Pollen.day gives a simple daily pollen score for cities across the U.S. Instead of showing raw pollen numbers, it turns tree, grass, and weed data into an easy 0–100 score so you can quickly tell what the day may feel like for allergy sufferers. You can check today’s condition, see tomorrow’s forecast, and get the update delivered to your inbox every evening. The site focuses on major U.S. cities and uses fresh pollen data each morning from the Google Pollen API. It’s built to help people plan ahead and understand allergy conditions without digging through complicated charts.
