Universal Music Link Sharing
Official Website • Features • Screenshots • Download
Share your favorite music across all streaming platforms with a single tap
UniTune eliminates the frustration of incompatible music links. When a friend shares a Spotify link but you use Apple Music, UniTune instantly converts it to your preferred platform. Built with Flutter and featuring a glass design, UniTune makes cross-platform music sharing effortless while keeping your data completely private.

Paste any music link and UniTune converts it to all supported platforms in one request. Supports tracks, albums, artists, and playlists across Spotify, Apple Music, YouTube Music, Deezer, TIDAL, and Amazon Music.
Hit share inside Spotify, Tidal, or any other streaming app, pick UniTune from the share sheet, and it converts the link and forwards it to your contact in a single flow. No copy-pasting, no app switching.
Set UniTune as the default handler for music links on Android. When someone sends you a Spotify link in WhatsApp or anywhere else, tapping it opens the song directly in your preferred music app automatically.
Build cross-platform playlists of 3 to 10 tracks from any streaming service. Share them as a single UniTune link or as a QR code with a visual share card. Anyone who opens the link can play each track on whichever service they use.
No accounts, no login, no analytics. All data stays on your device. The only outbound request is to the conversion API.
UniTune shows ads via Google AdMob. The app relies on a self-hosted backend that performs all music link conversions. Running that backend has real infrastructure costs. Ads are the way to cover those costs and keep the app free. No ad data is linked to your identity, and no personal information leaves your device.
Album artwork automatically influences the entire app color scheme for every song you open. Every conversion looks different.
Full history of converted links with statistics on platform usage, sharing frequency, and trends over adjustable time periods.
Glassmorphism UI with smooth animations throughout every screen, consistent with modern Android and iOS design language.
