Điên đầu *2022-08-30, version 4.2.8* Thông tin mũi tiêm 1,2 mãi ko thấy lên nên mình tự khai. Và giờ thì tiêm đủ 4mũi rồi nhưng mà QR vẫn chỉ hiển thị là 2mũi tự khai còn cái thông tin tiêm chủng đủ 4mũi rồi nó ko thèm lên. Ko sao mà xoá hay sửa đc j. Hễ vào sửa hoặc xoá nó lại báo vớ vẩn linh tinh j ấy ko thì nó đơ luôn ko sao ấn đc chức năng nào. Phải thoát ra vào lại và vẫn là đã tiêm 2 mũi tự khai.

If can give “-10” star I sure give!! ### 1/5 — Sad *2022-06-02, version 4.2.8* Cannot add Medical Declaration because the app doesn’t recognize US number tried many different ways and still problems.

This app is useless and worthless as the developers. ### 1/5 — Constantly crashes *2022-05-05, version 4.2.8* Non-intuitive and constantly crashes. Poor instructions are difficult to follow. US phone numbers not acceptable in the app’s format field. Error messages displayed when attempting to upload scanned or photographed documents. Discouraging and disappointing for a mandatory requirement for entry into a lovely country. ### 1/5 — Extremely Frustrating *2022-05-05, version 4.2.8* This app is horrible. Nothing but problems and frustration. Tried multiple times to download data and input information and was told that I needed to retry only to end up in an endless loop. Absolutely worthless. ### 1/5 — No verification code sent *2022-05-05, version 4.2.8* I tried to register in this app several times and never received any verification code to go forward with the next step!

Tôi đăng ký số điện thoại nhưng không nhận được tin nhắn gửi Mã Số về. Rất nhiều người cũng bị giống tôi. Tại sao 1 chức năng căn bản như vậy cũng không hoạt động? Sao không ai kiểm tra ứng dụng này và fix lỗi? ### 1/5 — Sign in *2022-05-02, version 4.2.8* Send so many times email nothing receive ### 1/5 — Doesn’t work *2022-04-30, version 4.2.8* No OTP received in my email, can’t register my non VN phone number..what is the point of this app again? ### 1/5 — Never got OTP in my email *2022-04-28, version 4.2.8* Trying for the last 3 days registering my email but never received any OTP. ### 1/5 — Unable to sign up *2022-04-28, version 4.2.8* Unable to sign up via phone number or email.

Nhập email bao nhiêu lần cũng báo lỗi ## Most critical reviews (10 lowest-rated) ### 1/5 — Reminiscing of horrible memories *2025-08-15, version 4.3.2* So, they really talked themselves up about what they did in 2020, right? They made this app sound like it was the ultimate solution for dealing with the pandemic. But then in 2021, it all came crashing down, and now people just want to toss this junk into any electronic landfill. ### 1/5 — Không gửi mã otp *2023-06-25, version 4.2.8* Ko gửi mã OTP nên ko đăng nhập đc ### 1/5 — Leaks personal information! *2022-10-30, version 4.2.8* I recently downloaded the app and when opening it today, I noticed it showed all the personal information entered by another person! Name, passport number, email, current address and more. Horrible and inexcusable! ### 1/5 — I can’t even log in *2022-10-22, version 4.2.8* App gives an error message every time I try to enter a phone number or email address. Note that the app has captured my phone number, since I then received a barrage of text messages asking me to log in, which I cannot do. ### 1/5 — Không đăng nhập đc *2022-10-17, version 4.2.8* Đăng nhập bằng sđt xong ko đồng bộ mã QR cá nhân dc.

Mong dev team cải thiện phần UI để app thật dễ sử dụng. Xin cám ơn ạ ### 5/5 — Keeping Vietnam Safe *2021-02-25* Useful app for checking exposure in Vietnam when venturing away from home.
