About this app

Using your smartphone too much makes the water cloudy.
WaterCore is an app that represents screen time not as "numbers," but as "the clarity of water."
You can see how much you've used your phone today just by looking at the water on your screen, instead of looking at numbers. If it's clear, it's been a good day. If it's cloudy, you might want to take a break.
✦ Features
• Simple UI with no numbers
• Set daily target time with a slider
• Visualize categories like SNS, videos, and games with different colors
• Intuitively grasp screen time just by looking
Instead of being chased by numbers, try re-evaluating your relationship with your smartphone, as if you were having a conversation with water.
