Become an Expert for Building High-Performing Native Android Apps
Stand out from hundreds of developers who aren’t specialized well enough
The market of native Android development isn’t as crowded as web development for example which makes it the perfect niche to become an expert in.
Earn a 6-figure income from any place in this world
Android experts are rare and therefore paid well. If you learn to build solid apps, you don’t need to worry about your financial future anymore.
Acquire a future-proof skill that is in demand like never before
In a lot of scenarios, native Android apps are irreplaceable. Flutter and React Native can’t make up for that.
Learning Android Development takes too much time?
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 endless Stackoverflow posts in Google Search (and let’s be honest – if you visit page 2, you know you’re lost).
It just quickly gets way too much. Bad courses with bad explanation, deprecated YouTube tutorials from 5 years ago and Google behind your neck publishing new technologies and frameworks faster than you can look.
And in the end solving your problem just took a few minor adjustments, but you spent another whole day in frustration, you would’ve much rather spent on your hobbies or with your family. We all know time is the most precious resource we have which makes this even more frustrating to spend hours for a problem someone else solves in minutes.
And let’s be honest, I fully understand when people quit because of this. Too often I temporarily quit coding as well because I was so desperate and thought I wasn’t made for this.
I felt like there was something missing. Something I wish I would’ve had when I started. All I really needed was someone who gave me a clear structure and roadmap I can just follow along without falling in a big hole of disappointment. Having such a great structure paired with easy to understand explanations would’ve saved me months or even years in my journey.

What people are saying about Philipp’s courses
Martin Kiper convinced his interviewers thanks to Philipp’s courses
“The return of the investment is insane for the courses.”
Alon Shlider saved tons of hours with Philipp’s courses
“You can try it on your own with the Android docs, but it will take MUCH longer.”
Peter Suchanek found a job as an Android developer with the help of Philipp’s courses
“Philipp goes into a lot of depth with concepts you cannot really find online.”
Rahul Ahuja gained the knowledge needed for an Android job in another country
“What these courses gave me was a push to develop real-world applications rather than doing some proof-of-concept stuff.”
Pavel learned building apps for his clients thanks to Philipp’s courses
“If it wasn’t for him, I wouldn’t be here today.”
Simon applies concepts learned from Philipp’s courses in an app with 5M downloads
“After just 20min, Philipp was able to answer all my questions.”
Esau has the same position as developers with 2 more years of experience
“Philipp’s courses are really worth what they cost.”
Elangovan cracked a coding interview because of the knowledge learnt from Philipp’s courses
“I strongly recommend Philipp’s courses for everyone who is fascinated about Android development.”
I have already had experience in Android developement before this course but I lost a bit of track to the best practises and state of the Art. This course brought me back on track really fast and Philipp really took care to convey general knowledge that can be applied on every Android project. I can recommend this not only for experienced developers but also for beginners to learn the right practises from the very beginning.
I have been using modularization for a long time, but I learned new cool stuff and tricks in your course that will change my way of thinking about how I should design my code.
I really encourage every Android developer to take this course, it will definitely take your skills to the next level👏🏾👏🏾
Thank you Philipp, and looking forward to the next course 😍
At first I thought that changing my career will be much more difficult. I started to learn Kotlin, then I found Philipp’s YouTube channel. I had the feeling he is posting, everything I need, so I stick with this channel. And after some time, I felt like I can be something… What’s unique about Philipp, that he cares about those who are looking for help, he answers to PM’s, I’ve never had experience like that. He’s voice is easy to listen to, and from he’s listeners he made a community, with same minded people. If you learn from him you don’t only get knowledge which is worth the money, but you also get a programmer that helps you, and community which opens you a lot of chances So even if I’m not a pro, I can say I’m a part of community. Why not you be part of it ?
Hi Philipp! Just finished your multi-module course, loved it! The module configuration, the clean architecture explanation, and the way you suggest to set gradle are exactly what I was searching for. Infact i’ve already implemented a module for a complex multi-permission handling that I’m sharing between all my apps! Ad-hoc versioning and concepts separation are saving me a lot of time. Your course let me also the opportunity to enhance my jetpack compose and unit test skills . So, I can consider me super satisfied. Please, don’t stop mentoring 💪
Taking any of Philipp’s courses makes you go from 0 to almost 100 in understanding the concepts in no time. He explains the basics so well and teaches real world application use cases which will enable you to not only up skill your self but to increase your confidence in Android all together.
This course is definitely a must buy. Philipp teaches you the most important aspects of working in the Android development industry, with up to date best practices and great code scalability. I’ve had struggles working with big projects, but after this course I feel so much more confident in my skills in building large robust apps.
