"Tips and Notes" should be in the app.
Thanks for the amazing website and also the cool app. I would like to suggest that you also include the "Tip and Notes" section in the mobile app (for apple, I don't know if it is already included for play store).
Thanks for taking my suggestion and keep up the good work.
This has been raised before many times over. For example, I added my support in this discussion:
I also got a dig in on this discussion too:
Where I stated:
But to be honest, I'd like to know why the apps are the poor relations to the website? Examples; there is no discussion option (except on individual phrases), the amazingly useful "Hints and Tips" are completely missing from App version, progress information is better presented on website - such as how many XPs are required to reach the next level.
In all cases, I am specifically talking about the Android version of the App. But I wouldn't be surprised if this is applicable to the iOS versions too.
Hopefully one day, the guys at Duolingo will take note and put the hints and tips in the apps...
