In recent years, the shift towards a mobile app-only strategy by businesses has proven to be problematic, leading to significant challenges in customer engagement and sales. Despite the initial allure of mobile apps, studies reveal that a high percentage of users abandon apps shortly after downloading them, with 57% of users churning within the first month. Companies like Flipkart and Myntra experienced setbacks after adopting app-only approaches, with Myntra seeing a 10% drop in sales and eventually reverting to mobile web platforms to regain traction. The inefficiency of app-only models lies in limited user reach, high costs, and complex development demands. In contrast, mobile-friendly web apps offer broader accessibility, lower costs, and simpler maintenance while achieving higher conversion rates. Successful examples, such as Jumia's use of Progressive Web Apps (PWA) and Lancôme's mobile web optimization, demonstrate the advantages of focusing on mobile web strategies. As consumer behavior increasingly favors browsing over downloading apps, businesses are encouraged to adopt mobile-first web designs to effectively capture and retain their audience.
