Every product conversation eventually reaches the same question: should this be a mobile app or a web app? The honest answer is that it depends on who your users are, how often they will use the product, and what device behaviour you need, like push notifications, offline access or camera integration.
We usually start client engagements with a short discovery phase specifically to answer this question properly, rather than defaulting to whichever platform is more exciting to build. Getting this decision right early saves significant time and budget later.
