Expo (formerly Exponent) is a mobile development toolchain built around React Native which includes a robust SDK with cross-platform components, build tools, and asset management, all which ultimately facilitates quick development of iOS and Android apps using React and JavaScript. In short: it makes mobile devlopment easier. Review collected by and hosted on G2.com.

Adding components from libraries outside of Expo might require detaching or ejecting which complicates maintenance, and is required to support features that the Expo SDK does not include. Review collected by and hosted on G2.com.
