🚗 Car Wash - Smart Car Wash Assistant

Have you ever washed your car only to find it raining right after?
Car Wash is a smart car wash assistant that comprehensively analyzes weather, air quality, fine dust, yellow dust, and even pollen to let you know if now is a good time to wash your car.

🌤️ Today's Car Wash Index
━━━━━━━━━━━━━━━━━━━━━━━
It's not just "It's sunny today."
Car Wash calculates two key scores:

✅ Car Wash Possibility Score
It combines the probability of precipitation, temperature, humidity, wind speed, and air quality to tell you on a scale of 0 to 100 whether it's a good time to wash your car.

✅ Car Wash Durability Score
It predicts how many days your car will stay clean after a wash.
What if it's sunny today but there's yellow dust tomorrow? WashCar will notify you first.
