### 5/5 — Noch Ausbaufähig aber Super

*2026-01-04, version 26.1.0*

Ich persönlich mag die App, sie ist aber noch Ausbaufähig. Man kann zum Beispiel seine persönliche Vorhersage noch nicht Personalisieren oder aus einer gewählten Interaktion manchmal nicht heraus,weil das Program hängt. Aber sonst bin ich völlig zufrieden

### 3/5 — Stopped working

*2025-12-03, version 26.1.0*

App is not working post upgrade.

### 1/5 — Loading…

*2025-09-12*

Doesn’t work. Just says loading. Reinstalled twice.

**Developer response:** Hello and thanks for this information - we'd like to help with this issue, so sorry you've experienced it! Please email screenshots/recordings of any problems so the app developers can look into this for you. Best wishes, the klarify team. (support@klarify.me)

### 1/5 — App doesn’t work …

*2025-08-25*

I wanted to like this app & thought it would be helpful, but it jams up 1/2 way through loading & won’t load any actual information other than air quality ! 
I even removed it & re-added the app, but this only fixed the problem that 1 time …

**Developer response:** Hello and thanks for this valuable feedback - we'd like to help with this issue, so sorry you've experienced it! Please email screenshots/recordings of any problems so the app developers can look into this for you. Best wishes, the klarify team. (support@klarify.me)

### 2/5 — Doesn’t work

*2025-05-22*

Great concept but the app does not function. Tried logging in and got stuck on the page where you press “allow” or “don’t allow” regarding data. Closed the app and went back on it, successfully logged in and then tried to log first day of symptoms but nothing happens when I press confirm. It just isn’t functioning unfortunately and it isn’t worth having to restart the app for

**Developer response:** Hey, I am sorry you are experiencing this issue, please contact us directly, support@klarify.me and we can work with you to rectify this. Best wishes, the klarify team

### 4/5 — So far so good

*2025-05-21*

Only had this app for a month and so far am loving it. The interface is clear, clean, and simple. Everything is there is an easy to see and use interface. My only criticism and it’s a niggle would be to have an overall layout where you can see all the pollen types and your log of how you felt that day as well as being able to filter to the specific pollen types

**Developer response:** Hey, thanks for leaving us a great review and sharing your feedback, we will certainly take it on board. Best wishes the klarify team

### 3/5 — Decent but inaccurate

*2025-05-08, version 25.8*

I like using this app to track my symptoms- however the allergy calendar is clearly incorrect for grass in the UK.. no allergies in May are you kidding?!

### 1/5 — Useless

*2025-03-26*

No pollen claim when I’m drowning in snot and about to rub my eyes out.

**Developer response:** Thanks for your feedback - so sorry to read about your symptoms! The pollen data used by the app is drawn directly from local sources; I'm sorry that you feel there may be a discrepancy. Ensuring your location is enabled may help with more accurate data. (And, please do see your doctor if you're concerned by any symptoms). Best wishes, klarify.

### 4/5 — yay hayfever!

*2025-03-12, version 25.8*

i get really bad allergies but this app offers advice, metrics and tracking options! the information of levels of pollen is pretty cool, and the information provided useful! one thing i wish i was able to do was make individual notes when logging my symptoms in the day, so a daily notes feature!

### 4/5 — Tolle App

*2025-03-10, version 25.8*

Eine hilfreiche App, die visuell sehr ansprechend gestaltet ist. Ich fände es super, wenn man die durch Tests bestätigten Allergien (z. B. Birke, Erle etc.) hinterlegen könnte und dann täglich eine personalisierte Einschätzung erhält, wie belastend der Tag voraussichtlich wird. Dann wäre die App in meinen Augen perfekt.
