My Best Apps of 2014

In the end of the year, I would like to share some of my data and assign “Best Apps” in Geography and Chemistry categories.

I will remember 2014 as the Year of Quizzes. Since Hydrocarbons appeared on iOS on January 31, I have released more than 40 distinct quizzes. In September, most of them were published on the Google Play Store as well. And these quizzes were much more successful than my first apps released last year. So far I have 578k downloads for iOS and 215k downloads for Android. Total earnings are well higher $20k.

Geography

The most profitable iOS app: 50 US States – $4k

“Download

The most downloaded iOS app: European Countries – 55k

The most profitable Google Play app: Swiss Cantons – $650

Chemistry

The most profitable and most downloaded iOS app: Inorganic Acids – $800 and 31k downloads

The most profitable Google Play app: Chemical Substances – $66

The most downloaded Google Play app: Functional Groups – 14k

So it’s clear that Geography is more popular than Chemistry and it’s likely that I’ll continue moving in this direction. A funny fact for me is that the most promising app of recent months Flags of the World hasn’t won in any of 4 categories. Let’s see how it will change in 2015!

Financial Report – September 2014

All important apps have been rewritten for Android and now I have 46 apps on the Apple App Store (iOS) and 38 apps on the Google Play Store (Android).

Here is my income from Jan 2014 (about $15.5k so far):

In January, I was earning on average $3.5 a day. Since August 20, my daily income haven’t fell below $150 / day. Total income in August is $4,198. This amount is comparable with my salary that I had 2 years ago as a chemistry postdoc at Berkeley.

75% of money are from showing ads and only 25% from sales and in-app-purchases (next week, all my apps can be downloaded for free).

The most profitable are Geography apps, such as:

50 US States (iOS, Android) $2,532 (16.5% of total income).
European Countries (iOS, Android) $2,098 (13.6%).
Flags of the World (iOS, Android) $1,448 (9.5%).

Localization into 9 languages was a very clever decision. United States accounts for 28.4% of total income, Germany 10.9%, Russia 8.8%, France 6.7%, and so on.

The Google Play store is very different from the Apple App store in download trends, search optimization and algorithms. By now, the income from Android apps is just $15.29 but it is constantly growing and I’m just in the beginning of understanding this platform.

Many thanks to everyone who supports me. I will be glad to answer your questions and hear your suggestions how to improve my apps.
