No support, bad explanations and needs improvement

Crap crap crap!!!! Was disappointed with the lack of rule explanations!!! Also they dont email you back, so no tech support. The app is 60% complete... They need more information to back up their calculations... On a few equations, I found incorrect quotients and products. When you combined this app with 5 other math education websites you can figure it out for yourself but I shouldnt have to go search for the information.... Boooooooo
