It depends on how you measure success and the benchmark you are using.
If I compare the app with many similar apps from Nigeria, it is a success but when I know that some apps are getting 10 million downloads in 2 years then I might not consider 800,000 in 2 years a success.
In total, all my apps have around 2.2 million downloads
The good thing is that I make good money from it despite the fact that I have not updated them for 6 months or more.
WHY I DON’T WANT TO FOCUS ONLY ON ANDROID APP BUSINESS
The pattern I have seen in Google Play and with my little experience, I have ideas that can get millions of download within a year now but I don’t want to execute them now.
BECAUSE I CAN"T PREDICT GOOGLE
1 Google Account Ban
It is hard to follow all their TOS (Terms of Service) changes and it usually end up in ban account. Your business and money will die with it.
2 Low Ad eCPM
I make money through Google Ad but right now the eCPM keeps going down. For example, you can make 3000$ in a month last year and by this year with higher download numbers and active users you will be making 1500$
Personal Preference
Because I have a family I want to make sure that I can make a plan every month and pay my bills not hoping on what GOOGLE decides.
New experiment I did about alternative income online vs Android App revenue
I have a domain I bought 2014 but I could not find any more use for it. I decided to use it for experiment.
I created a blog for android tutorials. Around middle of last year I became serious with it.
The blog has been growing and the result after a year and is surprising.
I am getting lots of freelance android, iOS, Java and Php projects right now and I make more money monthly in dollars than Android App reveune.
This has been wonderful sources of alternative incomes.
