We will compare the results for four weeks, aligned by the week day, using the data from February/March for Admob, and April/May for Mobclix.

This is the revenue that we generated per day (*):

And here, the revenue per click, which is our preferred indicator to compare how different ad providers perform:

All this has been generated by three applications, that currently have 100k active users (after over 200k downloads). It is difficult to keep track of how many users we had in each ad provider at every point in time, so comparing absolute numbers, like we did in the first graph, does not yield relevant conclusions.

In an upcoming article, we’ll show values that analyze the long term figures!

(*): We have multiplied all figures by a factor k € [0.2, 5.0], in order not to disclose our real numbers while providing meaningful data. This correction is consistent, i.e. if you have 2x active users, expect a similar price per click but double the revenue per day.

We would like to share the time spent in the development of some android applications., in the last months we have had development sprints releasing two games, one app, a chrome extension and some huge improvements in our already released apps. Once you have some experience with Android it is not very difficult to start a project from scratch.

We developed Poke the droid, a simple game similar to Whac-a-mole that test your reaction times. The main motivation was to develop our first game, assuming it will not get the success of other popular games out there. It was developed from scratch in around 2 weeks.

Recently we released Super Stacker, the popular stacker game with some improvements like bonus, levels, etc. We began with Snake demo code as the base so it was not really difficult to be developed (one week), moreover we reused almost all the score system and UI from Poke the droid.

Another simple app we created is Spell Checker, this is a extremely simple application that check your words against Google system. We test the integration in a WebView of a remote web page with the Android system. It was a day of development, thanks to the Javascript library of GoogieSpell.

On the other hand, we have made a huge refactoring in our RSS reader Any RSS reader + widget (1.99 EUR). We have add the feature to open as an application, so you can access your saved feeds from the widget and from the app. It is #11 in the Top Paid of the News and Weather category, this fact has multiplied x2 the number of purchases per day.

Finally, one of us in a boring day developed a simple extension for Chrome called Android Market Link Converter, that converts links like market://search?q=pname:com.androidsx.anyrss into links to the most known Android Market clients (Cyrket, Bubiloop, etc.).

Now, we would like to make use of the Android Cloud to Device Messaging Framework, but at the moment we don’t really have any interesting idea

Do you have some fast development experiences? Share with us!

The revenue per day was very unstable. In the last weeks, it went sharply down with no apparently reason (almost 30%-40%). We tried hard to understand how the Admob network works internally, with no happy end. We have more users, more impressions, more CTR but much less revenue… (stay tuned for an upcoming post where we share our stats).

After some twitter posts trying to find fellow developers with whom to share experiences, we were contacted by a Mobclix employee suggesting we switched to their mashup of agregated advertisement networks.

So, we tested Mobclix with the smallest app (in active users) with ads that we have, the MLIA widget:

Here it is the comparison between Admob vs Mobclix in MLIA over the same days, it looks really promising!

Admob stats

Moblix stats

Still, it is very soon to draw firm conclusions. This is the start of a series of post with the comparative.

• According to our Flurry stats, the best day to update an application is Friday morning (European afternoon or evening). On other days, such as Wednesday or Thursday, you usually get more downloads. However, other developers don’t usually release new versions in the weekends, so your application stays longer in the top of the Just in section.

• At the moment, Android users are not accostumed to paying for an application. So, if you want to make money with your application, which strategy should you follow? Free and paid version? Free with ads? Our experience with a paid version is not quite as motivating as we expected (just a few hundreds Euros since September). Free applications with ads have more users but usually less money. The decision depends on many factors, and there’s no magical answer. We’ll probably do an experiment with our paid application, making it free application and adding some AdMob ads (Google Adsense is only available for apps with 100K daily pageviews).
• It is important to have good ratings during the first days as a new application in te market. Bad comments and ratings in the first days will make it difficult to start growing and get enough relevance to appear on relatively top places in the search results. Make sure your application is pleasant to use from the beginning: focus on reliability and stability rather than on advanced features. You do not want to annoy your first users.
• Add as many relevant keywords in the description that identify your application as needed: it is too optimistic to expect people to search specifically for your application name.
• Most of the users don’t care about the impact of a bad rating. If there’s any small problem, they will just throw in a bad rating/comment and uninstall the app. On the other hand, we must take care of the lovely users that suggest new features, report bugs, etc..
• Be careful with your update frequency: it is annoying for users if you update too frequently. In the Android market, each update goes to the Just in section, which has been really controversial in the Android world. There are many developers that abuse this by making frequent updates to get more downloads. On the other hand, getting visibility on the market through the search or the rankings is not easy, so updating is one of the best ways to gain more downloads: but with real updates, don’t be evil!.

In other posts, we will talk about the limitations of the Android market. If we are to compete with the App Store, the market should be one of the main worries for Android Core Developers and learn from its competitors. Yes, the UI is better and what not, but the visibility, the search and the average money (check this study) that you get with your applications is much lower than in the App Store. With tech companies such as Motorola investing a lot of resources in Android, there will be really powerful market competitors such as SHOP4APPS (seen in El Androide libre, in Spanish).
