Please fix. ### 1/5 — Ad free is not ad free! *2020-01-07* Paid AUD 8.99 for ad free version - still getting google ads taking up 10-20% of screen space. Noticed price had gone up the next day to AUD9.99 - is this a scam??? ### 1/5 — Inaccurate for Australia *2019-12-18* This does not use our standards for calculating AQIs. It was rating air quality as “good” during major fires when the local EPA had a rating of hazardous and there were public health warnings issued! ### 3/5 — Not real time *2019-12-16, version 1.7* Air quality not real time, a lot can and does change in 6hrs. Needs to be much more recent. Apart from that, simply Le App with simple presentation. ### 5/5 — Poor response even after paying for REMOVE ADs *2019-11-29* I paid Rs 159/- for REMOVE ADs but they are still coming and it’s very irritating. Sent two emails to the App Company ## Most critical reviews (10 lowest-rated) ### 1/5 — I CANT BREATHE ANYMORE!!! *2026-08-13* This app really helps me to keep my windows shut and the AC on. We hate fresh air now and don’t go out unless this app lets us. We even have N-91 masks, but don’t dare go outside without goggles and masks on!? ### 1/5 — Brutal ads take over entire operation of phone *2025-09-04* Could be such a good app but gaming ads take over operation of phone once installed ### 1/5 — Just Ads *2025-02-13* Terrible app, half of the screen is covered by ads and you can’t even see the relevant information you actually need ! Too much is too much at times ### 1/5 — Irritating design *2024-11-18* Information seems fine if limited - but if you haven’t paid for an ad free version then an ugly ad takes up most of your phone. I installed and then uninstalled ### 1/5 — 3-30-24 *2024-03-30* No stations in my area Southwest Florida Fort Myers, Naples ### 1/5 — Outside Thick With Smoke *2023-11-07* This morning the air outside is thick with smoke yet the App is saying air quality is good! So therefore the App is useless in warning me of amy problem with pollution. ### 1/5 — Nice idea but not enough *2023-04-09* Would love to know the PM2.5 but for my city not just my location. The app requires you know and input your local station manually. This is time consuming and you have to know what they are. Other apps like IQAir just automatically find the local sensors. Not enough functionality. ### 1/5 — Not up to date *2020-09-12* Consistently hours behind.... ### 1/5 — Ads BS *2020-09-06* I do not appreciate your ads popping up while I’m looking at something. ### 1/5 — Not timely *2020-01-08* Updates are 2 hours ago. We need current updates ## Most praised reviews (10 highest-rated) ### 5/5 — AQI *2026-01-08* Good app ### 5/5 — Air Quality App *2025-08-03* Rocks ### 5/5 — Your app is malfunctioning *2025-01-15* Your app is malfunctioning ### 5/5 — Good app *2022-06-19* Pretty precise ### 5/5 — Good air quality app *2022-06-15* Check every day ### 5/5 — Good air quality app *2022-06-14* Use it daily ### 5/5 — Quality app *2022-06-13* Check air quality correctly ### 5/5 — Great job *2022-06-08* Handy and practical. ### 5/5 — All good *2022-06-07* Good ### 5/5 — Air quality app *2022-06-01* Ok --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
