The Just Dance 2016-22 Controller app serves as Ubisoft's mobile solution for motion tracking across multiple Just Dance game editions. This iOS application transforms smartphones into motion controllers, eliminating the need for dedicated gaming peripherals while maintaining core dance tracking functionality. The app represents Ubisoft's attempt to leverage mobile device ubiquity for broader game accessibility. The app's core functionality relies on smartphone accelerometer and gyroscope data to track dance movements when held in the user's right hand. It supports simultaneous multiplayer sessions for up to six participants, creating a party-friendly environment without additional hardware investments. Navigation through game menus is handled directly through the smartphone interface, though this requires switching between dancing and menu interaction. Compatibility is specifically limited to Just Dance titles from 2016 through 2022, excluding earlier editions that require proprietary controllers. User experience varies significantly based on connection stability and device compatibility. The interface maintains the vibrant Just Dance aesthetic with large, clearly labeled buttons designed for quick navigation during active gameplay. Real-world usage typically involves establishing connection to the console game before dancing sessions, though many users report this initial pairing process as the primary pain point. During actual gameplay, motion tracking generally performs adequately when connections remain stable. User feedback consistently highlights connectivity issues as the dominant concern. Multiple reviews from Ariri6482 (March 16, 2025) repeatedly state 'I have some problems connecting my phone to the game' despite otherwise positive impressions. Monkeyman956 (February 10, 2025) notes the app 'works fine' for supported 2016-2022 titles but confirms persistent bugs and compatibility limitations with earlier game versions. These connectivity problems appear widespread despite the generally positive tone of individual reviews. The app delivers genuine value through hardware cost reduction and multiplayer accessibility, but technical reliability remains questionable. Strengths include eliminating peripheral costs and supporting group play scenarios, while limitations center on inconsistent connectivity and restricted game version compatibility. Ideal use cases involve casual dance parties with supported game editions where users are willing to troubleshoot initial connection setup for subsequent gameplay sessions.
