Smule, StarMaker and Musixmatch compared for social duets, pitch correction and line-synced lyrics over Spotify, with WeSing covered in the FAQs.
The party used to require a venue, a machine and a printed songbook; now the phone supplies scrolling lyrics, the backing track, studio voice effects and even a duet partner on another continent. The 3 apps in this guide cover the three things people actually want from karaoke at home. Smule is the giant social community with artist duets; StarMaker turns weak pitching into a performance with real-time correction and group rooms; Musixmatch does something different again, turning the songs already in your Spotify library into instant karaoke. They were chosen because the three answers rarely come from the same app.
Smule is the leading social karaoke app: millions of songs, studio-style effects and duets with users worldwide or with well-known artists.
Smule is social karaoke in its purest form. The catalogue runs into millions of songs with on-screen lyrics and studio-grade vocal effects, and the headline feature is collaboration — sing duets and group pieces with users anywhere in the world or, in some cases, with the original artists, then record and share performances inside the largest karaoke community of its kind. The full catalogue requires a VIP subscription, the app is pushy about upgrading, reflected in a 3.8-star rating, and Spanish-language songs are limited on the free plan.
StarMaker is Smule's big rival — real-time pitch correction, group singing rooms and live battles, a broad Spanish catalogue and 500 million downloads.
StarMaker sits at the centre of the gamified karaoke scene with around 500 million downloads. Real-time pitch correction smooths out-of-tune singing as it happens, voice effects add studio sheen, and group singing rooms and live battles turn a solo activity into a social event; its Spanish-language catalogue is broad, and the forgiving correction suits casual singers more interested in fun than precision. The commercial layer is dense: coins and VIP tiers appear throughout, the interface is crowded with gamification, and the free plan serves frequent ads.
Musixmatch turns any Spotify track into karaoke with line-by-line synced lyrics floating over the music app, plus instant translation — the largest lyrics database there is.
Musixmatch is not a backing-track app but a lyrics layer over the ones already installed: it identifies whatever is playing and displays the words synced line by line as a floating window over Spotify, YouTube Music and similar players, drawing on the largest lyrics database in the world and offering instant translation, which finally solves the mystery of what a favourite song actually says. Premium floating lyrics require payment, the free version carries advertising, and the floating window needs overlay permission granted in system settings.

Questions & answers
What is the best free karaoke app?
All three work free within limits: Smule and StarMaker open part of their catalogues at no cost with ads and waiting times, reserving the bulk for VIP. For a one-off party without spending anything, the practical trick is Musixmatch plus Spotify — play the original and large, synced lyrics appear, giving instant karaoke for essentially any song in existence.
Can I put karaoke on the TV for a party?
Yes. Cast the phone to the television through Chromecast or an HDMI cable with any of these apps, or open YouTube directly on the TV, where channels provide backing tracks and synced lyrics by searching for the song plus 'karaoke'. For a classic house party, YouTube on the TV with a decent speaker remains hard to beat; the phone apps add effects and recording.
Can karaoke apps actually help me sing better?
More than expected. StarMaker and WeSing score pitch note by note, which pinpoints exactly where you drift off key, and listening back to your Smule recordings — uncomfortable as it is — is the first exercise every singing teacher assigns. They do not replace real vocal technique, but as playful ear and pitch training they work, and frequent singing improves results through practice alone.
