How it works

Join, pocket, talk.

Joiin is a group voice intercom app for iPhone and Android. Your group shares one live channel. Anyone with a button can hold it to talk.

  1. Get the app and join the group

    The group leader shares a link, a short code or a QR code. Tap, type or scan it and you're in. There's no Wi-Fi to set up and no pairing between phones.

  2. Pair the Flic 2 button

    Flic 2 is a small Bluetooth button. Pair it once in the Joiin app, then clip it to a jacket, strap or handlebar where your thumb can find it.

  3. Lock the phone and put it away

    Joiin keeps working with the screen locked and the phone in a pocket or bag. You hear the group through your usual earphones or headset.

  4. Hold to talk, release to mute

    Hold the button and everyone in the group hears you. Let go and you're muted again, so only deliberate calls go out.

The details

What groups ask us

iPhone and Android together

Mixed groups are normal. Everyone joins the same group whatever phone they use.

What connection does it need?

Joiin carries voice over the internet, using mobile data or Wi-Fi. If a phone briefly loses signal, it rejoins when signal returns.

Does everyone need a button?

No. Leaders usually have a Flic 2 button. Listeners just need the app on their phone. Club Kits include buttons for your leaders.

No mobile signal? Coming soon

An off-grid mode that works without mobile signal is in development. It isn't available yet. Tell us if you need it.
