Hi, I am Jonathan and I sketch, develop and publish mobile apps. A total of 6 million people downloaded my apps so far. My best selling app is a geography game called Where is that? which helps children and adults to learn about the world.
During and after my Master in Business Administration I worked in Investment Banking at Dresdner Kleinwort, Goldman Sachs and Commerzbank. Eventually I decided to turn my hobby since I was 14 into a business and quit the banking world.
I now do what I love and that's what you can do best. I have the freedom to travel the world with my wife, who is a business consultant. That's were I collect my ideas for new apps. My approach as an Indie developer is to start with a great Minimum Viable Product (MVP) and then take the successful ones to the next level.

Another very #important tweet from your twitter.
I sketch, design, develop and publish mobile apps.
I develop modern modular apps in standard Objective C with code and UI test automation and continuous integration.
I am not a designer, but I know how to craft a simple and intuitive app interface with the help of outside resources.
I optimize the presentation in the App Store with eye catching screenshots, a compelling description and optimized keywords. Try searching for geography in the Apple App Store.
I evaluate which elements of an app are used and what to focus on in further development. That's user demand driven development and the only path to success.

Feedback from my users in the App Store.
I've learned so much with this App. It never crashes and every version fixes the minor bugs. The best games are those that teach you something, and even more if they're as competitive as this one. It's important to learn geography, because there are people living in each of those places who must not be ignored.
I own hundreds of geological apps, and this is one of the BEST, might be the very BEST of all!!!! I love that this app includes the cities of various countries, in addition to just about everything I need to learn and really know the location of the countries and capitals. I love both Where is That? and What is There? Perfection!!!!
