Is there a good iOS app for singing karaoke duets with a friend who lives far away?

StarMaker is a strong contender for users seeking a social karaoke experience with remote collaboration at its core. The app excels by providing a feature specifically designed for duets, where one user can start a song and invite another to join, regardless of their physical location. Each participant records their vocal track separately, often with guidance from on-screen lyrics and a pitch evaluator, and the app seamlessly merges them. This setup is ideal for friends, family members, or even casual singers looking to connect over music without needing to be in the same room. Beyond duets, the app fosters a community through features like in-app messaging, public performance feeds, and virtual gifting, turning a solo activity into a shared social event. However, reviews indicate occasional account verification issues, with some users reporting unexpected blocks despite entering correct age information, which can disrupt the social connections the app aims to build. The free version includes ads and may limit access to the full song catalog, requiring a subscription for unlimited singing. For its primary purpose of remote musical collaboration, StarMaker delivers a functional and engaging platform, albeit with some administrative quirks that prospective users should note.
