Option to Strengthen Skills in iPhone app like on web site
On the web site there is an option to strengthen skills which will give you a variety of exercises and words. And doing this helps to build multiple skills at once with an element of surprise but the iPhone app doesn't have that. I have to select the skills I want to strengthen. Please add this feature to the iPhone app.
On the latest version of iOS:
Click "Practice" (bottom middle option)
Click "By Yourself" (third option)
This will give you the "Strengthen Skills" (without a timer) option.
If you want a more timed experience, select "Play a Bot", this is not exactly like the timed practice, but has a similar feel.
Not on my iPhone it doesn't. All I have at the top right of the screen is Profile options. Is it the iOS app you're talking about?
Mind you, I just looked and cannot see how you can do it on the web! Maybe I am missing something (I almost always use the app for learning).
