I’m just using it simply to stream from my phone. Functions are basic but no problems at all. A happy camper. ### 2/5 — No response to multiple requests for support *2026-01-18, version 2.8.13304* Do not answer requests for support. ### 2/5 — Missing major stream *2025-12-21, version 2.8.13304* Update: unable to sign into deezer account. Verified email and password but 4stream app just fails can you fix deezer login at a minimum? Taking away another star until built in feature actually works. Can you add integration for LiveOne.com ? Formerly slacker radio. One of the original music streams as old as pandora! Thanks in advance. ### 3/5 — Dezzer lädt nicht *2025-11-29, version 2.8.13304* Kann mich mit meinem Deezer Account nicht anmelden. Wenn ich auf die Internetseite von Deezer gehe, ist eine Anmeldung mit den Anmeldedaten problemlos möglich. Auch die beschriebene Anleitung für Spotify funktioniert so nicht. Sonst kann ich zur App noch nicht viel sagen da erst seit einem Tag im Einsatz. ### 4/5 — Nice though needs one improvement *2025-11-05, version 2.8.13304* Really good app that I use to airplay music via Apple Music app to an Arylic S50 pro. The Arylic is connected to an Onkyo TX NR6100 receiver; Zone 2 with wired outdoor speakers. This setup allows me to control music volume & selection directly from my iphone/ipad & app and gives more power to the speakers which greatly enhances sound. The EQ in 4Stream also helps with that as well. Without the Arylic S50 & this app; Onkyo Zone 2 sound is not that great. It would be a valuable improvement if the 4Stream app included a sound balance LR sliding bar instead of the current option of hearing sound either from only the R or L speaker or both R&L speakers. ### 4/5 — Missing major stream *2025-10-13, version 2.8.13304* Can you add integration for LiveOne.com ? Formerly slacker radio. One of the original music streams as old as pandora! Thanks in advance. ### 2/5 — Can‘t use it with Apple Music *2025-10-03, version 2.8.13304* Used to love the App, but switching to Apple Music from Spotify made it more or less useless for me… ### 5/5 — Triangle AIO *2025-08-15, version 2.8.13304* Cette application prend en charge ma triangle AIO 3 et fonctionne bien mieux que l’application délaissée par Triangle ### 5/5 — Super appli *2025-07-22, version 2.8.13304* Très bonne appli qui prend en charge toutes les applications Deezer Spotify et même les e radios en ligne. ### 2/5 — Geht besser *2025-03-29, version 2.8.13304* Ich nutze 4Stream hauptsächlich für einen Keces Ebravo streamer in Verbindung mit qobuz. Gelgentlich stürzt dad System ab, die Bedienoberfläche ist nicht intuitiv, die Menüs u logisch. Leider bietet Keces keine Qobuz Direktverbindung wie bei Tidal.... ## Frequently asked questions about 4STREAM ### What does the 4STREAM app do?
