Common complaints

• ✗Interface issues after design update (expression validation failures, navigation inconvenience)10% of mentions

  «After redesign it became unusable... it doesn't evaluate expressions with functions at all. To the point where after typing Sqrt(2) it writes '2.0sqrt'. Instead of a list of used functions, now there's a list of all Wolfram functions»

• ✗Incorrect calculations in some operations (derivatives, systems of equations)10% of mentions

  «It calculates the derivative d/dx(cubic root of x^2) incorrectly... It cannot solve a system of linear equations»

• ✗Lack of full Russian localization makes it harder to use20% of mentions

  «Russian language is really needed to understand the formulas. It's quite a powerful calculator for those who know English mathematical terms»

• ✗Computation precision limitation (maximum 5 decimal places)3% of mentions

  «5 decimal places maximum»

• ✗Inconvenient behavior after pressing '=' (continues input into result instead of clearing)3% of mentions

  «After calculation (pressing '='), the application continues to input data into the result instead of clearing it»
