As the lead developer on this project, I have mostly web dev experience with only a bit of mobile dev. Because of this, I looked for cross-development frameworks that were free, and easy to pick up. React Native seemed to be the most well-documented and accessible x-platform mobile dev framework. I also had a bit of React.js experience from toying around developing web apps. The accessibility, ease of use, and community support were the primary reasons I chose to use React Native for our internal mobile app.
