Philipp Lackner Arvostelua 

Love the in depth explainations provided by the Philipp which truly is require to understand the concepts.

I'm a retiree who took up Android app development for fun thanks to Philip Lackner's excellent tutorials. Now I'm interested in the inner workings of Android and I also want to understand the Kotlin language in detail. That's why I recently bought Philip Lackner's two courses, "Android Internals" and "Kotlin." They aren't theoretical courses, but excellent practical ones for truly understanding the coding and functionality of Android and Kotlin in depth.

Philipp is a very good teacher. I think he always strives to deliver the quality content he promises from the course preview. Personally, I haven't submitted any questions in his courses, but that's because other developers like me ask them and he or his team answer them, which is fantastic. Overall, his explanations and content have helped me a lot in my work and in my development as a native Android and KMP + CMP developer.

The careful and methodical way, each module and component is explained, makes following the course, both productive and easy to follow.

This is a very well structured and comprehensive course. All relevant subjects from the basics to more advanced topics are covered in a logical order with worked examples. The team also respond well to any issues found.

Here's my 10 cents worth verbatim re Philipp's new "Kotlin Beyond Syntax" course, which I originally sent to Philipp/PL-Coding as a thank you :

"Hi Philipp, just wanted to say :

Am loving the course so far, is filling in a lot of tiny gaps in my knowledge here and there, helping kotlin all make more sense to me now.

Can't wait until I've completed the whole course ... am already feeling far more confident re kotlin/my knowledge about it.

I can/would thoroughly 100% hands-down recommend this course to anyone wanting a complete understanding of kotlin, and as always I am totally impressed by your professional approach to making these videos/courses. They're a very far cry from others out there : "um, ah, what I mean is, ok let me try this instead ...". You've really planned the course/thought it all through. Super professional bar none !!!!

Thank you for all your hard work and total commitment ... probably the best ~€88 I've ever spent !!!!

Thank you Philipp 👍🙏😀"

Guaranteed 5+ stars !!!!

As a Senior Android Developer, I’ve taken many courses over the years, but I still make a point of purchasing Philip’s courses whenever a new one is released — and that says a lot.

The material is always presented in a clear, structured, and highly practical way. Complex topics are explained with concrete, real-world examples, making them easy to understand and immediately applicable in daily development work. The balance between theory and hands-on demonstration is excellent.

What I particularly appreciate is how the explanations remain accessible without oversimplifying important concepts. Whether you are just starting your development journey or already an experienced professional looking to deepen your knowledge or refresh best practices, these courses consistently provide value.

I highly recommend Philip’s courses to developers at any stage of their career.

Amazing. Highly recommended. Huge amount of great value for a great price.

I've been following Philipp work for years now. He is an incredible instructor, with a variaty of courses perfect for people wanting to learn about Android, Kotlin, Compose, among others, no matter if you're a beginner or a Senior developer. Totally recommended to learn with him!

The course material is structured and Philipp is really taking care of explaining concepts in a clear and concise way.

Great course by Philipp. Clear and thorough explanations.

I bought several of his courses and also enrolled in the mentoring program. I’m very satisfied with the quality of the content and the feedback I receive. Everything is clear, practical, and well structured.

very helpful.God bless you Philip Lackner. Living legend . I found one and only man who could teach any one KMP very easy way .

A comprehensive course about architecture: covers the most recent tecnologies, with great depth in content, a great teacher, and it's a great course. Highly recommend.

Philipp is teaching me about Android Development and th future of it. The videos also cover the latest news about Android, and mentally massage us while we are bothered by how AI impact to our mobile development career

The courses are great, video shows coding and building applications from scratch to end product but with so many tips and tricks.
Watching the one of the courses, I've got feel like I am working on that code with my colleague.

This tutorial elevated my expertise in Compose, clean architecture, Flow operators, and custom components far beyond what I thought possible. Whether it was building sophisticated UI components or tackling many-to-many Room relationships, Philipp's approach pushed my technical abilities to new heights.
