About the app
The ZYRTEC® AllergyCast® application serves as an essential tool for tracking allergies and forecasting pollen levels, helping you manage your allergy concerns effectively. By utilizing local information such as pollen counts, air quality, and weather conditions, it generates a tailored allergy impact score that predicts how your seasonal allergies may affect you on a daily basis. Consider it a "real-feel" forecast specifically for your allergies!
Curious about the current pollen levels? With AllergyCast®, that information is readily available, along with additional features. The app does more than just provide pollen counts; it also delivers personalized predictions regarding daily symptom severity. By logging in, you can monitor your symptoms and gain access to progressively accurate predictions over time.
Upon starting the app, you will receive a local pollen forecast alongside a basic prediction of symptom severity. For enhanced personalization, regularly log your symptoms. Each day, you will obtain predictions for allergy symptom severity as well as forecasts spanning multiple days, taking into account your recorded symptoms and the current weather conditions.
If AllergyCast® indicates a "Mild" day, you may experience fewer allergy symptoms. However, if it predicts "Severe" symptoms, it might be wise to prepare accordingly.
Key features of the AllergyCast® App include:
- Forecasts for multiple days detailing symptom severity, pollen levels, weather, and air quality based on your location.
- Interactive maps showing pollen and air quality levels along with prevalent allergens in your region.
- A comprehensive allergy symptom tracker and a customized Allergy Profile.
- Insights tailored to your allergies, identifying specific pollens that could trigger reactions outdoors.
- Trend analysis based on your recorded symptoms, including a customized Allergy Profile.
- Exclusive discounts, coupons, and promotional offers on ZYRTEC® products.
