The idea is simple, you offer mobile application development, marketing, testing and reviewing services.
I have launched such a project and you can find it here – https://www.appopsy.com/
We offer the following:
1. Development of mobile applications, preferably small quality games;
2. We offer marketing services for new and existing mobile applications;
3. You can get your mobile application tested for bugs and exploits, this is important before you do the big launch for your mobile app;
4. We also offer mobile application review services, free for now!
We are also launching our very own mobile game application very soon, you can find more about it on the main website. If you scroll to the bottom of it, you will see that we are also connected to a wide range of social media channels.
I think this will be a lucrative business because mobile applications is till a hot topic today.
