Magic Calculator 4+

Excellent

I love this app. It does exactly what I need without being overwhelming in it's display of ability. Also the author is very responsive. I submitted a suggestion and not only did I get a response from the author, within a few days the suggestion was implemented in an update. That responsiveness is priceless.

Univariate plotting lacks features

This app offers a clean and responsive interface for quick plotting and visualization of univariate functions, potentially offering a replacement for Grapher. For my preferences, however, the "Graph Window" would ideally feature more varied zooming functionality besides hard-coded axis limits and "Zoom fit", such as a slider control for the zoom level relative to some user-specified reference. The typed axis limit feature could also be improved by allowing for user-defined variables or native constants such as "pi" and "e". (Currently only real scalars seem admissible.) Finally, users may like to specify the linewidth of plotted curves, which look way too thin on my 16in Retina MBP display (running macOS Catalina). Thanks for considering implenting these features.

Respuesta del desarrollador ,

Thanks for this feedback.
Regarding the grapher, you can already zoom in and zoom out by scrolling up and scrolling down, and move the displayed area with a drag and drop.

Fantastic Calculator

I'm so happy I found this app. I have been using Soulver for a couple months but I needed something that had more precise calculations. I almost gave up on finding a good alternative until I found this app by chance in some blog post from 2013. At the current price, it is absolutely worth it.
