Update (04 Feb 2026): This project is archived. The core dependency, react-native-callkeep, appears to be unmaintained. Because it enables the key feature of this app, continuing development isn’t feasible unless a new CallKeep-style library is built or the app is rewritten as fully native.
An alternative, react-native-incomingcall, offers similar functionality but currently supports Android only. Since react-native-callkeep is unmaintained, I can’t upgrade to a newer Expo version, so I’m stopping development.
