Mobile drum machine and looper apps are pretty common, but Kovaluu’s Beats and Loops has a potential ace up its sleeve - or in the sole of its shoe - thanks to the option to control it with your foot, as you would a traditional looper pedal.
Obviously, there are risks to doing this - the most obvious being that you’ll end up stomping on your phone and causing it serious damage - but thanks to your device’s proximity sensor, you can use your foot to trigger drum fills, switch song parts, record loops and more. You get a variety of drumming styles, and the parts were recorded on a vintage Ludwig kit.
Loops can be recorded through your device’s internal mic or via an audio interface, and all recordings automatically sync to the current tempo. A tuner and a metronome are included, too.
