I would have given this app 5 stars, but there is a major bug which could be fixed. When you expand some results using the "Show step-by-step" option, sometimes the steps are invisible on the screen. I know the steps are present because (1) I can download an extremely blurry image of the steps, and (2) I can copy the text of the steps and paste them into a separate app and the text is all present. However, in the app, the step-by-step solution can't be seen. This is a major bug, because the beauty of this app is the ability to see how solutions are derived as to understand the concepts needed to solve specific problems. Typically, this problem occurs when viewing complex differential equation solutions which involve many steps and substitutions. Please fix this rendering problem.
Whenever i write a sentence on the search bar, it doesn't do anything immediately but i have to clickon the search bar one more time to start the computing process. Apart from the predefimed examples, personal queries doesn't show the definite result
The step-by-step solutions don't show up, but I can save a blurry picture of them, which isn't really helpful. I bought the app specifically for this feature!
Finally they implemented a history function and made a complete rehaul in general. Was about time! Step-By-Step-Solution sometimes doesn't display anything though
So useful even outside of School.
Supreme knowledge of the universe!!
