Many device APIs are supported (check out the "SDK API Reference" in the sidebar), but not all iOS and Android APIs are available yet
: need Bluetooth? Sorry, we haven't built support for it yet. WebRTC? Not quite. One of the most frequent requests we get is for In-App Purchases and Apple and Google Pay integration. We haven't built this yet, but it's on the roadmap. We are constantly adding new APIs, so if we don't have something you need now, you can either use ExpoKit or follow our blog
to see the release notes for our SDK updates. Feature prioritization isn't stricly based off of popular vote, but it certainly helps us to gauge what is important to users.
