Convenience and speed are top two factors.
Tech performance firm Compuware conducted a global study of consumer mobile expectations and experiences to find that 85 per cent of respondents prefer apps to mobile websites.
55 per cent say apps are more convenient, 48 per cent say they're faster, and 40 per cent say they're easier to browse. Apps aren't just being used for personal tasks like shopping, booking hotels and travel either, with users saying they simplify office tasks and colleague-based communications.
Despite the apps being more popular, 62 per cent have experienced crashes and errors, 47 per cent cite slow launch times, and 40 per cent have tried an app that wouldn't even launch.
Stephen Pierzchala, technology strategist, Compuware APM Center of Excellence, said: "With consumers expecting greater experiences with mobile apps now more than ever, fulfilling those expectations doesn’t just happen -- it takes a conscious effort throughout every stage of the design and development process to get it right.
"Performance is a crucial contributor to providing a dependable mobile app user experience, so performance should be considered a key driver in the design process. Mobile applications need to focus on a core utility, and they need to be fast and reliable in order to be valuable."
