Income Report #17: Sept 12 – Aug 13

If you are new to this series, let me explain it to you: Since Android is an open platform, I decided to be open about the income I’m making with my private Android apps too.

The last income report lies back almost a year. We’ve had a big job at ANDLABS which consumed almost all my time and also stopped me from working on my apps and also reduced my post frequency. Since this job is done now, there will be more reports and even a newsletter.

For now, here’s a summary of the income my Android apps generated in the last year.


Which Apps?

3D Invaders – about 350,000 installs,

AL Voice Recorder – about 1,027,000 installs,

AL Voice Recorder Ad Free – 1,117 installs,

SmsToSpeech full – 750 installs,

The careful reader might recognize that SmsToSpeech full and AL Voice Recorder Ad Free have a decline in installs, which should technically not be possible. I ascribe this to a different way of counting Google is using.


Advertising Stats

Please read the second income report for an explanation of the following numbers.

Here are some statistics of the Ad frameworks I’m using. Unfortunately there seem to be issues with madvertise’s reporting system, which is why I’m only showing AdMob numbers here. To summarize madvertise’s performance in the last year though: It was underwhelming.


Requests: 2,732,264

Impressions: 2,700,974

Fill Rate: 98.94%

Clicks: 95,954

CTR: 3.55%

eCPM: $1.70

House Ads: 104,351

Here’s the distribution over the months:

AdMob Income

AdMob Income Sept 12 – Aug 13


How much?

Here are the numbers:


3D Invaders: $1,596.55

AL Voice Recorder: $3,010,52

AdMob Total: $4,607.19

Market sales: ~$407.55

In-App purchases: ~$41.25

Distributed Google Play Sales, including In App Purchases

Distributed Google Play Sales, including In App Purchases

Total: ~$5,056.35

It’s obvious that my app’s performance was not good compared to the months before, where I put a little more emphasis on maintaining their market position. Still, $200-$300 extra on the bank account every month don’t hurt.


What’s next?

For now I will focus on the development of a new game. Hence I don’t expect my income to rise until it’s published.


Please feel free to share your own experiences and hints in the comments. Ask questions, share, do whatever you like.

  4. Hello Johannes,

    do you still use Madvertise? I got no payment since some month and want to know, if i am the only one.

    • Hi Horst,

      I’m still using it but unfortunately the fillrate is way too low to get any payment for me.
      It’s really not satisfying.

      Best regards

  5. Good to see you are making some money with admob.
