Just a question - Do you use duolingo or another app to learn a language? --

Yes, I've tried "Duolingo" and I didn't really like it. Why? 1)  It punishes you for not using it every day, and I learn when I have time during the week; I just can't every day. 2) It is tedious. I can learn a lot more by  just reading online in my target language and using a bilingual dictionary and a site like forvo .com that lets you hear how words are pronounced. 3) The English translations ( my native language is English) are not always very good, so its not clear to me what I'm supposed to be learning. 4) by the time I completed the unit ( which took me almost a year), I felt that it had been a complete waste of time and I hadn't learned anything.

I havn't really found any good apps, and I must have tried at least 10. I guess Duolingo is probably one of the better ones, but thats not saying much.
