Square APK

Square is an unofficial Android music client that plays either Spotify Premium or YouTube Music through the same Liquid Glass interface, with a choice made at first launch. People use it for things neither official app offers together, like audio effects, Spotify Connect control, and synced lyrics with translation, all in one player.

Developer: Lelonio · License: GPL-3.0 (open source) · Price: Free

Before you start: Square needs Android 8.0 or later. If you plan to use it with Spotify, you need a Premium account; the app walks you through signing in and registering a free developer app of your own with Spotify to get a client ID, which is needed for search and other features. YouTube Music works immediately with no account, and signing in with Google to bring in your playlists is optional.

Why isn’t Square on Google Play?

Square re-implements Spotify's protocol and reads YouTube Music through its private web endpoints, both outside what Spotify's and Google's terms allow, so it cannot be published on the Play Store. It is published by its developer on GitHub instead.

Is Square safe?

Square is open source under GPL-3.0, and the APK on this page comes from the developer's GitHub releases. It is not on F-Droid, it has no ads, and the app updates itself by checking GitHub for new releases, but using it with Spotify or YouTube Music is against those services' terms, so use it at your own risk. Square comes straight from its developer rather than through Google Play, so it hasn’t gone through Google’s app review. As with any app, check the permissions it asks for and install it if you’re comfortable with them.

How to install

FAQ

Is Square free?

Yes, Square is free and has no ads. The developer accepts optional support through Ko-fi.

Can I use Square with a free Spotify account?

No. A free account can sign in but Spotify only streams audio to third-party clients like Square with a Premium subscription. YouTube Music works with no account at all.

Why doesn't Square show up in Android Auto?

Android Auto only lists Play Store apps by default. Turn on "Unknown sources" in Android Auto's developer settings and Square will appear.
