Needs better support for tablets.It's high time developers started caring about tablets. This is a productivity app and is best used on large screens anyway.

Nice app with bad in app upgradeI sort of liked this app and wanted to get ride of the ads. So i discovered they have an in app upgrade. Isn't it the time for developers to understand that's a bad business model?

ProfessionalThis app accurately graphs many useful trig functions and can literally be directly used to solve equations. The UI is simple and unbloated, any Aspy will tell you, clever work!

Full disclosure givenThe need for internet connectivity for the free version is clearly stated. If you do not like that, don't download! Otherwise why complain? Best app of the type you can find.
