Ratings and reviews

Stack depth is surprisingly limited. For example, it's not possible to input a standard calculator forensic, asin(acos(atan(tan(cos(sin(9)))))) because by the time you get to the inner cosine, it won't let you input anything further. Most textbook entry calculators permit deeper nesting than this. The new complex number support is a welcome addition (no pun intended).

Graphing doesn't work. I entered 3 equations, hit the graph button, and after a 3 second delay, a blank graph appears. I tried very simple equations (y = 2x, y = -x, etc), made sure the minimum and maximum axis values were appropriate (-10 to 10 on both axes), and it won't plot the graphs. I'll try a different app.

I like it! Vibrate on keypress would be a nice addition. I also have some small issues where selecting a previous result shows an empty pop menu when in darkmode (switching darkmode also shows the let's get started menu again). The up arrow also does not select the previous result.
