Just Dance Controller (formerly known as Just Dance 2015 Controller) is a free app by Ubisoft where players can use a smart phone and play Just Dance 2015 (only on the Xbox One and PlayStation 4), Just Dance 2016, Just Dance 2017, Just Dance 2018, and Just Dance 2019 (only on the Xbox One and PlayStation 4) for the Wii U, Xbox One, PlayStation 4, PC, and the Nintendo Switch. The app was an update to the Just Dance 2015 Motion Controller.
This app is only compatible with the Xbox One, PlayStation 4, PC, Wii U, and Nintendo Switch versions of Just Dance 2016, Just Dance 2017, Just Dance 2018, and Just Dance 2019 (the PC and Nintendo Switch versions of the game are compatible with the app for 2017 and onward). However, on Just Dance 2015 and Just Dance 2019, the app is only usable with the Xbox One and PlayStation 4 versions of the game.
With the use of the app, the phone can be used as a controller to count the player’s moves. The phone will work similar to that of a Wii/PlayStation Move/Joy-Con remote. The app also allows you to select the songs through the phone. It also makes a sound when the player achieve a star or perform a Gold Move correctly.
As mentioned before, this app was an update for the Just Dance 2015 Motion Controller app, as it works with Just Dance 2015 as well, but only on PlayStation 4 and Xbox One, just like the Just Dance 2015 Motion Controller app. The update just adds support for the Wii U, PC, and Nintendo Switch consoles for later Just Dance games.
In Just Dance 2016, if the game fails to register moves correctly and counts them as multiple Xs, the game will disconnect the phone in order to refresh it and calibrate the phone for more accurate tracking.
On Just Dance 2015, an update for the game is required in order for the app to work for the game.
The app mainly is used by Xbox One players without a Kinect, PlayStation 4 players without a Move or Camera, and Wii U players without a WiiMote.
In an update on the Just Dance 2016 version (Version 2.2.0) of the app, the Ubisoft logo animation movie was added but it mistakenly have the logo music from Just Dance 2015. This was later fixed in a later update (Version 2.3.2). It was later being removed in the 2018 version (Version 4.0.1) due to the new Ubisoft logo revealed in the UbiBlog on May 31st, 2017.
