Android Income Report #4: August 11

Another month is over, it’s time for income facts again.

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. In the last report I aimed to reach $1,005.02 for the last month. You will see if it worked out.

Which Apps?

3D Invaders – about 100.000 installs (+8k), 16% active

AL Voice Recorder – about 382.000 installs (+23k), 24% active

AL Voice Recorder Ad Free – 721 installs (+31), 41% active Android App – 186 installs (+66), 30% active

SmsToSpeech full – 675 installs (+19), 42% active

What did I do?

Essentially nothing. I neither published a big update nor a new app. Still, more than 30.000 new users downloaded my apps.

The app had a huge increase in download numbers again (55%)! Furthermore, after being in the Market for more than two months, it finally got its first click grossing a total of $0.03. Hurray!

Advertising Stats

Here are some statistics from the two advertising networks I’m using, AdMob and Madvertise. Please read the second income report for an explanation of the following numbers.


Requests: 438,914 (+23k)

Impressions: 420,452 (+12k)

Fill Rate: 95.79 (-2.48%)

Clicks: 8,399 (-2.79k)

CTR: 2.00% (-0.74%)

eCPM: $0,91 (-$0.17)

House Ads: 22,309 (+16.8k)

Adjusted Requests:  461,223 (+40,5k)

Adjusted Fill Rate: 91.16 96.98% (-5,82%)


As I’m not using house ads in Madvertise, no adjusted requests and fill rates are shown here.

Requests: 250,609, (-91k)

Impressions: 53,472 (-12k)

Fill Rate: 21% (+2%)

Clicks: 2,874(-440)

CTR: 5.37% (+0,3%)

eCPM: $10,28 (+$3,76)

My AdMob performance regarding impressions and request was not bad, but the fillrate and the eCPM was. While Madvertise lost about 91,000 request compared to the previous month, it was able to compensate this by having an enormous eCPM.

How much?

Did I manage to reach my goal again? Here’s what I earned:

Madvertise: ~$550.35 (+$124.28)

AdMob: $380.68 (-$58.88)

Market sales: ~$89.31 (-$41.45)

In-App purchases: ~$8.23 (-$0.40)

Total: ~$1028.57 (+23,55)

Goal reached! Why? I would say mainly because of the weak dollar. While one Euro was worth 1.4 dollars one month ago it is now worth $1.44. This made the small difference between success and failure.

What’s next?

I’m curious if Madvertise will be able to keep up those great numbers. I will be pushing some updates this month, so I hope the download figures will increase to about 33k again. My goal for the next month is $1,100.


Please feel free to share your own experiences in the comments. Please also don’t hesitate to tell me if there is anything else you’d like to get some information about.


  1. Thumbs up, Johannes! Again, congrats from madvertise!

  2. Those are great numbers. And I thought I was doing pretty well when my CTR started climbing towards 1% :) I think you should write an article on how / where to place ads, refresh frequency, stuff like that. Clearly, you’re doing something right.

    In Bus Jumper I’m running ads all the time, and I’ve often wondered if I’m saturating the viewers, who just tune the ads out. I think I saw the CTR go up when I reduced the refresh frequency, maybe it needs to be reduced some more. I tried to set it so the median gameplay session length (as reported by Flurry) would see 2-3 ads cycle. I have no idea if that’s a good way to approach this though.

    Congratulations on a good month, and thanks for continuing to publish your numbers.

  3. Johannes, you really gave me a lot of inspiration and motivation. I enjoy reading your income report. Please keep it going.

  4. I too would like to see an article on ad tips Johannes. The ads in my apps don’t do near as well as yours.
