All the information on this app is available on YouTube with animated videos with narrators who dont sound thirsty (literally swallowing after every word) and creepy voice in you ear (if u wear headphones). Also u have to keep paying $10 per set of 10 lessons... Theres like 150 lessons, so u do the math. This app fraudulently made me believe that $10 buys u all the lessons. Shame on this company.
