Timerhooker (Modern Glass UI)

Instantly switch all site timers and HTML5 video speed between normal and 16x speed with just one tap on the floating button.

Disclaimer: This tool was built with Perplexity AI assistance. Use it freely or skip if not needed.

Works everywhere: Compatible with all websites and devices, with automatic light/dark mode adaptation.
Draggable floating button: Always visible, draggable anywhere on the screen, and position saved across sessions.
One-tap toggle: Switches all timers and videos from normal (1x) speed to fast (16x) instantly, with visible play/stop icons.
Auto half-hide: After 3 seconds of UI inactivity, the button slides halfway off the nearest screen edge but remains clickable.
Privacy and stealth: Blocks most attempts by sites to detect page visibility or focus changes, preserving your privacy and functionality.
Safe & local: Runs fully locally without sending any data externally. Uses localStorage only for UI position persistence.
Optional keyboard accessibility: The script includes commented-out code to enable toggling via keyboard (space or enter keys) when the button is focused, enhancing accessibility for keyboard users.
