Comments on Castafiore - Subsonic client for Android

★★★★★ Clara Bruch · Jun 30, 2025

The rare subsonic client with a good interface and native palindrome support. Great work, please keep it up!

★★★★★ Daniel Dutra · Sep 7, 2025

Just found Astaire. It's all I wanted, it could become the de facto music player for subsonic servers. Beautiful interface, great usability, user UX customization was a great addition since last update. I'm using ultrasonic because, right now, it is the only app that's free and works well. I only miss the ability to set the number of cached songs and real time cached song icon update

★★★★☆ Sergey Lapitsky · Feb 27, 2026

Good app, but would be great if offline songs/albums could be seen in a separate menu or something like that. I mean, without this simple option interaction with offline albums, without connection to a server, becomes very complicated.

★☆☆☆☆ Luke Etyrnal · Apr 30, 2026

Astaire complains of "incompatible air sonic rest protocol version. Server must upgrade". Yet allows a 'legacy mode'. Even tho air sonic server is recent. Running on an android watch. All my other subsonic clients connect to my air sonic server -- ONLY Astaire refuses to. Way to BREAK things.

★☆☆☆☆ Róbert · Sep 22, 2026

Unfortunately not works. I can not connect to server. No automatic server search. no, any help how we fill the input fields.
