February is over, time to sum things up.

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 $4,000 for the last month. You will see if it worked out.

Which Apps?

3D Invaders – about 212,000 installs (+20k), 16% active

AL Voice Recorder – about 652,000 installs (+60k), 21% active

AL Voice Recorder Ad Free – 961 installs (+51), 36% active

Droid-Blog.net Android App – 431 installs (+27), 14% active

SmsToSpeech full – 740 installs (+14), 32% active

80 thousand new downloads, with the voice recorder speeding up a little while 3D Invaders gained about 2k less downloads than in January, but we have to keep in mind that February had two days less.

What did I do?

Lots of work, especially for customers, no updates for my existing apps.

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.

AdMob:

Requests: 692,041 (-16k)

Impressions: 680,731 (-14k)

Fill Rate: 98.37% (+0.25%)

Clicks: 20,207 (+2.2k)

CTR: 2.97% (+0.38%)

eCPM: $1.29 (-$0.02)

House Ads: 2.496 (+1,559)

Adjusted Requests:  694,537 (-14k)

Adjusted Fill Rate: 98.01% (+0.03%)

Madvertise

Requests: 1,181,607 (-22k)

Impressions: 143,392 (-17k)

Fill Rate: 12.14% (-1.18%)

Clicks: 4736 (-1,775)

CTR: 3.30% (-0.76%)

eCPM: $5.24 (-$1.25)

While AdMob stayed at about the same level like in the last month, madvertise lost another percent in its fillrate again. To make things worse: Also the CTR suffered, reaching almost an AdMob level. To give a little preview: Many of you may know that madvertise’s developer fund ended with the beginning of this month. Since then, the average fillrate went down to 6% which is really painful. I hope this will change soon or I might have to change my ad networks once again.

How much?

Here are the numbers:

madvertise:

3D Invaders: ~$597.49

AL Voice Recorder: ~$153.72

madvertise Total: ~$751.21 (-$288.93)

 

AdMob:

3D Invaders: $269.61

AL Voice Recorder: $609.21

AdMob Total: $878.82 (-$28.27)

 

Market sales: ~$76.63 (-$58.19)

In-App purchases: ~$14.83 (+$2.65)

 

Total: ~$1,721.49 (-$372.74)

It is clearly visible that madvertise doesn’t perform as well as they did in the end of 2011. Since the developer fund ended and the fillrate dropped even more, I assume that the madvertise results in March will be way less than now, while AdMob will probably bring one or two more dollars than in this month.

What’s next?

I didn’t reach the goal I set in the last month, so it’s $4,000 for this month again. I think this almost is impossible since I will be travelling a lot this month and, as I mentioned, the madvertise developer fund has ended.
