About this app

The ZYRTEC® AllergyCast® app is your go-to allergy tracker and pollen forecast tool, eliminating the guesswork in managing allergies. Using local data like pollen count, air quality and weather, it provides a personalized allergy impact score, predicting how your seasonal allergies will make you feel each day. Think of it as a "real-feel" forecast for your allergies!

Wondering about today's pollen count? Get that and more at your fingertips with AllergyCast®. Beyond just pollen counts, the app offers personalized daily symptom severity predictions. Sign in, track your symptoms, and unlock personalized predictions that get more accurate over time.

When you start using the app, you'll receive a local pollen forecast and a generalized symptom severity prediction. Consistently log your symptoms for more personalized predictions. Each day you’ll receive daily allergy symptom severity predictions and multi-day forecasts, factoring in your tracked symptoms and local weather.

It's OK. I've been tracking my symptoms for a while now, and the app apparently still doesn't have enough information to provide me with my allergy profile, which I find weird. At one point, I gave up, but this time, I've been tracking for a few weeks now, pretty consistently. Apparently, that's still not enough data? otherwise, the predictions seem helpful for the most part ... but I don't get the sense that this is super reliable at this point. I'm sure how long Im supposed to keep tracking .

Loving this app so far. I haven't had it super long, but I really enjoy it. I was looking for an app that just told me the pollen count in my area, but I came across this one and it lets me track my symptoms and treatment. You log your allergies every day for a few days and based on allergens in the area, it will predict your allergies for the day. Great use of notifications too. Only 4 stars because you can make multiple logs a day, but not fix old ones. If they could fix that, I'd give it 5!

Would be nice to be able to input what specific meds you used & select it to see what meds worked & didn't. It'd also be nice to maybe to add fatigue & maybe bloody/burning/itchy nose, coughing, & other symptoms like that as well. Maybe let us edit past entries if we realized we put down something wrong like that we didn't take a med or something, unless I just don't know how to do it. I haven't used it very long but want to long term, so these are just my initial thoughts. Cool app idea.
