NOTE: Backbone+ Membership is not available on Android at this time, but will be available soon! You can still download the Backbone App.
Not at all! The Backbone App is a free app with features like controller firmware updates, joystick calibration, and button remapping. We recommend you download this free app in order to keep your Backbone One controller firmware updated.
To use your Backbone One without using the Backbone App, just attach the Backbone One to your device and open any controller-compatible games you have downloaded to your device.
