Good Learning
It isn’t the most beginner friendly application, but it is still okay. It is really good for people who already know a language.
At the bottom of most lessons there are sources to learn more about a topic. The application does a quick overview of each thing, and the sources help people learn more—especially when they have a hard time understanding it.
If you look in the reviews, you can see responses from the developers. That shows that the developers are active and do the work to help you.
In the comments section within their application, developers and users (some experienced) do respond to questions, so if you don’t understand something, you can just ask about it.
Even if the application doesn’t always give the best exemption of f things, it still gives very useful information that is hard to find elsewhere when you don’t really know what you are working on.
Some people have given some silly negative reviews, like “it is only learning and everything else must be paid for.” The truth is, the application was made for learning. It doesn’t matter if they want to include extra that must be paid for. The main application is free, that should be good enough. Furthermore, the developers need to make money (especially considering that the apple software for programming applications is $90 a year).
