ACB ONE: Frequent Crashes in Banking App

The problem is that the app experiences frequent crashes and persistent errors, making it difficult for users to complete transactions and navigate the interface. This results in a frustrating user experience, with many users expressing dissatisfaction and labeling the app as poorly designed and unreliable.

97 different people have complained about this since 14 Jul 2022, most recently on 28 Oct 2026. 2 of them in the last 30 days.

Is this a startup idea?

Not directly. These are complaints about a product or service people already use — the fix belongs first to that provider.

    …low này mà ngu quá vậy,performance app thì chậm như thời internet 2G. Một ngân hàng lớn như ACB nhưng trải nghiệm người dùng thì quá tệ và ngu ngục, cho 1* vẫn còn thấy quá cao

    ACB ONE — App quá tệ — Lúc chuyển khoản ko cho lưu người thụ trước, lúc trước thì app có tính năng này giờ thì ko thấy. Làm mất thời gian kiếm thông tin. Chả hiểu mấy cha dev kiểu gì. Ngân hàng thuê sinh viên năm nhất dev app à ? CRUD cũng ko xong.

Questions about this idea

Is Frequent Crashes in Banking App a startup idea?
Not directly. These are complaints about a product or service people already use, and the fix belongs first to that provider. The page shows what is frustrating users and how badly — not an open market to start a company in.
How many people have this problem?
97 different people described it independently, in 97 mentions, the earliest from 14 Jul 2022 and the most recent from 28 Oct 2026. The quotes, with dates and links to the originals, are in the Evidence section.
Is this problem getting worse?
Status: easing — a clearly smaller share than a month before. 2 people raised it in the last 30 days and 15 in the 30 days before; the status compares its share of everything collected from the same source, so collecting more or less cannot create a trend.
