Poor functionality
Very disappointed and i made the mistake of paying for a year to get rid of the ads - which you can’t actually get rid of. It has the frame of an educational tool, but is poorly designed. A wrong answer on a quiz will freeze the app on an error message that can’t be closed out of. The calculator is very clunky. I can’t even imagine trying to use it to solve problems largely because it is difficult to navigate. There are formulas and concept descriptions but they are poorly worded and there is minimal explanation of the principles. I am afraid the developers of this app are more interested in making the app seem like it will be useful if you paid for it. It is not.
