What is the major benefit over React (web)? Of course for apps where you need access to the users music for a music player it makes sense, but for festivals for example a web app app should be sufficient.
It ended up being an amazing app store SEO hack, a lot of the time we were the top search result for x festival - that's a lot harder to achieve on a website.
Also, quite simply, people take their phones to a festival not their laptop. This worked offline and tapped into things that only fit well on an app (e.g. find my tent, chat with image upload). It was definitely a lot easier to compete against the official app than website.
