Why Luup Link

In the audio path.

Does it record WhatsApp, Zoom or Teams calls?

Yes. Luup Link records the audio going to your headphones and coming from your mic, so it works with regular phone calls and with call apps like WhatsApp, Zoom, Teams and FaceTime. Some apps may need Luup Link selected as the audio device.

Will it drain my phone's battery?

Luup Link has no battery of its own. It draws a small amount of power from your phone, similar to a USB-C headphone adapter.

Do I need an app, account or subscription to record calls?

Recording and direct file access need no app, account or subscription. The Luup Link Companion App is optional and in development. Software availability and any pricing will be shared separately.

My wired headphones have no mic. Will that work?
