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 you track your local pollen index each day and see how pollen might really make you feel with ALLERGY IMPACT. It’s like a real-feel allergy forecast for your allergies.

Unlike static maps and figures, ALLERGY IMPACT analyzes weather information from 41,000 zip codes, search and social media trends to tell you how the pollen count may make you feel. It uses multiple factors to determine whether or not the pollen count could affect your allergies. If the ALLERGY IMPACT for the day is higher than the pollen count, you might feel allergy symptoms like sneezing and itchy eyes more than you’d expect. If it is lower, your allergies might not feel as bad as the pollen count suggests that day.

Here is how ZYRTEC® ALLERGYCAST® with ALLERGY IMPACT can help you better manage your day:

• Daily ALLERGY IMPACT and pollen count to help you plan your day.
• Hourly, 10-day weather, and allergy forecasts in one place.
• Enhanced symptom tracking to help you learn what is making you sneeze.
• Multiple profiles to track your symptoms and those of loved ones.
• Customizable notifications alert you when pollen is high in your area.
• Updates on how pollen is affecting other allergy sufferers in your area.

Strange app

I’m not sure the point. I thought it would help me track symptoms and correlate that with the air quality status with regard to pollens, dust etc. there doesn’t appear to be a way to go back and pull data from previous days. Other parts are equally unclear. There is a symptom input panel on a screen that gives a score that the pollen counts are essentially at the max amount, yet the provide some arbitrary score that tells me that I shouldn’t have any symptoms because that same measured amount is not high. I deleted it. I’ll use my accuweather app to track the amounts and keep my own data in Numbers spreadsheet.

No notifications!

This used to be a great app till several months ago when location settings stopped working. Also notifications stopped coming in although I had everything set properly. So I deleted and re-installed a few times. Still didn't work. I installed it again last week, and so far Location is working, wish I could say the same for notifications. STILL NOT getting them! Please please please fix this so notifications will work! There's much to love about this app if the location settings and notifications would work.

When It Works

Today is 30 Dec 2017 app showing data for 17 Dec 2017 on my iPad. Same app on iPhone showing data for 15 Dec 2017. Nothing will correct the data. Seems app just doesn’t work properly several times a year. The times it does work it’s very useful.

6 March 2018. Raining here App says pollen count same as yesterday which was windy sunny day with count of 6.1. All other pollen readings from other sites pollen count is 2.2 for today. A nice & useful app when it works. Apparent Zyrtec pays no attention to their app.

9 June App not updating again for iPad/iPhone for least week. Deleted app and reloaded that does not help.
