Hello everyone, my name is Jens and I am currently doing my PhD in the field of digital health care. In the context of mobile crowdsensing, I am currently developing a library that will enable scientific studies to monitor sensor data from subjects' devices. For Android devices I have already implemented a so-called ForegroundService, which runs while the app is closed and also restarts itself after a reboot. For iOS, however, I have not found a way to implement the same. Is there a way to implement such a library? And if so, with what limitations?
