About Keep Screen On
We build simple, fast, privacy-first web utilities that eliminate everyday device frustrations.
Why We Built Keep Screen On
A modern, no-install approach to screen wake locks
Almost every phone, tablet, and laptop is configured to automatically dim and lock its screen after a brief idle timeout. While this preserves battery under normal circumstances, it often causes immense frustration when:
- Following cooking recipes with messy hands
- Delivering live presentations or webinars
- Reading long-form documentation or books
- Monitoring long downloads or render processes
- Viewing real-time analytics & trading dashboards
- Working on locked-down corporate laptops without admin rights
Traditionally, users had to dive into confusing operating system settings, install suspicious third-party utilities, or use hardware jiggler dongles. We created Keep Screen On to offer a lightweight, instant alternative: open a browser tab, click one button, and keep your display awake for exactly as long as you need.
Our Core Principles
Zero Installation
No apps, downloads, browser extensions, or administrative permissions needed. Works in modern browsers instantly.
Privacy First
Wake lock requests run locally on your device. We do not require accounts, logins, or invasive tracking.
Cross-Platform
Engineered for Windows, macOS, Linux, Android, iOS Safari 16.4+, and iPadOS with intelligent fallback handling.
Under the Hood: The W3C Screen Wake Lock API
Keep Screen On utilizes the standard navigator.wakeLock interface supported by modern browsers. When you click activate, your browser requests a system-level Sentinel that instructs your OS kernel to prevent display sleep.
The moment you toggle the button off, close the tab, or navigate away, the lock is immediately and cleanly released, allowing your device to return to normal power management.
