The letter ה (hey) is often at the end of a feminine word, and it's usually added to masculine adjectives to make them feminine. In a grammatically correct sentence, when an adjective modifies the noun, the gender of the adjective tells the gender of the noun.
The letter ה is also at the end of some masculine words, so we still have to learn the gender of each word.
I feel a phonetic spelling out of the words would help in this program, with perhaps a seperate section just for learning the writing system. I ran into this issue years back in learning Russian. Its difficult, at least for people like me, to multi-task in language learning.
