The app is easy to navigate and simple

The fact that there is an APP available for it by which the speaker's EQ settings can be adjusted as it streams and can control whatever you are streaming from your device (I am using an iPhone6s with wonderfully user-friendly and effective results.

The app has lots of technical for the control freak in your family like my husband is when it comes to electronics

APPThe app is easy to use, it has a little EQ and the utility to connect (Party Up) the speaker to other speakers

The UE Boom App also is an extra bonus, because you can use it to monitor the battery life of the speaker, and from what I am reading you can use the App to facilitate connection to more than one speaker at the same time, which is something you cannot do with a basic one-to-one Bluetooth smart phone to speaker connection.

The app works like it should and is intuitive

It pairs easily and has a useful app for tuning the sound and combining multiple UE Booms into one set
