    What saved me from giving up

    I spent weeks trying to follow old tutorials that just gave me errors and ended up losing motivation; with this course everything was different because they really explain the why behind things from the start, it's the push I needed to stop copy-pasting code and actually understand what I'm doing on my screen.

    I've got my own app!

    It's an incredible feeling to see something you built yourself installed on your phone. The content is really engaging and it motivates you to keep creating more and more things. I feel like I learned exactly what I needed to start playing around with my own ideas and turning them into real applications without unnecessary complications.

    My gateway into the Android ecosystem

    What I value most is how Android's features are broken down so that, even without a huge background, you end up building working apps. It's motivating to see tangible results from the earliest sections of the program
