Android Income Report #14: June 12

June is over and I’m far earlier with this report than with the last one, here it goes:

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 $2,000 for the last month. You will see if it worked out.

Which Apps?

3D Invaders – about 267,000 installs (+11k), 14% active

AL Voice Recorder – about 815,000 installs (+34k), 19% active

AL Voice Recorder Ad Free – 1,133 installs (+45), 33% active

Droid-Blog.net Android App – 530 installs (+19), 13% active

SmsToSpeech full – 778 installs (+11), 26% active

45,000 new downloads, that’s a not a good result.

What did I do?

Nothing big, a few bug fixes.

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: 533,586 (-52k)

Impressions: 530,543 (-49k)

Fill Rate: 99.43% (+0.51%)

Clicks: 19,134 (-3.9k)

CTR: 3.61% (-0.37%)

eCPM: $1.97 (+$0.45)

House Ads: 4,538(+3,261)

Adjusted Requests:  538,124 (-49k)

Adjusted Fill Rate: 98.59% (-0.11%)


Requests: 731,824 (-399k)

Impressions: 39,698 (-7k)

Fill Rate: 5.42% (+1.3%)

Clicks: 1,698 (+256)

CTR: 4.28% (+1.19%)

eCPM: $3.37 (+$0.14)

Interestingly a way bigger loss in requests and impressions on the madvertise side than on AdMob’s. Still, their results got a little better, maybe there’s even more room for improvement in the next months.

How much?

Here are the numbers:


3D Invaders: $295.55

AL Voice Recorder: $750.54

AdMob Total: $1,046.09 (+$166.26)



3D Invaders: ~$57.25

Market sales: ~$114.46 (+$13.60)

In-App purchases: ~$12.39 (+$0.83)

Total: ~$1,306.82 (+$163.66)

A little increase but not $2000.


What’s next?

I didn’t reach my last month’s goal, so, again, it will be $2,000 for the month of July.

Android Money – Income Report #2: June 11

June is over, so it’s time for my monthly money report 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 Android apps too. In the last report I aimed to reach $750 for the last month. You will see if it worked out.

For all money reports, please click here.

Which Apps?

You might have noticed that Droid-Blog.net now has its own Android app. The number of ad requests and downloads was enormous and so was its overall success. Here are the numbers:

3D Invaders – about 82,000 installs (+10k), 20% active

AL Voice Recorder – about 335,000 installs (+15k), 26% active

AL Voice Recorder Ad Free – about 650 installs (+-0), 44% active

Droid-Bog.net Android App – 10 installs (+10), 30% active

SmsToSpeech full – about 640 installs (+40), 44% active

What did I do?

As you can see the AL Voice Recorder gained 15,000 new users while the overall userbase declined a bit (about 3,500 active installs were lost). 3D Invaders had some frequent updates and new weapons in the first half of the month. Some days later I also published In-App Billing. While the latter was not quite successful, the overall active downloads increased while the download-active installs-ratio stayed the same. Also, I switched back from Mobclix to AdMob which resulted in an increase in AdMob income.

The Droid-Blog.net app was able to get a total of fantastic ten downloads and brought in not a single cent. AL Voice Recorder Ad Free didn’t sell many copies too, but somehow SmsToSpeech Full was sold about 40 times. I didn’t do any further investigation why this happened, but I positively accept it.

Advertising Stats

Sebastian S. suggested to include not only download numbers, but also ad statistics. Before I start some definitions:

A request happens when a device requests an ad to be served. An impression is an ad that is actually delivered and shown on the device. The fillrate is the impression-request-ratio (#impressions / #requests * 100%). The CTR (Click Through Rate) is the clicked ads-impressions-ratio (#of clicked ads / impressions * 100%). The eCPM is the average money generated by 1,000 impressions or, in other words, the value of 1,000 impressions.

I also use the term adjusted fillrate and adjusted requests . These numbers are the same as described above, but they are taking house ads into account. House ads are ads published by you in your own products. They are free of cost and are not part of the request and fillrate numbers. My settings are made in a way that house ads are only delivered if no payed ad can be displayed which is why I’m introducing these adjusted numbers here (as otherwise the transferet impression could be missleading).

Here is how the two main ad networks I used last month performed:


Requests: 460,532

Impressions: 455,912

Fillrate: 99.00%

Clicks: 8,419

CTR: 1.85%

eCPM: $0.81

House Ads: 23.,739

Adjusted Requests:  484,271

Adjusted Fillrate: 94.14%


Madvertise doesn’t offer house ads, so the adjusted numbers are equal to the normal numbers here, therefore they are not mentioned. Edit, I received an e-mail from Madvertise: Madvertise does offer house ads, but you have to mail the support for that. In the future, it will be automatically available for everyone.

Requests: 335,352,

Impressions: 55,401

Fillrate: 17%

Clicks: 2,622

CTR: 4.73%

eCPM: $5.44

The bad fillrate of Madvertise is because it is focused mainly on european countries. While the most clicks come from the UK, German clicks are by far the most expensive. They grossed an eCPM of $12.77 in the last month, so if your app targets Germany, go and use Madvertise! By the way, the customer service is also great, while it is almost not existent at AdMob.

The CTR is also way higher on Madvertise, but it seems as if this would change in this month (AdMob is becoming better).

Ok, how much?

Here is how much I earned:

AdMob: $367.96 (+$107.45)

Madvertise: ~ $302.16 (+$7.16)

Market sales: ~$74.41 (+$29.41)

Mobclix: ~$0.32 (-$50.62)

Total: ~ $744.85 (+93.38)

As you can see I disabled Mobclix very early in the last month. I didn’t reach my goal of $750, but I got very close to it. To me, it’s still satisfying.

What’s next?

This month I will have lots of work to do, so I will be able to work on my own apps only in the last third. I will focus on an new fantastic app (you will love it, I hope) and the AL Voice Recorder this time. Because I have not that much time to spend, my goal for the next month will be $800.-
