Why do our courses have fewer students than most courses on Udemy - because we do NOT try to mislead our new students.

  • 100% real and paid students - We do not believe in the practice used by many instructor on Udemy that offer their courses on blackheads sites to inflate their numbers, our students are real, they participate on the course, help each other other .
  • 100% real reviews - We have never bought any review from other sites like fiverr or similar, which is another very common technique among instructors on Udemy.

What to look for when buying a course on Udemy:

  • Look for the questions on the course during the free preview, the time it took for it to receive an answer, the quality of the answer, how happy the student was with the answer.
  • Look for the instructor profile on LinkedIn, and other places.

Take a tour in the course. Get to know your future instructor before making a decision. After all, it's your future on the line!

I am sure you will make the right choice so I will see you inside!

As applications get more and more complex, clients demand faster interaction. They want to receive a post, a notice, an event as soon as it happens. They want to know if a friend is online or offline in a chat application as soon as the other party changes their status. They want to know these things as soon as they happen, in other words, in Real-Time.

Implementing real time systems can be very costly, complicated, and time consuming. This is where Firebase comes into play to save the day.

Firebase starts with a FREE tier that can be used even in your commercial applications. It also comes with a very simple to use API that can be use for iOS (including Swift), Android, and JavaScript so you don't have to worry about compatibility.
