Hybrid apps, by contrast, allow developers to write a single code base that is compatible with more than one operating system. It is for this reason that hybrid app development is easier and more cost-effective than conventional app development. Consequently, companies think about investing in hybrid app development more and more. That's also why this type of mobile app creation has become increasingly popular. The hybrid app development model is already being used by major global players including Amazon, Nike, Walmart, Etsy and more. The result is that 74% of the top 50 iOS retail apps in the US are hybrid.
