We chose React Native over native Android and iOS development because of React Native's cross-platform capabilities. React Native has really matured over the years, developing a native feel, with simple and intuitive APIs. The community is also huge, filling in any gaps in the default APIs. These are also the reasons why we didn't choose other hybrid mobile tools. Largely, other hybrid mobile tools don't have the same mobile feel and close connection to the underlying mobile APIs.
At a larger scale, the control that native development offers beats React Native's simplicity. However, at this early stage, it's worth the trade-off. Maintaining two mobile teams and two mobile apps, as we iterate the product rapidly would not be practical. Plus, there is always the escape hatch of native modules if more control is needed.
