Prevent your computer screen from locking with Mouse Jiggler. Compatible with Windows and macOS computers, this application prevents your computer screen from locking by periodically moving your mouse cursor a few millimeters. MAIN FEATURES : - Scrolling Mode : Scrolls an image and increases screen brightness at regular intervals to move your mouse cursor. - Vibration Mode : Vibrates your phone at regular intervals to move your mouse cursor. (Vibration mode is not available on iPad) - Power-saving Mode : Activates intermittently to consume less energy. - Undetectable Mode : Use a random time interval between two animations to be practically undetectable by most monitoring systems. - Completely Free App ADVANCED SETTINGS : - Vibration : Enable or disable vibration mode. - Vibration Duration : Customize how long each vibration lasts. - Pause Duration : Set the time between two scrolls or vibrations. - Brightness Level : Adjust the brightness level when the app activates. (Reducing it too much may impact effectiveness.) COMPATIBILITY : Mouse Jiggler is officially compatible only with mice that use a visible red light (optical sensor). Mice that use invisible light, such as infrared or laser sensors, are not supported — even if they might occasionally work. This is not a bug, but a limitation related to the sensitivity of the mouse sensor, as well as your phone’s maximum screen brightness and vibration power. If you experience issues, we recommend using a mouse with a visible red optical sensor. WHY CHOOSE MOUSE JIGGLER ? - No Extra Hardware: Unlike USB dongles or jiggling pads, the app only needs your phone and your mouse. - More Private: Unlike desktop software, this mobile app leaves no digital trace on your computer. - Free & Convenient: A simple, cost-effective solution — similar hardware tools can cost up to $30. DISCLAIMER : Do not use this app if it conflicts with your employer's policies. Terms of Use: https://mousejiggler.lol/terms.html Privacy Policy: https://mousejiggler.lol/privacy.html
