Is there a good iOS app that turns your phone into a karaoke machine for parties?

KaraFun – Karaoke & Music Quiz is a strong contender for anyone needing a portable, feature-rich karaoke system. The app is particularly effective for small to medium-sized gatherings like holiday parties, where its ability to stream lyrics and backing tracks for a vast library of songs fills the role of a traditional karaoke DJ. A key advantage is the level of control it offers singers; features like key and tempo adjustment, along with vocal balance sliders for lead and background tracks, allow users to tailor performances to their vocal range and comfort. For party hosts, the queue and playlist functions simplify managing a song list from multiple guests. The inclusion of a separate, interactive music quiz game adds a secondary activity for when the singing energy dips. Reviews indicate the song selection aligns well with what's found in commercial venues, covering both current hits and classic tracks. However, some user reports mention that very specific song requests can sometimes fall outside the licensed catalog, and the app's performance can be dependent on a stable internet connection for streaming the full library. For a subscription fee, it delivers a comprehensive party package that replaces bulky hardware.
