This makes learning Spanish much, much more fun and effective. Great job Duolingo team!

Amazing product. I use this daily and the CBT approach makes enough of a difference that I'm convinced of the value here. The only thing missing is randomly timed reminders so I can catch moods throughout the day vs. set-time reminders.

Beautiful design. Once this app has better notification features (multiple notification times, randomly timed notifications, etc.), easily 5 stars.
