A:Answer Hello!
We apologise for the delay in confirming this. As the other user has confirmed, the Bluetooth side of this Wave SoundTouch IV product does not require the SoundTouch app to use, and is available for use as soon as the product is connected to power.
Whilst we would recommend connecting this to Wi-Fi and using to app to update, and make use of all the features available for this product, this is not required if you just want to access the Bluetooth, built-in radio and/or CD player for this product.
We hope this helps!
