5 stars: Easy to use. It would be much better if GPS tracking of me can be done so as to minimize the risk of getting transmitted. Personal data collection is normal and the the whole purpose of the app, similar to the Singaporen one.
5 stars: Access to restaurant is fast and it is convenient wherever I go I can use this as pass before dine in or going in malls & hospital too.
4 stars: Easy to use. I don't know what other users are complaining about on personal info collection. Practically all apps have the declaimer saying personal info such as pictures and locations will be collected without asking for further approval. You either use a smart phone or you don't. Personal data are collected as soon as GPS is opened. I don't understand why users are delighted personal data to be collected by US developers but not HK.
4 stars: Scan code always delay Better have notification like 'you are visiting xxx' so user can tap it n rmb to click leave
3 stars: Needs ability to edit entry time as may forget to scan till later eg taxi, scan at table etc. Make things easier for elderly. Clicking on green 'Vaccination Record' button on front page, right bottom - if empty, no record, it should ask if the user wants to scan in their record and take them to that part of the app if they answer Yes ; instead of saying it is empty with no indication of how to enter the record.
3 stars: One can realize that I have had taken the 4th vaccination but the record is showing the other...
