20 twenty 20: Stop eye strain

20 twenty 20 helps you schedule breaks from your electronic devices to prevent eye strain and prolonged physical inactivity. Take short breaks to increase personal health and productivity with the 20 20 20 Rule! Whether you're working at a computer, playing on your phone, or watching TV, sprinkling screen usage with physical activity breaks can have profound effects on your long-term eye and body health.

The 20-20-20 Rule is a simple guideline to prevent Digital Eye Strain (Computer Vision Syndrome) when using your phone or computer:

Every 20 minutes [of looking at a screen], look at something at least 20 feet away for 20 seconds.

This rule isn't only for your eyes. If you get stuck staring at a screen for any length of time, the 20-20-20 Rule reminds you to stand up, stretch, or do another activity to keep your muscles from getting stiff so you don't fall into the unhealthy trap of sitting for too long.

To promote maximum healthiness, 20 twenty 20 will suggest a moderate intensity exercise for every break! Tiny adjustments to your lifestyle can help you better enjoy your time both in front of or away from the computer screen. Sometimes, all it takes is a short activity reminder to help you be your best self. 20 twenty 20 will also let you know when your break time is over so you can get back to enjoying your electronic devices.

Some features:
• Receive automatic reminders when it's time to take a break from your screen
• Exercise recommendations for every break!
• Get notified when you can get back to work/play
• Set your ideal work and break cycle
• Customize how you get notified: ringtone/vibrate/LED (if available)
• Night Mode theme reduces eye strain even more in the evening

If granted, the LOCATION permission is used only in conjunction with the automatic night mode feature to switch themes at sunrise and sunset.

20 twenty 20 is ad-free and open source. Please visit the website for more information.

What's New

By request, some new customization options in the Settings menu:

• Automatic timer switching: You can now turn this off if you want direct control of when the next timer starts. Switching to manual control stops the 20-20-20 cycle when one timer finishes and adds a button to your timer notification so you can start your next work/break timer when you're ready.
• Exercise recommendations toggle: turn this off if you are only interested in eye health break reminders.

Stay healthy!
