The old version was fast and easy to use and allowed you to quickly have an overview on the map what’s going on + allow you to click on a location and get detailed numbers and charts of them. Now all of those details are gone. Well done HK gov employees… ### 1/5 — cannot use in ios15 *2021-10-21, version 1.5.4* please fix ### 3/5 — Problem after iOS update *2019-10-13, version 1.4.1* Cannot click into “i” information icon in Station Map. Please fix. ### 3/5 — General impression *2018-10-09, version 1.3.5* Looks so old fashioned interface and it would be great if there is more detailed info like pm2.5 n pm 10. Need improvement ### 4/5 — Nice app, with room for improvements *2017-03-29, version 1.2* The app is useful! It would be even better if widgets is available so that I could check the AQHI easily:) ### 4/5 — Notification improvement *2016-12-06, version 1.2* Suggest add the notification badge icon for AQI by location based that able to update automatically. ### 4/5 — Why *2016-04-19, version 1.2* Why don't implement into the HKObservatory app? ### 3/5 — There is no pop up notification *2014-12-18, version 1.2* Dear Admin, I'm using a iPhone 6 Plus with iOS 8.1.1. Although I activated the notification when AQHI reach Very High and Serious levels for both Roadside and General Air Monitoring Stations, there is no pop up notification from the App. I would be most grateful if you could follow up the issue as the pop up notification is very important to me. Best Regards, Edwin YU ### 4/5 — Great app to keep away from pollution *2014-08-06, version 1.2* Definitely going to make us of it daily basis. ### 4/5 — Please Push Low risk reminder *2014-02-06, version 1.2* Please also push notification when the index is low so that I can plan outdoor activities. Generally a very useful health apps with accurate and detailed information about the current AQHI and also suggested measures. The apps also has a nice UI. But the following areas can be improved: The app uses users' location service but users still need to choose the district or station they want to receive notification about. This is not intelligent enough. If the apps can take advantage of the GPS location and smartly pushes notification about the AQHI of that area, that would be NICE 😄 ## Frequently asked questions about HK AQHI 香港空氣質素健康指數 ### What is the AQHI?
