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
The most downloaded iOS app: European Countries – 55k
The most profitable Google Play app: Swiss Cantons – $650
The most downloaded Google Play app: Capitals of the World – 38k
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!

This makes me wish I had studied Chemistry or even Bio-Medical Sciences. Anyway, my best wishes for 2015!
Thanks! I love Chemistry but sometimes I think I’d have better studied Computer Science.
I Want More Languages And Flags Like Western Sahara Abkhazia Etc. And New Languages Like Arabic Hindi Thai Etc.
Thank you for your feedback! I added the Arabic language in the recent update of the Flags app on Android.
interactions beyond solo gameplay.Educational Battles for Flags and Capitals:Another exciting addition could be educational battles focused on flags and capitals. This feature could provide an entertaining way for players to learn about different countries, their flags, and capitals. It could be implemented as a quiz-style competition during battles, making the gaming experience not only enjoyable but also educational.I believe these additions would not only enhance the overall gaming experience but also contribute to the educational aspect of the game. Thank you for considering these suggestions, and I look forward to seeing the continuous improvement of your game.
