They cares about payment first without showing any introduction about the subject. I already purchased , it's very short and there's no any examples.
once you get in you have to pay for the lessons.
Looks good but not actually free
I love it already
The first three lessons are free. But the remaining 10 are $.99 EACH!!! they should be more upfront about this.
Same content only different layout. Even the examples are the same...wording and everything. And like WAGmob it assums knowledge and doesn't explain the terms it is using.
It's a great app for practice
Liked it very much awesome app
