Is Learning Mobile Development Too Frustrating?
I was in your exact situation. Jumping from one YouTube tutorial to the next one, just to find out it’s not what I searched for. Or fighting myself through Google (and let’s be honest - if you visit page 2, you know you’re lost).
And while AI nowadays seems like a blessing to learn, it can also quickly put you on the wrong path. As someone learning development, you aren’t in a position to know which part of the AI’s response is correct and where it tells you complete bullshit - and believe me, this happens way more often than you think.
When you then think you finally understood something, you’ll face your next enemy - big tech companies like Google who push new shiny technologies faster than you can look. How the heck should someone keep up with all these changes, new policies and endless discussions about which way of building an app is right?
I can understand you by 110%. It’s just as frustrating to me. And that is why I made it my mission to help mobile developers like you to learn just what you need for the real industry out there. I won’t waste your time with theoretical BS you won’t ever need. Instead, I’m hyper-focused on giving you practical advice & strategies you can instantly apply. While most other instructors often just make you type off their code, I’ve made it my goal to explain the why behind every single line of code I write write. Only this way, you’ll find your confidence making jumps you didn’t consider possible before.
Philipp Lackner has over 14 years of experience in the software field. Over the past years, he built a following of over 250,000 developers on social media who trust his work. With over 25,000 sold copies of his courses and 1,000h+ spent for teaching Android concepts, he already helped hundreds of thousands people to learn practical skills they can immediately apply.
He has a degree in computer science, however it didn’t go as expected. The amount of theory that was taught in university made him think about a better approach to learn what is really needed in the real world. Over time, Philipp found mentors who taught him exactly that in a practical setting. That was the game changer for his career.
After having worked for dozens of companies around the globe as a consultant, Philipp now wants to teach other Kotlin developers what really counts for becoming an outstanding developer in today’s competitive industry.
