### 2/5 — Broke

*2026-07-22, version 6.25.0*

How long is this app going to be down. Been down for about a week

### 5/5 — Log Your Allergies

*2026-06-02, version 6.25.0*

Seasonal allergies leave you feeling pretty out of control a lot of the time. Logging my symptoms and being able to reliably predict my weekend is crucial. I’ve learned a lot from this app.

### 5/5 — Ridiculous to ask for password every other time.

*2026-05-04, version 6.25.0*

Ridiculous to ask for password so very often.

### 1/5 — They steal and sell your data

*2026-02-09, version 6.24.0*

They have no need for user data.  The app was created to collect or steal and then sell the user data to others.

### 1/5 — Stopped working

*2025-05-14, version 6.21.0*

I liked this app when I first downloaded it but it has since stopped working, perhaps after the latest update. The app works beautifully when you login for the first time, but any time you open the app after that initial login it just shows “Calculating”. I’ve rebooted my phone and uninstalled/reinstalled the app but the problem persists.

### 1/5 — Doesn’t Work

*2025-05-06, version 6.21.0*

I downloaded the Zyrtec app yesterday (May 5, 2025) because I suffer from severe allergies and needed a reliable way to monitor pollen levels.

Initially, the app performed excellently, providing quick and accurate information.

However, this afternoon, my wife and I went for a walk, so we drove to the park and I opened the app, but it failed to function!

I tried restarting my phone and the app multiple times, but it was still unresponsive, showing a message that it was calculating. Despite my efforts, it continued to display “calculating” without any results.

After our walk, I kept the app open to see if it would eventually provide an update. After 56 minutes, it was still stuck on calculating.

I’m very disappointed that I couldn’t depend on the app for information before my walk.

As a result, I’ve decided to delete the app. If I can’t trust it to work properly the first time I really need it, I doubt its reliability in the future. It raises concerns about the accuracy of the information it provides, especially if it can’t even deliver basic updates or notify users of system issues.

For me, this is an easy decision, and I will delete it after posting this review.

So, proceed with caution if you choose to use it. It may or may not function as intended.

Good luck.

### 3/5 — Spinning cursor and nothing more

*2025-04-25, version 6.20.0*

I have an iPhone 15 Pro with iOS 18.4.1. All I get is the spinning cursor that doesn’t stop. I have 53 gigs of free space on my phone. What am I supposed to do to get it to work?

### 1/5 — Totally inaccurate

*2025-04-18, version 6.20.0*

My local news weather report says that tree pollen is high, and will be for the next few weeks, yet this app says it’s low and will be low for the next few days!  
I have been using this app for the last year, and every time my allergy symptoms flare up, this app is always wrong, and different from local weather reports on tv

### 2/5 — Great at first

*2025-04-16, version 6.20.0*

I really love this at first but now every time I try to go into it it just keeps spinning and won’t open and I have to delete it and re-download it for it to work. Completely annoying. I will stop using it.

### 3/5 — Loading Issues

*2025-04-14, version 6.20.0*

When the app works it is awesome. It seems to have issues every other day where it does not load, so I have to delete the app and reinstall to get it to work. I cannot find any help to figure out why it will not load.
