GlowClock's fullscreen clock is used across hundreds of different contexts. Teachers project it during exams and timed activities. Gym coaches use it for interval training. Remote workers keep it on a second monitor as a permanent desk clock. Streamers display it on screen during live sessions. Parents put it on a tablet in children's rooms as a bedside clock.
The common thread is simplicity: a single large display showing the time, with nothing else competing for attention. The fullscreen clock mode removes every browser element — address bar, tabs, bookmarks — leaving only the time on a richly coloured background.
Each theme uses carefully balanced colours that are bright enough to read from a distance but not so intense that they cause eye strain during extended display. The darker backgrounds are particularly suited to low-light environments like bedrooms and home theatres.
