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?! ### 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. ### 3/5 — Eigentlich ganz gut, aber… *2024-05-28* Die App ist richtig gut, allerdings habe ich die App irgendwann deinstalliert, weil ich mich registrieren muss, um meine Allergiesympthome zu tracken. Irgendwann habe ich dann aber die Möglichkeit, die Pollen zu checken, vermisst. Ich habe sie also wieder installiert, aber als ich nicht sofort die Standortdaten und die Benachrichtigungen aktiviert hatte, hat die App irgendwie gesponnen. Es tut mir sehr leid, das Design ist sehr ansprechend, und auch ist es sehr einfach, sich zurechtzufinden, aber das war leider nicht der Bringer. Ich habe mittlerweile eine andere App gefunden, wo ich ohne Anmeldung meine Symthome tracken kann, es muss nicht einmal regelmäßig sein ### 2/5 — Tracking *2024-05-20* When I open the app it asks me to select my country, allow location, allow notifications but then it just get stuck on a screen that says ‘tracking will allow us to…’ and I can’t use the app, I have closed it ,opened it, deleted and reinstalled the app and turned my phone on and off **Developer response:** Hello, thanks for sharing this feedback. I am really sorry you are experiencing this issue, please contact us directly - support-uk@klarify.me and we will help to rectify the issue. Best wishes the klarify team ### 2/5 — Not sure… *2024-04-28, version 25.2* Well..have installed app but I clicked allow and all the things and it’s on a blue screen which says:Tracking will help us understand how our content is working for you so we can improve it.Were grateful for your support’’ and so it’s just stayed like that for the past 5-10 mins.wonder if you know what to do to fix it? ### 4/5 — Klarify *2024-03-04, version 24.4* Ako dlhoročný alergik, odcenujem túto appku. Pekne spracovaná a dobre sa v nej orientuje. Pridal by som možnosť, zapisovania si vlastných poznámok ku každému dnu. Predvolené možnosti odpovedi nie vždy vystihujú daný pocit. ### 4/5 — Colour blindness *2023-09-03, version 24.0* Nearly 10% of men are colour blind and the majority of them are red/green colour blind. Can you improve your indicator colour schemes to brighter colours to help us afflicted please. ### 4/5 — Great allergy tracker, but it leaves out mould spores. *2023-07-22, version 23.0* I would give it five stars if it also tracked mould spore levels. Otherwise great for helping to track your allergies, especially if you fall in the classic hay fever camp. ## Most critical reviews (10 lowest-rated) ### 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) ### 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. ### 1/5 — Air quality daily forecast graph gone. *2025-03-06* Edit: now there is no Pollution rating number. Pollution is a major contributing factor to lung health, to remove it degrades the usefulness of the app. Latest update removes the useful daily air quality forecast graph and replaces it with one number for the current time only. This means we are unable to plan our daily outdoor activities so we avoid going out when the air quality is forecast to be poor. Now it’s pot luck. **Developer response:** Hi Squashbag, thanks for your feedback; which has been passed on to our app team. If there's anything further you'd like to share to enhance users' experiences of the app, please get in touch - support@klarify.me Best wishes, the klarify team. ### 1/5 — Unbrauchbar *2024-08-10* Man kann seine Symptome nicht differenziert eingeben (z.B. bei der Nase heißt es nur allgemein laufend, verstopft, juckend. Was ist mit nur Niesen, wenn alles andere nicht zutrifft). Auch die Intensität jedes Symptoms lässt sich nicht eintragen. Nur eine allgemeine Aussage wie sich sich die Allergien auf einen auswirken lässt sich auf einer Skala von gar nicht bis sehr stark eintragen. Die Krönung aber ist die „Auswertung“ der Daten, der sog. Allergie-Log. Hier kann man sich lediglich die vergangenen 7 Tage in einer Grafik darstellen lassen. Über einen ganzen Monat oder Monate ist dies nicht möglich. Wenn man einen bestimmten Zeitraum betrachten möchte, muss man umständlich zurück scrollen. Einfach nur nervig und wenig intuitiv. In der Monatsansicht kann man lediglich einzelne Tage anklicken. Auch habe ich keine Möglichkeit gefunden wie man sich die Auswertung zusenden lassen kann oder wie man die Daten exportieren kann. Diese App nutzt nur dem Hersteller etwas, der persönliche Daten sammeln kann, mit der er nach gut dünken verfahren kann und die dann sonst wo landen. Prädikat: Unbrauchbar! **Developer response:** Vielen Dank für die guten Ideen und Anregungen. Wir verstehen gut, warum die beschriebenen Funktionen hilfreich wären und werden mit unserem Team daran arbeiten. Bezüglich der persönlichen Daten können wir dir versichern, dass wir strengen Datenschutzverordnungsrichtlinien folgen, die selbstverständlich auch in unserer Datenschutzerklärung beschrieben sind. Solltest du weitere Fragen oder Anmerkungen haben, freuen wir uns auf deine Nachricht: support@klarify.me. Viele Grüße, dein klarify-Team ### 1/5 — Incorrect Levels *2024-03-05* The app had my location correct but was suggesting allergists for LA. I am in Texas. I don’t know if the levels were based on my location or LA. It was completely incorrect if my location. It said the allergen levels were low, but they are high today. **Developer response:** Hello and thank you for your feedback. The klarify app uses the pollen data collected and analysed by Google - the technology covers over 65 countries worldwide. I'm really sorry that you're experiencing this issue. The Find a Doctor tool can search for participating allergists in an area by inputting the desired location into the search. If we can help more specifically, do get in touch so that we can better understand what's going on. Best wishes, the klarify team (support@klarify.me) ### 1/5 — Incapable d’utiliser l’application *2023-07-18* J’ai téléchargé **Developer response:** Bojnour, nous vous remercions pour votre message et sommes désolés pour les inconvénients. Nous espérons avoir résolu le problème maintenant. Nous apprécierons un court message si l'application fonctionne à nouveau. Merci de votre compréhension ! Cordialement, klarify ### 1/5 — Everything was in French *2023-06-25* Everything was in French? Couldn’t get past the first page. Most Canadians speak English fyi. **Developer response:** Hi ScottE83, thank you for your review... language settings default to the native language for any country - but, Canada has two options: French and English. The app team suggest deleting the app and then re-installing it. You should be given a choice of language setting ... if you have issues, please let us know - (support@klarify.me) - we'll investigate the issue further. Best wishes, klarify ### 1/5 — Air quality daily forecast graph gone. *2023-06-08, version 19.4* Latest update removes the useful daily air quality forecast graph and replaces it with one number for the current time only. This means we are unable to plan our daily outdoor activities so we avoid going out when the air quality is forecast to be poor. Now it’s pot luck. ### 1/5 — Zbytečná věc *2023-05-19, version 19.3* Mně teda oproti ostatním přijde, že Vám aplikace neposkytuje žádné info, které byste neměli v běžném pylovém kalendáři. Spíš to celé působí jako další aplikace, která z Vás tahá data pro výzkumné a podobné účely - např. jak se dnes cítíte atd. ## Most praised reviews (10 highest-rated) ### 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 ### 5/5 — Keine Nutzung möglich *2024-05-17, version 25.4* Ich hab die App vor ein paar Jahren sehr regelmäßig genutzt und brauche sie nun wieder. Allerdings kommt beim Tracking erlauben einfach kein Pop-Up 🥲 Dadurch ist die App nichtmal ansatzweise nutzbar. Update: Funktioniert endlich wieder :) Danke! ### 5/5 — App keeps updating takes at least 30 min *2023-12-30* Then it works for a short while and starts updating for another 30 minutes and so on and so on I love this app. I hope you can fix it! **Developer response:** Hi there, it's good to hear from you again! We're sorry you're experiencing this issue - the new app version necessitates the password to be strengthened to comply with standard password requirements... please email us and we can help further! Best wishes, the klarify team. support@klarify.me ### 5/5 — Great Allergy Tracking App *2023-12-17* I was looking for an app that provided detailed information on the individual allergens. In my case juniper. It provides very low, low, med, high, none/out of season. I have to start watching Juniper the minute it starts to bloom. This app is a great help to me! **Developer response:** Hey, Thanks for leaving us a 5* review, we really appreciate it! We are so pleased our app is helping. Keep in touch we love to hear from you. Best wishes the klarify team ### 5/5 — Super App! *2023-11-16* Sehr übersichtlich und schön gestaltet. **Developer response:** Hallo nochmal, Vielen Dank für deine 5-Sterne-Bewertung!

Moc pomáhá i mé alergoložce ### 5/5 — Great! *2023-10-15* Love being able to see local allergens while tracking my symptoms and treatments. **Developer response:** Hey, Thanks for leaving us a 5* review, we really appreciate it! So pleased you are finding our app so helpful.

Wir freuen uns, dass dir die App gefällt. Viele Grüße, dein klarify-Team ### 5/5 — Amazing *2023-06-16, version 19.4* It’s really helping me and what to stay away from also I love the avatars😂 ### 5/5 — Helpful and easy to use *2023-06-14* Great app - in addition to the usual allergens that its competitors use, it also provides Tree data which allows me to correlate and track my health issues much better! **Developer response:** Hi Redstarfreedom, thank you for your 5* review!
