The app is perfect not only if you speak Spanish for 10 years, but also for beginners. Check out the difficulty level - you learn colours, seasons, family members, hobbies, flora&fauna… Doesnt seem too hard, I guess. Of course this memorization tasks couldnt give you the whole language environment - grammar, word order things you have to learn by yourselves. As for me, I found this app very useful while studying Spanish with teacher. I learn words faster and they dont slip off my mind after I close the app. This app is not a magic tool that makes you speak Spanish from the 1st lesson, but its a good assistant if you take the learning of foreign language seriously.
