How long will users really wait for loading before abandoning your product? And can loading indicators make that wait feel more tolerable? A study by Fiona Fui-Hoon Nah explored these exact questions. Participants were split into two groups: Group 1: Users who saw a progress bar while waiting. Group 2: Users who had no visibility of progress at all. The results were striking! Participants in Group 1 had a median waiting time of 22.6 seconds , more than twice the 9 seconds of Group 2 . This clearly demonstrates that providing visual feedback during waiting can greatly improve user patience and keep them engaged. In this article, we’ll explore progress indicators in depth—covering common types, variations, and best practices for applying them effectively.  Let’s get started!  What is Progress Indicator? A progress indicator ux is a UI element that shows users their current progress in a process and how much remains to be completed. By giving users a clear view of the proces...

In design thinking, understanding users is always the foundation of creating meaningful products! From the very first stages, UX researchers rely on interviews, observations, and data analysis to uncover what users need and why they behave in a certain way.  However, as digital products grow more complex and user expectations continue to rise, the research process has become heavier. Teams now face the challenge of processing large volumes of data to understand user needs and uncover meaningful patterns. This is where AI is beginning to reshape the workflow. Instead of spending hours sorting feedback or identifying patterns manually, AI helps teams analyze data faster, reveal deeper insights, and focus more on strategic decision-making. In this blog, we’ll explore how to use AI tools for UX research across different phases of design thinking, the limitations, and 7 of the best AI-powered tools every UX researcher should know in 2026. How to Use AI Tools in UX Research Research is ...

Bạn có từng loay hoay giữa hàng tá ghi chú, file khảo sát hay dữ liệu nghiên cứu mà vẫn không thể ghép lại thành một bức tranh rõ ràng về người dùng? Thấu hiểu người dùng chưa bao giờ là việc dễ dàng — nhất là khi thông tin nằm rải rác và mỗi thành viên trong nhóm lại có một góc nhìn khác nhau. Không ít đội ngũ thiết kế, dù đầy tâm huyết, vẫn rơi vào tình trạng xây tính năng theo cảm tính nội bộ, thay vì dựa trên insight thật. Vậy làm sao để thoát khỏi góc nhìn chủ quan và thật sự đặt mình vào vị trí của người dùng? Câu trả lời nằm ở Empathy Map — công cụ giúp bạn trực quan hóa cảm xúc, suy nghĩ và hành vi của người dùng, từ đó giúp cả đội ngũ thấu hiểu người dùng sâu sắc hơn và cùng nhìn về một hướng trong suốt quá trình thiết kế sản phẩm. Trong bài viết này, Lollypop sẽ cùng bạn khám phá Empathy Map là gì, cách thức hoạt động, và quy trình xây dựng một biểu đồ thấu cảm hiệu quả — để mỗi quyết định thiết kế đều bắt nguồn từ sự thấu hiểu thật sự. Bắt đầu thôi nào! Empathy Map là gì? Em...

In the SaaS landscape, retaining customers often delivers greater long-term value than acquiring new ones. Subscription-based models rely on consistent revenue streams, and even minor retention gaps can escalate into significant revenue losses over time. Each churned customer represents more than a dropped subscription; it signals a potential breakdown in user experience, perceived value, or ongoing engagement. Every lost account is also a missed chance to build stronger relationships and increase lifetime value. This is why SaaS churn rate is one of the most critical SaaS metrics you should track and manage carefully. In this guide, we will explain what churn in SaaS means, how to calculate it, the types, benchmarks you should track, why it's important, and how to reduce it, helping you spot gaps before they impact growth. What is SaaS Churn Rate? SaaS churn rate measures how many customers or how much recurring revenue your business loses over a specific time frame. It’s a metr...
