Is deepcut.fm free to use?

Yes. According to the site's own description, deepcut.fm lets you "play music together for free on the web, iPhone, or Android device." No pricing page, subscription tier, or payment platform is referenced anywhere in the available site information, so there is no indication of a paywall or paid plan.

What the free claim covers

The description ties "free" directly to the core activity — listening to music together in real time — and to all three access points it names:

• Web browser
• iPhone
• Android device

That means the free claim isn't limited to a trial platform or a single device. If you can reach deepcut.fm from any of those, the stated experience is the same one described as free.

What is not stated

A few things are simply absent from the available information, and it's worth being precise about them rather than assuming:

The absence of a paywall in the description is a good sign, but it isn't the same as a guarantee about account requirements or future changes. If you want certainty before inviting friends, the quickest check is to open the site and start a session — the flow itself will show you whether any sign-up or payment step appears.

Why this matters for how you'd use it

Because the free claim is attached to real-time group listening, the practical takeaway is that cost shouldn't be the thing that stops you from trying it with a friend. You can test the whole loop — open it on the web, or install it on iPhone or Android, and start a shared session — without first deciding whether it's worth paying for.

If a paid option does exist somewhere the description doesn't cover, it would most likely be an optional upgrade rather than a gate on the basic "listen together" feature, since that feature is the one explicitly labeled free.
