Please keep in mind, that I am a single student in my first university semester doing this project in my free time.
I try to allocate as much time as possible to version 4.0 (which will bring a completely redesigned app with many more features and many bug fixes). I hope to release it in March after my university exams.
I am currently not able to handle the immense amount of feedback I receive whilst preparing for exams. After the 6th of March I will work on responding to every inquiry. In the meantime use the FAQ or links above for help.
