We maintain a few number of projects for clients - the apps are feature complete and will not change much in the next years. The goal here is to spend not much money on the apps but to keep them functional in the appstore. RN is somewhat cheaper up fron than native development or say flutter. Unfortunately, maintenance cost is high and difficult to predict. Why? Appstores are adding new requirements and increase API-level all the time. Support for that is often baked into new RN versions. Unfortunately, new RN versions often break things, which break libraries in turn. So you need to upgrade this morass and if you are unlucky, you need to redevelop huge swaths of your app because the lib now is deprecated /works differently / will never be updated to the new RN version.
