Multi Settings Shortcuts application

Hi everyone!

I published my new (and first) android application, and I would like you to give me feedbacks about the design.
The application helps especially for someone who uses a bluetooth speaker in his car (but it is helpful for everyone). and it will have more features at the future...

here is the link:
