Cross-continent analysis reveals shared and unique app feedback patterns in South Africa, suggesting cultural influences on user concerns.
Understanding customers’ feedback is essential for businesses to improve products and adapt to different markets. This study analyzes 100,000 app reviews from Uber, Instagram, and WhatsApp across six countries (Brazil, U.S., Australia, India, U.K., and South Africa) to assess whether user concerns are global or culturally influenced. Using BERTopic for topic modeling, zero-shot classification for topic assignment, and Aspect-Based Sentiment Analysis, we identify twelve key topics in reviews. While some topics are shared globally, others are country-specific. For example, Uber’s reliability was a major concern in South Africa and Australia, while Brazilian users discussed WhatsApp voice messages more frequently. These findings help businesses detect market-specific trends, benchmark competitors, and address regional needs strategically.
