Schedule screen breaks with a 20-20-20 preset, a clear countdown and optional sound cues. Customize focus time and break length.
Use the tool
Choose units, measurements or a session preset. Review the supported scope beside the controls.
Adjust the plan and review the visual result. For a timer, select Start; Pause, Reset and Next remain available where applicable.
Save a private summary, schedule or log if offered. Nothing is uploaded or automatically saved.
Understand the method and limits
The 20-20-20 preset follows AOA guidance: every 20 minutes, look roughly 20 feet (6 m) away for 20 seconds. Customize if needed. Not treatment or an eye exam. Keep the tab open for timing; sessions pause when hidden and sound cues depend on browser support.
Keep your information private
Inputs and logs stay in page memory. No account, upload, health-data analytics, browser storage or medical-record synchronization. Leaving or refreshing the page can clear the session; explicitly downloaded files contain your information. Exports are local PNG/PDF summaries, CSV schedules or logs, and a sleep calendar where offered. These tools are for general planning and estimates, not diagnosis or individualized treatment.
Try the workflow
Keep your original documents and review the output. You can also browse all guides or contact Team Hypomnema.
