Why Most People Will Never Truly Make it as Developers

On the surface, app development is simple. Everything you need seems to be available online for free. However, if we’re honest, this is not as much of a blessing as it sounds like. It leads to most developers losing themselves in details that absolutely don’t matter for the industry.
Meanwhile, they completely oversee that it all starts with the essentials. It starts with the architectural and technical foundation every software needs. You can’t learn these essentials by reading a few docs. These can be only learnt by implementing them in real apps. If you don’t master these essentials in the first place, you completely lack the foundation for anything you’ll face in the industry.

Developers from these companies are learning with Philipp’s Courses…






This is Runique – The App You Will Build in This Course

1. Build an Industry-Level Running Tracker App

  • Learn to track runs in real time, and track meaningful health data from your users
  • Sync runs with the cloud by connecting the app to a remote backend
  • Implement an analytics dashboard to let users analyze their past runs
  • Learn to work with the Google Maps SDK to track and display the user’s location in real time

2. Implement a Complete authentication system

  • Get exclusive access for a remote API to let users create accounts and log in
  • You will learn the ins and outs of OAuth and implement proper session management
  • You’ll learn all the relevant architectural practices that help you to implement such features into a scalable project

3. Connect to a smart watch

  • You will learn to build a Wear OS app in order to track more vital health data such as the user’s heart rate
  • Learn to discover paired devices and connect to the right one
  • Implement watch to phone communication and what it takes to correctly sync exercise data
  • Get to know the health services API to implement proper exercise tracking

Most devs think they should focus on …

  • what is the best library for implemented a specific feature in their app.
  • blindly learning every new technology in the moment it reaches the alpha state
  • learning the typical “best practices” having no clue why and if they’re actually helpful
  • strictly sticking to specific architectural rules, like clean architecutre (without even understanding why)

While you should focus on …

  • proper planning and structuring apps so that they scale and are easy to be worked on in a team
  • the essential technologies that EVERY app is built on top of
  • the fundamental architectural principles without becoming religious about a specific paradigm (e.g. Clean Architecture)
  • truly understanding these essentials in-depth, since the rest will come by itself

With over 10,000 sold copies of his courses and 700h+ spent for teaching Android concepts, he already helped thousands of 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 mobile developers what really counts for becoming an outstanding developer.

Project Planning

How do you even start a project without having a clear structure?
This course will teach you how to come up with a starting structure that is set up to scale based on your app’s requirements.

Multi-Module Architecture

You will learn the ins and outs of a multi-modular Android codebase. Specifically, that means:

  • The foundation of every good architecture
  • Why and when to pick a multi-module architecture?
  • Which modularization strategy is the best?

Gradle for Large Scale Projects

The more your project grows, the more managing its builds becomes a mess.
In this course, you will learn proven strategies that allow you to tame Gradle and…

  • … have light speed builds

What People Say About Philipp’s Courses

Martin Kiper convinced his interviewers thanks to Philipp’s courses.

“The return of the investment is insane for the courses.”

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.”

Alon Shlider saved countless hours thanks to Philipp’s courses

“You can try it on your own with the Android docs, but it will take MUCH longer.”

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.”

“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.”

Luka Lukovic

“I have already had experience in Android development 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.”

Matthias Kerat

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 ?

Ozzy

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.

FAQ

What are the prerequisites to take this course?

You should be familiar with basic Android development. That means you should be familiar with Kotlin and know core concepts of Android (Activities, Jetpack Compose UI, Intents, etc.).
Other than that, the course teaches you all the essentials.

Can you follow through the Wear OS course without the main course?

You can, but it’s strongly recommended to get it together with the main course. If all you care about is Wear OS development, the Wear OS course will be enough for that, but be aware that it will be built on top of the main course.
In particular, that means that some pieces of code from the main course will be reused in the Wear OS course.

I watched "Building Industry-Level apps With Multi-Module Architecture". Is this course still for me?

Absolutely! Multi-module architecture is just one concept taught in this course together with many others Philipp never taught before.

What if the backend access expires?

Together with these courses, you get 6 months of API access as a bonus for free. After your API access expires, you’ll still be able to follow through the course, since in the course you’ll also learn how you can run this backend locally on your machine.

What if I don't like the courses?

Just as for all of our courses, you get a voluntary 30-day money back guarantee in case you’re not satisfied with the course content.

Do I get lifetime access?

Yes, it’s a one-time investment into your career to keep access to the course and updates in future.

Will I get a certificate on completion?

Yes, after following through the course, you can take a final quiz that covers the concepts taught in the course. If you pass it, you will be awarded a certificate you can use to show off that you have the essential skills of software development.
