Duolingo iOS update available [05/05]
Updated version number to 4.0.1
Officially brings back practice weak skills, unofficially I noticed some animation transition changes between questions.
I still can't fathom why they removed that -- but I do hope they add that back. And, I'd love to see the old goal system return rather than this new one that lacks any way to get ahead. Many days I can do 40XP, but sometimes I'd love it if I could do 60 the day before and 20 on a really hectic day... That was such a nice feature.
Excellent update—a very smooth re-integration of the practice skills feature. Duolingo has become a remarkable example of robust performance and clean design. Everyone on the team should be quite proud of what you've accomplished!
Earlier today I enthusiastically recommended Duolingo to someone with complete confidence that they would be surprised and delighted. Well done!
