In the app, it gives you one entire course for beginners. Then you can take another course with lessons you can buy using bits (which you buy and earn). But, you cant even see what the code in the lessons is doing without paying! There is a "Tap to try" button thay you need to pay for! Not even basic learning is allowed without a membership. That cannot be so with a free app with paid extre features. Seeing what the code does is not an extre feature. I'd buy the membership if this wasnt the case
