Wondering how today’s allergy forecast will affect your seasonal allergies? Are your seasonal allergies so bad that you always check the pollen count and allergy map before you head out?
The Zyrtec® AllergyCast® app helps take some of the guesswork out of managing your allergies. It uses advanced technology developed by Zyrtec allergy experts to predict how your allergy symptoms may make you feel so you can prepare for each day.

Personalized Predictions at Your Fingertips
When you first download the app, we’ll provide you with the pollen level in your area based on your zip code. Each day for 5 days, you’ll track your symptoms in the app.

After 5 days of tracking, we’ll unlock your personalized symptom predictions. This rating, on a scale from Low to Severe, lets you know how your allergy symptoms should really feel that day. The more you track, the smarter and more personalized our predictions become.

In addition to your daily symptom predictions, you’ll get a fresh-looking app that includes these features:
- Weather forecasts and insights for your zip code that updates based on your current location
- An enhanced allergy symptom tracker
- Allergy trends based on your tracked symptoms and treatments
- A list of the top allergens in your area

Pretty good app

This is one of the better pollen-count apps I’ve used. It’s easy to navigate and it gives you all sorts of information about weather and how it effects pollen count and subsequently your allergies, as well as the pollen forecast. I already know what I’m allergic to so the app didn’t really change much for me. I do wish for some feature changes/ additions: on the tracking log I wish there were check marks for asthma and itchy skin; instead it’s all upper respiratory symptoms. Which I understand with it being a Zyrtec app. It’d also be nice to have a place to check off what pollens you *know* you’re allergic to and get notifications on days when those specific allergens are high. Maybe they’ll see this comment. Regardless it’s a good app to have.

Love this app! Best allergy website or app I have found!

I have used this app for many years, I highly recommend it! Becaus of this app I was able to figure out I’m always sickest when juniper is listed and molds. I was able to tell my allergist who tested for those and more, and it did turn out I was in fact most allergic to those. As we moved, I’ve been allergic to different things and it’s helped me narrow down what causes the most reaction or when I’m on vacation sometimes I will start feeling sick, not sure if I’m coming down with something, often I’ll check the app and find that where I’m at is high in mold or juniper. It’s fun to learn how easily my body detects certain allergens and also more easily help figure out whether I may just be coming down with a cold. I also like the forecast part of it, and have found that to be reliable too. I love this app!

A lot of options ,

Good Experience

I am a newbie but I am having a good experience so far. I really like the fact that I can take a look at what is high in our area. I am also doing the logging in so that I can determine what I’m most allergic to based on the information that the app will provide me. I’m very excited about this. I will continue to use the app. Unfortunately I’m not a daily user but who knows. I will update my review in a couple of months to see where I stand since most of the concerns seem to be after you’ve been using the app a few months.
