the system’s dark or light mode.
The light mode makes the app less appealing and harder to use for me, so I would appreciate it if we got a manual toggle for independent dark mode on Kalkyl.

Thank you for feedback!
There's now a system theme override in settings. 🤞🏻

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!

Thank you for your review! 😊

I believe the shake to undo issues you were seeing got fixed in the 2.6 update. If not please reach out via the app.

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. 🤞🏻
