As an early project in learning Android development, I decided to make a simple strobe light app for a friend. I decided to open-source it on GitHub in order to help any other developers wanting to learn (https://github.com/texasfight/MaterialStrobe). It contains no ads and is simple, with intuitive design and little to no clutter. Simply click the button to stop or start the strobe and adjust the slider to change the amount of "light-on-time". It will always be ad-free and low on permissions. Thanks for checking it my Material Strobe Light!
