icon Subster is a pass-and-play music party game for your own music collection. A mystery song plays blind — no title, no artist, no year. Your job: place it on your timeline by guessing whether it came out before or after the songs you already hold. Guess right and you keep the card. First to 10 cards wins.

It works like the card game Hitster, but with no physical cards, no accounts, and no backend: the app talks directly to your Subsonic-compatible music server (Navidrome, Airsonic, Gonic, …).

Features



Privacy

No accounts, no ads, no analytics. To rank songs and resolve years, only artist/title of library songs are sent to the public Deezer, MusicBrainz and Wikidata APIs — nothing about you or your server. The "Online metadata" setting has three levels: full, "No Deezer" (drops the only proprietary service but keeps MusicBrainz/Wikidata years), and offline, where only your own server is contacted.

You need a Subsonic-compatible music server to play. Your server credentials never leave the device, and are stored as a salted token rather than the password itself — except for servers that only accept legacy authentication, where the app tells you that the password has to be kept.

WhatsNew:

• Much more accurate release years: a song is dated by its first official release, so a bootleg or promo pressing no longer makes a card years too old
• Servers that never expose MusicBrainz IDs — Nextcloud Music always — now use the album to identify the recording, fixing wrong years and missing songs
• A song whose year can't be established is left out rather than dealt with a wrong one
• Failed MusicBrainz requests are retried; a slow Wikidata lookup no longer holds up the deck

anti Anti-Features:
  • NonFreeNet (this application promotes/depends a non-Free network service):
    ⇒ Ranks song popularity via the proprietary Deezer API, on by default
  • TetheredNet (This app is bound to a certain network service):
    ⇒ deezer.com, musicbrainz.org and wikidata.org are not configurable

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device.
