I have a very simple goal - I create apps that do only one single task, but they do it well. Thus, the apps are extremely fast and lightweight, they do not need nasty permissions and they delight the user with a simple, clean interface. All my apps support the great Material Design. I study Computer Science in Germany. Developing Android apps since 2011, my apps on Google Play have around 1,000,000 downloads.
To keep the apps useful, it is important to listen to user feedback. Therefore, I take the time and respond to every email from the users of my apps. I fix bugs withing hours after receiving the report and I consider implementing all the features you suggest me. Just contact me and I will do my best to assist you.
