I understand this is completely off subject, but then again not as much. As part of my life experience I would like to be able to create my own widgets to display particular information or allow particular input. Is there any such FOSS app similar to KWGT Kustom Widget available? I have very limited past knowledge in coding, but I am willing to go through the learning curve of learning to code and compiling my own app. I would be very grateful if you could point me in the right direction in terms of educating myself in order to fullfil my goal. I don't have a desktop, so can't use Android Studio. Can I code vs check result on my own device and if not, what is the most convenient way to achieve it?
