This is a basic strobe light that flashes on and off. This strobe light is very basic so don’t expect much from it and don’t leave a 1 star rating. It is supposed to be a basic app that you can just turn on and use in a time of need. The screen flashes on and off fast or slow depending upon your choice at the main menu. Also we may be adding other features and colors if people like what we have done so far.. I hope you enjoy this basic strobe light.Note: Does not work with camera flashThere is a version is Ad-Free. If you don’t want to pay a dollar, please go and download the Ad version called Strobe Light.Enjoy!!!
