I love this app. Been using the pro version for years. However in the free version the ads make the app run poorly and display of calculations is delayed while the network connection is checked and the ad updates. If your network connection is down our temporarily unavailable the app throws an error and is completely unusable. Having said that however, just get the pro version, it's worth every cent - you do not wanna bypass this app based on the free versions quirks... AWESOME!!!

It is help full. One thing is a bit annoying is that you cannot choose the scale for axis to have different magnitude

I think this app is such a great tool and we should have it installed in our engineers smartphones. I'd like it to have some more features like to plot discrete time functions, as well as Matlab does. Boolean algebra, Karnaugh Maps, are other useful features for electronic engineering degrees that could be strong useful. Thank for your efforts.

Great app. The spare graph sheet feature and the ability to graph 2 or more functions on the same graph makes this thing really awesome. Steps shown in calculation by the calculator also prove to be helpful very often. Just allow us to change the scale to our requirements.

It is a very good app . One thing is there that is , in the calc , although , I can zoom in , I cannot zoom out , so I cannot see the whole calculation at once . Plz fix this .
