Christmas Budget & Receipt Tracker App

I’m planning a cross-platform mobile app that helps users stay on top of Christmas spending from start to finish. The same build should run smoothly on both iOS and Android, with a simple email-and-password sign-up so people can keep their data secure and sync across devices...
