Great program that has and is helping me immensely. Four years [studying Spanish] and after just a couple of days with this app I finally am 'getting' the verb thing into my head. After the first couple of lessons I finally feel comfortable conversing with the natives here in Panama. I still have a long way to go but this application was the key for me. Thank you!
