Mancing Dolecules has introduced Everyday Looper - a 4 track looper for the iPhone, with strong emphasis on waveform visualization, direct track interaction and simplified volume management.
According to the developers, Everyday Looper is intended for guitarists, singers, beatboxers and "sound torturers." (Glad they include me in there.)
Note: This app focuses on recording. No pre-recorded samples are included and iPod Touch users will need on external microphone.
Pricing and Availability
Everyday Looper is available now and retails for $3.99.
