Update needed After choosing to display the graph x^2+y^2 thep app crashes my phone SGS4, upto the point thah hard restart, by holding the power button, is needed
Very helpful but... Great app! Extremely helpful. But there are repeated, and sometimes incomplete facts. Also, in the math section, lots of definitions and explanations are cut off. And for some reasom, the game thing will show the queations AFTER I enter an answer. Because of this, I can't play the game properly. Please fix all these errors and I will rate it 5 stars. This is samsung galaxy 7.0 plus BTW.
Changed my rating: very good I've just changed my rating. This app has lots of good info, and even a scientific graphing calculator. The interface isn't the nicest, and the section on "celebrity" facts could be removed.... (who looking for math formulas cares about Britney Spears?). The translator doesn't work. Always returns "Error: translation failed". But what is a translator doing in a math app? It can be removed as well, as there are other apps such as Color Dict and Golden Dict that have this and are more appropriate. I'd rather have this app smaller than have useless ("celebrity" facts) or redundant (translator - already in other app) tools. The bad part doesn't affect the great part, so four stars anyway.
It's a demo Do you really want to study math with ads flashing at the top or bottom (it alternates) of your screen? So distracting! They think the ads don't steal enough screen real estate, so you also get a zoom in/out bar to steal a little more. And there is a nag screen that pops up over and over and over... Maybe the paid version is good, but this one is awful. Promptly removed from my phone. Oh, wait, I just checked the developer's profile. There isn't a paid version. So this is it! A study app with ads flashing... What a terrible idea.
Advertisements destroys the fun Adds cover up the screen hence smtimes its difficult to get a full view of the facts or smthing related to the app Plz fix this
Best ever Superb. Easy to use, full details, math game, facts, everything is awesome. Only a problem with my handset (htc wildfire) is that i cant read whole fact page if it excids the screen. Can't scroll the page.
added hardware acceleration.
