Quantiloop is a versatile live looping application designed for iPhone that mimics the functionality of a traditional hardware loop pedal. It supports hands-free operation, allowing users to connect a MIDI foot controller or utilize preset loop lengths for automatic recording. The app features large on-screen controls, making it easy for vocalists and beatboxers to manage their performances without complicated setups.

The application allows for the creation of four tracks with unlimited overdubs, enabling users to layer sounds and create complex compositions. It includes a built-in rhythm guide, MIDI control options, and various effects that can be applied to both input and output. With features such as quantization, real-time tempo control, and extensive MIDI support, Quantiloop enhances live performances and offers a professional sound experience, while some advanced functionalities are accessible via a Pro upgrade.
