One drawback need to be corrected.

It is a useful app, BUT it has one huge drawback: there in NO INDICATION of "le", "la" which are the french equivalents for "the".
As French makes a distinction between masculine and feminine objects, people use "le"/ "un" for masculine things/persons and "la"/ "une" for feminine things/persons.

When learning words in French it is crucial to learn them with gender understanding ("le"/"un" ,"la"/"une" before every noun).

Without understanding what gender the word is, you will not be able to construct phrases and sentences correctly.
You may sound awkward.
